Since the tiny house interest has been steadily increasing, people often wonder what it’s like to live in a tiny house. How do they feel? How big are they? What is the average size of a tiny house? Let’s look into these questions.

So, what is the average size of a tiny house? The average size of a tiny house is 8′ 6″ (2.6 m) by 28′ (8.5 m), leaving the square footage at 238 (72.5 m). But a tiny house can be anything under 500 sq ft (152.4 sq m) (or sometimes 600 sq ft (183 sq m)). Tiny houses come in lots of different sizes and are customizable.

My husband and I have been living tiny and working for tiny house companies for almost four years now. We have lived the life and watched hundreds and hundreds of other houses being built. Let’s look more into the sizes of tiny houses.

What is the Average Size of a Tiny House?

The average size of tiny houses on wheels (THOWs) now is 8′ 6″ (2.6 m) by 28′ (8.5 m), leaving the house at 238 sq ft (72.5 sq m). The average size used to be smaller, around 8′ (2.4 m) by 20′ (6 m) leaving you with 160 square feet (48.8 sq m) of space inside. This was about 8 years ago, closer to when the tiny house trend first hit.

Since interest in tiny houses has skyrocketed a lot more people are going tiny. Many people who buy THOWs now do not move them around at all, these homes are stationary.

People are starting to realize that you cannot fit much in an 8′ (2.4 m) x 20′ (6 m) and so they have been opting for bigger homes. Bigger homes are harder to tow, but you have more space in them.

Since many people are no longer towing their houses much at all anymore, it makes sense to live in something a little larger. Thus the average size of tiny houses has increased over the years.

*This information comes from iPropertyManagment.com, tiny house companies, people who live in tiny houses, and research about other tiny housers.

How Big are Tiny Houses?

Tiny houses can be anywhere from 90 (27 sq m) to 500 square feet (152 sq m). Most definitions of tiny houses say under 500 square feet (152 sq m), however, some say 600 (183 sq m). For example in Canada, it is considered a tiny house if it is under 600 square feet (183 sq m).

Tiny houses can be very small. About the smallest, you will see is an 8 (2.4 m) foot by 12 (3.7 m) foot. These houses are 96 square feet (29 sq m). Anything smaller than this is technically a tiny house, but it is now called a micro house.

You can buy a micro home, which is 8 foot (2.4 m) by 10 foot (3 m), giving you 80 square feet (24 sq m) of space inside. However, these are not usually considered tiny houses, they are micro homes

Tiny houses have grown over the years. In 1998, the average tiny house was 9′ (2.7 m) by 10′ (3 m), equaling 90 square feet (27 sq m). (source). This is about the smallest tiny house you can get now.

As they grew in popularity, people started to want tiny houses but also some more space. In 2010, the average tiny house was 8′ (2.4 m) by 20′ (6 m), which is 160 sq ft (49 sq m). (source)

And now, as reported in 2018, the average tiny house is 8′ 6″ (2.6 m) by 28′ (8.5 m), which gives you 238 sq ft (72.5 sq m). We can see that tiny houses are trending upward in size.

How Much do Tiny Houses Weigh?

Knowing the weight of your tiny house is very important if you are going to be towing it. You will need to know how heavy duty of a truck you need or who to hire.

So, how much does a tiny house weigh? The weight of a tiny house is based on size. The average tiny house is 8.6′ (2.6 m) by 28′ (8.5 m), which usually weighs around 15,000 lbs (6804 kg), fully loaded, or often estimated at 10,000 lbs (4535 kg) in dry weight. Of course, it depends on the materials and what you have inside. Let’s look at the average weights for other sizes of tiny houses.

Tiny houses are usually much heavier than people think. You have to keep in mind that this is nothing like an RV. Tiny houses are usually built with a wood frame and real building materials.

Even just a 24-foot (7.3 m) trailer is around 2,000 lbs (907 kg). And if you are building a bigger house then your trailer will weigh even more. Our first home was 35 feet (10.7 m) long and the trailer weighed 3,600 lbs (1633 kg).

About the smallest tiny house, you get can is an 8′ (2.4 m) by 12′ (3.7 m). You can get a smaller house, that could be around 8′ (2.4 m) by 10′ (3 m), but these are not really tiny houses anymore. It will be too small to have normal tiny house aspects, like a kitchen, bedroom, and bathroom. These are often called micro homes.

An 8-foot (2.4 m) by 12-foot (3.7 m) tiny house will weigh, on average, between 5,000 lbs (2268 kg) to 7,500 lbs (3402 kg). It is a smaller house, so less weight in materials but it also varies dramatically based on what you have in it. If you want this to mostly just be a bedroom and a bathroom, then it will weigh much less.

The next size up is usually an 8′ (2.4 m) by 20′ (6 m). These used to be the most common size tiny house, but now it is a 28-foot (8.5 m) long house. An 8-foot (2.4 m) by 20-foot (8.5 m) tiny house weighs around 12,500 lbs (5670 kg).

This is MUCH heavier than the average camper, which is 6,700 pounds (3040 kg) (source). And this is still considered a small tiny house!

The average weight of an 8′ 6″ (2.6 m) by 28 (8.5) foot tiny house is about 15,000 pounds (6804 kg) fully filled. This is more than a typical F150 can tow. With this house you will need a heavier-duty truck, maybe even a diesel, to pull it.

If you are going even larger then it will be even heavier. Our house was 8′ 6″ (2.6 m) by 35 feet (10.7 m) long and it weighed 21,700 pounds (9843 kg)! This was also without some normal appliances most tiny homes have in them.

Now you can drastically reduce the weight of your house by the materials you use. Some siding can be heavier than others, some countertops are heavier than others.

But if you really want to reduce the weight of your tiny house, use metal studs. A metal frame will reduce the weight by 35%! This is huge if you plan on traveling in your home.

However, the reason people don’t usually use metal is that it is a lot more expensive. A metal frame will essentially cost double what a wood frame would have cost.

Also, you will need to pay more for insulation. You will have to use spray foam insulation in a metal frame house due to condensation and the thermal bridge.

Metal needs a vapor barrier to keep condensation out when the temperatures are changing. Similarly, you will need spray foam to better insulate against the thermal bridge. Metal gets very cold and transfers that temperature to all other materials it touches, so you need to protect against that.

Spray foam insulation is definitely more expensive than normal batten, but it is also better. It has a much higher insulation quality. So your home will be more expensive, but it will also be lighter and better insulated.

How Many Tiny Houses are There?

It is very hard to determine how many tiny houses there are out there. There is no database collecting data on how many people buy tiny houses. They are not like regular homes.

Dan George Dobrowolski, the owner of Escape Tiny Homes, has been building small houses for over 25 years now. He estimated that around 2,000 tiny houses were sold in 2016.

However, in an interview in 2017, Dobrowolski stated, “Nobody has a fix on this. Whatever measuring stick people are trying to use, they don’t get it.” We do not know how many tiny houses have been built.

If you want to see how many people have listed themselves as owning a tiny house then check out the map they have created.

How Long Have Tiny Houses Existed?

People have been building small homes for thousands of years, however, what we consider the tiny house movement started in the 90s. Jay Shafer built the first tiny house on wheels in 1997 and started a tiny house building company from there.

This was when tiny houses on wheels (THOWs) are thought to have started. Although, people have technically been building tiny houses for a long time. Considering many cultures started by having very small homes.

Tiny houses have been growing in popularity since the early 2000s. Interest in tiny houses skyrocketed when HGTV came out with its show on tiny houses in 2014.

Tiny houses are definitely not a fad, they have been around for a very long time now. More and more people are starting to see the benefits of having a tiny house, and cities are starting to change zoning laws to allow them as well.

63% of Millennials say they would live in a tiny house now. Over half of our future generations not only want to keep tiny houses around but they would also live in one.

The Future of Tiny Homes

Tiny homes have been growing in popularity and they will only continue to do so. As we can see the younger generations are more excited about tiny houses, so they will perpetuate their popularity.

One change we can see is the size. As tiny homes spread across the nation they will continue to get slightly larger. We have been seeing this trend now:

• In 1998, the average tiny house was 9′ (2.7 m) by 10′ (3 m), equaling 90 square feet (27 sq m).
• In 2010, the average tiny house was 8′ (2.4 m) by 20′ (6 m), which is 160 sq ft (49 sq m).
• And now, as reported in 2018, the average tiny house is 8′ 6″ (2.6 m) by 28′ (8.5 m), which gives you 238 sq ft (72.5 sq m).

Another trend we are likely to see with tiny houses is their luxury. According to iProperty Management, tiny homes have been steadily increasing in luxurious touches.

A common idea now is to “downsize and upgrade”. It is true when you have such a small home and you are already saving lots of money, why not splurge on the finishing touches.

If you have a tiny house then it is not as expensive to buy expensive items. In our first house, we bought the most beautiful real hardwood floors that were $5 a square foot. But it was still way cheaper to buy our floors than to buy cheap floors for a normal size home.

An additional trend we are seeing is that tiny houses are not just being used as homes anymore. Lots of people are buying tiny houses for Grandparents’ quarters, offices, party pods, vacation homes, hunting cabins, and more. There are so many uses for tiny houses, people are starting to see the benefit of having a mobile, livable home.

We have seen companies buy tiny houses built as a party area with just seats and a bar or buy a tiny house that is just several bathrooms. The mobility, customization, and stability of tiny houses are making them soar in popularity.

As tiny homes grow in popularity we will see cities and counties become more accepting of them. This is the trend that excites me the most.

You can already see lots of cities have made an effort to make tiny houses legal. As more and more people start to see the benefits of living tiny we can only hope that they will become more accepting.

There are so many benefits that come from tiny homes. One major benefit is the carbon footprint, tiny homes are a lot better for the environment than full-sized homes.

Tiny houses use fewer materials, less lumber, insulation, and everything else. They also typically have smaller or fewer appliances, which then use less electricity.

There is less space to heat and cool, which drastically saves on electricity as well. And many tiny houses even run on solar. It is said that cutting a house in half will then reduce its emissions by 36%. Imagine how much it is reduced by a tiny house!

On top of that, over a period of 70 years, more than 80% of a home’s greenhouse gas emissions are from electricity and fuel consumption. Emissions would be cut down dramatically by having less space to heat and cool, and by using less fuel.

All around tiny homes are great options for a better environment and the cost benefits. There are a couple of reasons that they will continue to rise in popularity.

The Sizes of Our Tiny Homes

We have been living tiny for almost 4 years now and we have built three different homes in that time. My husband has built all of them and they have all been different styles.

Our first house was a typical THOW, with cedar siding. It was 35 feet (10.7 m) long by 8 foot and 6 inches (2.6 m) wide, with two loft bedrooms that could fit king-size beds. It was beautiful but also very heavy and not as mobile as we would have preferred.

Our next house was built out of a container. It was a 40 foot (12.2 m) container with a 5 foot (1.5 m) porch, so it was 35 feet (10.7 m) long by 8 foot (2.4 m) wide, with no lofts. This is not a mobile home.

The next house we built was out of a cargo trailer. This house is 14 feet (4.3 m) long and 7 (2.1 m) feet wide, with a 3 foot (0.9 m) V nose over the hitch. We have taken this house all over the country and it has been great!

Heating a tiny house may prove to be more involved than it sounds. With so many options it can be difficult to determine which option is best for you.

So, how do you heat a tiny house? There are several options for heating a tiny house. One of the most common is a mini split, this is similar to central air and heat, but it is a single unit built for a large room. Many tiny houses also have a wood stove as a primary source of heat, especially for those that are off-grid. There are several other options as well.

My husband and I have been living tiny for almost 4 years now and we want to share our knowledge with others. We have used a few different options for our heat sources, so let’s look at the pros and cons.

Mini Splits for a Tiny House

On-Grid Systems for Primary Heat

Mini splits are one of the most common heating method for tiny houses due to their convenience and simplicity, especially for those on the grid.

Pros

• Convenience: You can set a temperature, you can set a timer, you don’t need to mess with it at all if you don’t want it.
• Features: They also have air conditioning, a fan, and other options.
• Visually Appealing: They are typically a white rectangular box that looks very modern.
• Size and Space: It is small enough it can fit in most tiny houses and is mounted high up on the wall, so it does not interfere with your space.

Cons

• Price: The good ones are pricey, all of them are around $500-$2,000.
• Power Usage: The more expensive units are better on power, however compared to other types of heat, they use a lot of power.

When getting a mini split for a tiny house you should get SEER rating of 20 and above. This is the efficiency rating for the unit and anything less than that is not recommended.

Important Note: If you are using your mini split for heat in the winter you will need to select the “follow me” mode on the remote and leave it at counter top height. The mini split will automatically turn off when the air around it reaches the temperature you set. Since these units are installed near the ceiling and heat rises, they will cut off when your house is still very cold. Selecting the “follow me” mode means that the mini split will turn off when it reaches the correct temperature around the remote.

Mini splits are most commonly known for their convenient air conditioning in tiny houses. However, most mini splits also offer heat as well. These are simple, sleek, convenient and easy to use.

You can set a temperature or a time to turn on and leave it alone. It is the most similar to central heat and air that a tiny house can get, since the house would be too small to actually install the central heat and air ducts.

They are very attractive and modern looking as well. They look like a white box placed up higher in the room. These are in most tiny houses on wheels, but other tiny houses use them too.

The cost ranges on mini splits, it is better to spend a little more on a nicer one rather than trying to cut costs here. The cheaper ones may look similar to the costly ones, however they will use more power.

The downfall of mini splits is their power usage. Whether you are concerned about your environmental footprint or your solar power, a mini split will use a lot of power.

Wood Stoves for a Tiny House

Off -Grid Systems

Pros

• Power Usage: Can use a little power if you plug in a blower, otherwise most do not use any power.
• Abundant Fuel Source: Even if your power goes out you can still have heat and you can burn any extra wood you have.
• Heat: You get very hot heat!

Cons

• Price: Wood stoves are expensive, especially if you are buying a small one!
• Getting Wood: You will either have to cut or buy wood. The cost of buying wood is usually a lot cheaper than your electricity bill if you have electric heat.
• Maintaining a Fire: Especially with the small stoves.

Recently, a few companies have been making tiny wood stoves perfect for tiny houses. They are small and simple and people love them. But they are not perfect. Thy are pricey (around $1,000) and you have to be sure to maintain your fire constantly.

Also these stoves have very small stove pipe, which is extremely hard to get, you will likely have to order it form those companies. Moreover, you will have to clean your pipes a lot more often due to how small the stove pipe actually is and the build up that accrues.

But wood stoves are still one of the best options. One of the best features is that they will still heat without power! If anything happens and you lose power you can still have heat.

Lots of people use wood stoves as their main source of heat throughout the winter and they are probably just as popular as mini splits. We have used a wood stove in two of our houses in very cold climates and they worked great.

Wood stoves are so common in tiny houses for multiple reasons. Who wouldn’t want to curl up by a warm beautiful fire glow and a chestnut smoke smell in your cozy tiny house?

They are beautiful, classic, and great at heating! We have often had to open our windows because the fire was so hot. This is one of the hottest sources of heat you can get!

And it can be very cost effective in your daily life. After the initial cost of the stove all you need it wood. If you live somewhere you can cut your own than you wouldn’t have a heating bill at all.

If you need to buy wood and live in a wooded area than it can be relatively cheap to buy the wood you will need to for the winter. The year we spent in Utah, we paid $300 for wood for that winter.

Air Heaters (Diesel or Propane)

On- or Off-Grid Systems

Pros

• Price: You can find some cheap options that work relatively well. They are also relatively cheap to run throughout the year, you buy a couple gallons of diesel once or twice a week.
• Convenient: You can set a temperate and a turn on time. However, it will not turn itself on and off, unless you buy the name brand models. It will only get higher and lower in temperature.
• Size: They will fit in any tiny house.
• Power Efficient: They use very little power.

Cons

• Difficult to Fix: The cheap models are manufactured in China, so if you live in America or most other countries you will have a hard time finding parts, or someone who can work on them. (Unless it is a true Espar or Webasto heater, then you can take them into a Semi truck shop and they will fix it or put you in contact with someone who can.)
• Maintenance: Every year you need to clean out the fuel tank and before the winter you need to clean out the actual unit.

Air heaters use an air exchanger which draws fresh air from outside or air from inside, and then passes it over an aluminum block with fins, which heats the air. The exhaust and intake of the combustion unit are located outside, thus no concern for carbon monoxide.

These come in two different options: diesel or propane. You can buy them off of Amazon for relatively cheap. Unless you want to buy one of the original name brand units.

The original brands that you see in Semi Trucks are either an Espar or Webasto diesel heater. These heaters are definitely more expensive but last much longer, are almost half the size, and are more efficient.

I love our diesel heater!

I love our diesel heater! This is something not many people have heard about, but they are a great option. Diesel heaters are commonly used in semi trucks for heat overnight, when their truck is off.

I have not heard of many tiny houses that use this as their heat source, but they should start! My husband’s dad has been a truck driver for years and so my husband thought this would be a good option in our newest house, a 14 foot cargo trailer.

We couldn’t fit anything large in this small of a trailer and we were about to live in it during the winter months in Washington state. So we needed something reliable and cost efficient.

Most truck drivers go with a good name brand heater, like Espar. However, they are very expensive. We found a few options of similar air diesel heaters on Amazon with good reviews.

We purchased one of those and it worked great at first. And then it didn’t. We had to keep cleaning it out for it to run at all. We contacted the sellers off of Amazon and they were great, but didn’t totally understand.

They kept offering us partial refunds to pay for someone to fix it. But there is no one in America that works on these heaters. Even though they are actually built quite simply.

After enough time looking at it my husband found that part of the fuel pump was broken. After some searching and fixing the heater worked great again.

We bought another heater from them a year later, the company has made some adjustments and they work even better now. Moral of the story is, be sure that everything it set up correctly and nothing is broken.

The company does allow refunds if yours is broken and the sellers that we went through were great. I would definitely recommend tiny housers use this as a heating option. It keeps our house so warm!

Important Note: Clean out your fuel tank as well a possible at the end of winter. If the fuel is left for the whole year it will split and be difficult to clean and will not work with your heater. Use fresh diesel. You will also need to clean out the unit once a year, before you start using it, to ensure it runs smoothly.

Solar Air Heaters

Off -Grid Systems

Pros

• Energy Efficient: You can install these on your walls and it does not use any power.

Cons

• Supplemental Day Heat ONLY: They will not work at night!
• Price: As with anything solar, the initial cost is expensive, but you do not pay anything else for the heat.
• Not Enough Space: They can only heat a small space and you may need a couple, even for a tiny house.

Solar air heaters use a series of aluminum tubes, on the outside of your house, that the air is pulled through and sent into your house. The air traveling through the tubes is heated by the sun.

These are great options for sheds, greenhouses, or any places you will be working in during the day. They will not work at night or on really cloudy days.

Anything solar is a popular option with tiny houses. Buying a solar heater allows you to lessen your environmental footprint by not using wood, fuel, or unclean forms of electricity during the day.

They can be expensive for the initial cost, but you do not have as much of a heating bill afterwards. Buying anything solar is typically an investment, it will cost more up front but saves you money over the years.

Also be sure you will have enough sunlight where you live to keep the heat source going. This is ONLY supplemental heat, you will have to have another heat source as well.

Propane Heaters

On- and Off-Grid Systems

Pros

• Convenient: They easy to get, set up, and use.
• Price: You can find a lot of cheap options.

Cons

• Burn up oxygen: Many of the propane heaters, especially the cheaper ones burn the oxygen in your air.
• Open Flame: Most of these heaters have an open flame, which can be unsafe around children or pets. This can also be a potential fire hazard, especially in such a small space.
• Not Efficient: They do use a lot of propane.

There are a couple of common propane heaters. Portable cabin heater (like a Mr. Heater) or marine grade propane heaters (like the Dickinson heater). The Dickinson heater is very popular with tiny houses and much better than the cheaper options.

The Dickinson is a vented marine grade unit, so you don’t have to worry about burning oxygen or an open flame, it’s enclosed. However, it is not cheap. They are around $1,000.

There are other common propane heaters that are much cheaper, but again they will have more problems. Most propane heaters are not thermostatically controlled, so you cannot control the temperate in your house.

Radiant Floor Heating in Tiny Houses

On- or Off-Grid Systems

Pros

• Space: Obviously this does not take up a lot space in your tiny house, since it runs in the floors. But it does take up 2 cubic feet of space for the system.
• Source: It heats the floors, which are usually the coldest part of the house. Heating the floors also heats the whole structure.

Cons

• Not Sufficient: You will likely need a back up heat source if you live somewhere cold even though you may not use it very often.
• Price: The initial cost can be high and you still have a bill for the electric afterwards, however it is not as expensive as an electric heater.

Radiant floor heating is starting to become a popular option, and not just for tiny houses. Having warm floors definitely has an appeal.

This method runs tubes through your floors flied with water and then heats the water when you turn it on. They use a tanked solar heater as well and may other components.

It would be best to have this installed professionally since having a leak can ruin an entire tiny house. Having one of the pipes burst is a legitimate concern.

However, I have not heard of many people saying they have had a leak. If you do get one you would have to replace all the pipes and likely your whole floor.

Another concern is that since this only heats the floor you will need a back up source of heat. However, living in a tiny house is different than a regular house.

I have heard another lady say that she basically only uses her radiant floor heating in the winter. She spend a -25 degree Fahrenheit winter in Colorado and 95% of the winter she only used her radiant floor heating.

I always recommend having a back up heat source if you live somewhere cold, just in case. But especially for this type of heating, since you are only heating the floors.

Other Electric Heaters

On-Grid Systems

Pros

• Convenient: They are easy to use and can be picked up at a store.
• Price: They are relatively cheap to purchase.

Cons

• Space: They are awkward and take up weird places for space.
• Power: They use a lot of electricity.
• Overload of the System: These heaters usually overload the system and will flip a breaker.

Some tiny housers who are hooked up to a secure source of power just buy an electric heater because they are easy to use and find. They can be simple to use for your primary heat source.

I would not recommend these for a long term source of heat, but if you just moved into a tiny house and need something. Then these can work for a little while.

However, since there can only be so many circuits in a tiny house, these heaters usually overload the system and flip a barker. They just pull too much power for you be running other electronics off of the same circuit.

Definitely invest in another heat source rather than just pure electric heaters. They are simple and easy to buy, but it will benefit you in the long run to invest in something else and will make for a more cozy tiny house.

If you are in need I recommend grabbing a propane heater instead of an electric heater, especially if you run off of solar. Electric heaters use a lot of power and is a very inefficient way to produce heat.

Pellet Stove

On- or Off-Grid

Pros

• Consistent Heat: They will run as long as you keep them filled, no need to restart a fire. All of them are thermostat controlled.

Cons

• Price: They are expensive and still use electricity and pellets to run.
• Space: They are usually large and take up room, accounting for the clearances they require, it will be too big for a lot of tiny houses.
• Power Usage: Consistently pulls power .
• Getting Pellets Constantly: You will always need to get pellets for your stove.

They do have some wall hung pellet stoves, but these are VERY expensive. And you still have to buy pellets and pay for electricity. And most of them will not run without power, unlike a wood stove. So if you lose power, you lose heat.

It is very unlikely that you will see a pellet stove in a tiny house. I bring this one up because I have had many people ask me about these. Pellet stoves are not really tiny house friendly.

Pellets stoves are a great source of heat, you get all the benefits of a wood stove without having to start a fire everyday. As long as you keep the pellets full you do not have to worry about your fire going out.

But these are usually too large for a tiny house. And with the clearances they require it will take up a lot of room.

We looked into getting one of these for our house before. They seem convent and we love the type of heat you get from a wood stove. But pellet stoves do use a lot of power.

They require electricity to keep ruining and monitor temperature. You would be buying pellets and paying for electricity. Given that we live off of solar we are very cautious about our power usage anyway.

Always Have a Back Up Heat Source

I remember living in Utah and waking up to -3 degrees Fahrenheit. We were not completely prepared when we first moved there and did not have enough heat. Always have a back up!

One day I woke up to a broken hot water heater. The pipes froze overnight and cracked. Most people take heating their home for granted. Heat is not something to take lightly.

Related Questions

How do you get A.C. in your tiny house? There are a few ways to cool a tiny house. The most common options is a mini split. A mini split is similar to central air and heat but is used for one room, which is big enough for a tiny house. This is the most convenient and common option. However there are other ways to cool a tiny house.

How do tiny houses get power? Tiny houses typically hook up to a power source through a 30 or 50 amp RV inlet. Lots of tiny houses are off-grid and those ones usually use solar for their power. There are some other options, like a generator. But it is a bad idea to use a generator constantly for a tiny house.
