How Tall Are Houses? (1-,2-, and 3-Story Houses)

When planning the construction of a house, the height of the building is one of the first elements that needs to be considered. In most geographic locations, the general height of homes is similar due to local laws and regulations. However, in general, how tall are houses?

Most houses range from 12 feet tall to 45 feet tall. There is no definitive answer to how tall a house is because the measurement often varies by location and roof height. Homes built in different geographic locations must abide by different regulations.

In this article, I’ll dive into how tall a 1-, 2-, and 3-story house usually is. I’ll also discuss the average height of a home’s roof, why house height varies, the average height of a garage, and the best ceiling height for a house. Let’s get started!

How Tall Is a 1 Story House?

A 1 story house usually is 12-15 feet tall. However, roof height is one of the most significant variables in homes, and the overall height of a 1-story house will largely depend on the roof size. So while one 1-story house might be 12 feet tall, another might be 13.5 feet tall.

If the ceiling of a 1-story house is on the shorter side and the roof is flat, the home might be a little shorter than 12 feet. However, in most cases, 1-story houses are between 12 and 15 feet tall.

How Tall Is a 2 Story House?

A 2-story house usually is 18-25 feet. Like any building, the height of a 2-story place largely depends on the roof and ceiling height on each floor. A 2-story house with low ceilings on each floor can be as short as 18 feet.

The average height of a house story is around 10 feet, but it can always be slightly shorter or taller than this. So if a 2-story house has two 10-feet-tall stories and a flat roof, it will be around 20 feet tall.

However, if it had a higher roof, it could be much taller than 20 feet.

How Tall Is a 3 Story House?

A 3-story house is usually between 30 and 45 feet tall, depending on the roof height and foundations. The exact size will also depend on the height of each floor. The average house floor is around 10 feet tall, so a 3-story house with a flat roof will be 30 feet tall.

However, many 3-story houses don’t have flat roofs, so you need to consider that when determining how tall a home is.

Average Height of a House Roof

The average height of a house roof is around 9-10 feet. However, the height of a roof can vary from house to house–some buildings feature flatter structures, while others have small slanted roofs.

Those who design the houses (e.g. architects) are generally the ones who determine roof height, and the final decision is often down to style choices. In many residential areas, all roof heights might be the same to create a uniform look.

When considering how tall the average roof is, you must consider the tallest point of the roof rather than the shorter sections. In many cases, the most elevated part is in the middle. However, some roofs might be slanted to the side. In this case, the tallest part of the roof would either be to the left or right.

Here’s Why the Height of a House Varies

Now that you know the average heights of different houses, you might want to know more about why they can vary so drastically from house to house. One simple explanation is that roof height often differs depending on the style and location of the home.

To learn more about why the height of a house can vary greatly, read on below.

Roof Heights Vary

As I’ve briefly mentioned, roof heights often vary from house to house. Since the roof of a home can significantly change its overall height, it’s essential to consider roof height when considering how tall a house is.

As you can imagine, a house with a flat or almost flat roof will likely be shorter than one with a taller roof. In some neighborhoods, all homes might have the same sized roofs. In other communities, the roofs on houses could vary.

Although the average roof height is 9-10 feet, roofs on houses across the country and the wider world can come in many different heights, shapes, and sizes.

Different Regions Have Different Laws/Rules

Another factor to consider is laws and regulations. Some regions might have specific rules regarding the minimum height a ceiling of each story should be. They might also have rules regarding how tall a house can be.

For example, Washington D.C. has strict rules regarding house and business building heights. According to the National Capital Planning Commission (NCPC), residential houses in D.C. can be no taller than 90 feet. In cases where a residential street is between 60 and 65 feet, a house can be no taller than 60 feet tall. Of course, most traditional houses don’t reach these heights, so this likely isn’t a big issue for most residents of D.C.

Still, it’s essential to understand that different regions and countries have various construction height regulations, which can be one reason why some houses are shorter or taller than others.

Foundation Heights Differ

The height of house foundations can also differ, which is another reason why some homes sport different heights. If a foundation is exceptionally tall (i.e., there are many steps you need to climb to get into the property), the house is likely to be taller than the average house.

Foundations are an essential part of any construction because they support the weight of the building. They also promote insulation (keeping the heat in when it’s warm and keeping the cold out when it’s cooler). Because of their importance, you’ll find foundations on all houses.

And since the structure of these foundations often differs, house heights can vary, too. Generally, a residential foundation should rise at least 4-6 inches above the soil. However, some houses may have foundations that are taller than this.

The taller the foundations rise above the soil, the taller the overall house will be.

People Have Different Preferences

Another reason houses vary in height is that homeowners have different preferences. While some people want to build homes with shorter ceilings and flat roofs, others might want to have tall roofs and ceilings.

When planning a house, it’s essential to consider all the measurements. If you’re creating a vision for your home and working with designers and architects to fulfill that vision, they’ll need to discuss your preferred measurements for walls, ceilings, and the roof.

For example, many old houses (such as Georgian-style houses) are taller because they have taller ceilings (particularly on the lower floors). That’s primarily because people liked the idea of taller ceilings many years ago. However, nowadays, smaller, more practical constructions are being favored.

How Tall Is a Garage?

A garage is around 8 feet tall in most cases, but it can be slightly less than this (or more). Generally, garages are shorter than the rooms inside houses because they’re primarily used for storage.

It’s rare for a garage to be smaller than 7 feet tall because it would be more challenging to fit tall vehicles (or even tall people) through the entrance. People with tall cars might want to consider a tall ceiling for their garage.

Some garages can be as tall as 10 feet, so the exact height of a garage can vary. Like with houses, there is no specific height for a garage. However, it’s good to know the general height range, which is between 7 and 10 feet tall.

In some cases, the garage will be the same height as the first floor of the home’s interior. In other cases, it will be smaller.

The Garage Door

It’s also important to consider the height of the garage door. While a garage can be as tall as 10 feet, the door will often be shorter than this. If you look at most garages, you’ll notice the door doesn’t come up all the way–there are usually a few free inches at the top above the garage door.

Many garage doors are as small as 7 feet tall. If a garage is 8 feet tall, the door may be around 7.5 feet tall. However, it can also match the structure’s height to a T.

Can Each House Story Have Different Heights?

Each house story can have different heights. The height of each floor will depend on personal preference and design choices. In certain instances, the lower floor might have taller ceilings than the upper floor. However, in many cases, all house stories are the same height.

It’s also possible that a 3-story house would have a shorter ceiling on the top floor. It all depends on the style of the home, so it can vary widely.

Some people like to have tall ceilings downstairs because it gives the space a more ‘free’ feel. For example, a living area with a tall ceiling will feel more open than a living area with a shorter ceiling.

People who like to feel cozy would generally prefer shorter ceilings both downstairs and upstairs.

What Is the Best Ceiling Height?

The best ceiling height is around 9 or 10 feet tall for most people because it’s not too short but not too tall, either. Most average homes have a ceiling height of around 10 feet. If a ceiling is shorter than 9 feet, it can make the home appear smaller.

However, the best ceiling height can also depend on your personal preferences. For some people, the best ceiling height is 12 feet because they like the space of tall rooms. For others, 8 or 9 feet might be better because they want to feel cozier.

Like many other things in life, there isn’t one specific ceiling height that’s best for everyone. You should consider your style and preferences when determining what ceiling height is most appropriate.

Are House Heights Different by Country?

House heights are not different by country (for the most part). However, certain cultures might have different preferences and stylistic choices, which could make their houses slightly taller or shorter than ones in other places. However, it’s normal for most homes to be similar in height.

For example, the average ceiling in a U.K. home is around 2.4 meters (8 feet) tall. In the U.S., the average ceiling height is about 8-10 feet tall. These heights are generally the most comfortable for most people, which is why most countries have houses with these ceiling measurements.

And since the ceiling heights are the same in most countries, the house heights are similar too. But as mentioned earlier, you also have to consider foundations and roof height.

How Tall Are Front Doors?

Front doors are usually around 6.6-8 feet tall. In most cases, front doors are not as tall as the ceiling. The specific height of a front door will depend on the height of the walls and ceilings on the bottom floor. The taller the walls, the taller the door should be.

How Tall Are House Windows?

Most house windows are the same height as the front door, around 6.6 – 8 feet tall. If the top of the window isn’t aligned with the top of the front door, it will look unbalanced. Although windows should be aligned with the top of the front door, they don’t need to align with the bottom.

For example, many windows don’t reach the bottom of the wall (although some do).


Houses with the same number of levels are usually the same height. Here are some essential things to remember regarding the height of houses:

  • Most 1 story houses are around 12-15 feet tall.
  • Most 2-story houses are about 18-25 feet tall.
  • Most 3-story houses are approximately 30-45 feet tall.

One of the most important elements to consider is roof height – while some houses have flat or semi-flat roofs, others have tall slanted ones. These variables will all affect the overall size of a home.
