What is the typical square footage of a bedroom? A bedroom’s size depends on several factors. The size of your home, the type of bedroom you want, and the country where you reside.

With average, we’re referring to US dimensions since most of our readers live in America. We’ll also review the average bedroom sizes in other countries. When the country isn’t specified, assume we’re talking about US standards.

Average Bedroom Size

Average bedroom size depends on the type of room. The average size of a child’s bedroom is not the same as a typical master bedroom. For this reason, we can’t estimate or calculate average bedroom sizes. 

What we can provide are bedroom size ranges. The size of a bedroom scan be 50 square feet in a small home to 500 square feet in a large home. Since tiny homes are becoming more popular, the average bedroom size is becoming smaller. 

With such an extensive range, it’s hard to determine overall average bedroom size. So, we’ve broken it down into types of bedrooms, countries, and bed sizes used for each room.

Average Home Size In The US

Average Home Size In The USView in gallery

Average home size in the US is roughly 2,000 square feet. The average bedroom size is 200 square feet. Your bedroom size depends on the size of your home. You don’t want your bedroom to be bigger than your kitchen or living room. Finding a balance is important.

There is a formula that you can use. It’s ten percent of your home blueprint design.

The average square feet of a bedroom is ten percent of your home’s size. You can use this formula when deciding on a home. 

Your bedroom is subject to your taste and preferences. Not everyone wants an average-sized room. Some want a tiny bedroom and large living room, while others like the opposite. 

Average House Size In Other Countries

Average House Size In Other CountriesView in gallery

The US has one of the biggest average bedroom sizes worldwide. The only country ahead of the US is Australia.

Although we can’t access statistics on average home sizes in all countries, we can tell you the average house size in most countries. This is, on average, counting both city (which are smaller) and rural (which are larger) houses. 

In Hong Kong, the average home size is less than 500 square feet. China has apartments over 800 square feet, yet the average home size is 645 square feet (see below).

Average House Size:

  • Russia: 613 sq dt
  • China: 645 sq ft
  • United Kingdom: 818 sq ft
  • Italy: 871 sq ft
  • Sweden: 893 sq ft
  • Japan: 1022 sq ft
  • Spain: 1044 sq ft
  • Germany: 1173 sq ft
  • France: 1205 sq ft
  • Greece: 1356 sq ft
  • Denmark: 1474 sq ft
  • Canada: 1948 sq ft
  • United States: 2163 sq ft
  • Australia: 2303 sq ft

Use the one-tenth rule to determine the average square feet of a bedroom in a country. Divide the home measurements by ten to discover the average. Some will use less or more room for their bedroom. 

Culturally, bedrooms vary in size. A studio apartment may not have a separate bedroom, while a farmhouse will have large bedrooms. Then you go to Japan, and you’ll notice minimalist furniture, which makes the rooms look bigger. 

Size Of The Bed

If your bedroom doesn’t have an owner but has chosen a bed, you can use that to find out how big it needs to be. Another formula is The Golden Ratio, otherwise known as three to one. 

A queen bed is 33 square feet, so that the standard room size would be 100 square feet. Most bedrooms are 10 feet by 10 feet or 8 feet by 12 feet. Just remember, 3:1, and you’re all set. 

The formula is a rule of thumb and can help optimize space. Most people prefer larger rooms. The larger the bedroom, the better, as long as it doesn’t take away from other rooms.

Average Master Bedroom Size

The master bedroom is the biggest bedroom in a home. It belongs to the owner of the house on most occasions. It also usually has a king-size bed, which means that space needs to be bigger than if you had a full-size bed. 

The average square footage of a master bedroom is between 200 and 300 square feet when the home is between 2,000 and 3,000 square feet. A standard master bedroom size is 14 feet by 16 feet. A bedroom of this size can accommodate a king-size bed, leaving room for furniture. 

You can exchange your master bedroom with the living room or family room if you want a larger bedroom. The standard living room is over 300 square feet and 16 feet by 22 feet.

Kids Bedroom

Kids’ bedrooms are often smaller than other bedrooms. In fact, often, they are as little as one-half or even one-third of the size of the master bedroom. Most of the time, a kid’s bedroom will have a twin-size bed. 

Because of smaller bed sizes, the average size of a child’s bedroom will be between 50 and 150 square feet. It’s not uncommon for home offices to be turned into kids’ rooms, giving them less room. 

If your children share a room, you can save space with bunk beds. Kids older than five enjoy bunk beds, and they are safe to use. This way, you won’t have to add on when children are sharing one room. 

Average Guest Room Size

Most people don’t put too much thought into the size of their guest room. They use the room that is available. But a guest room is bigger than a kids’ room but smaller than a master bedroom.

A guest room typically has either a full-size bed or a queen-size bed in it. The room itself is between 100 and 200 square feet. But unlike other bedrooms, the size of a guest bedroom varies greatly. Some houses don’t even have a guest room.

Should your home have over one extra bedroom, design the larger bedroom. You can use this as your guest room. If you have two extra rooms, put some of the nicer things in the smaller bedroom so that both guests will have equal amenities. 

How Small Is Too Small?

If you don’t more space, you’ll want to make each room as small as possible. Get the smallest bed that you feel comfortable and make sure it takes up only half of the room.

So if you get a full-size bed, which is under 30 square feet, it wouldn’t bode well in a room under 60 square feet. A room that is 8 feet by 8 feet would be small for a room with a bed this size, but can work in a tiny house. 

There are other options, like sleeper sofas and futons that fold out into a bed. This way, there is more floor space during the day, and during the night, there is more bed space. You know what they say, “more bedroom equals less bedroom.” 

Cost Of Adding A Bedroom

The expense of adding a bedroom to your home depends on its square footage. The range is between $50 per square foot to $300 per square foot. This ends up being somewhere between $10,000 and over $100,000

A master bedroom will cost over $50,000, while a smaller room will be $15,000. Each contractor charges differently, so you’ll have to contact the company you have in mind to get a quote.

The state you live in is a factor. Arkansas and Mississippi have the cheapest home construction rates, while Hawaii and California have the most expensive. You can estimate your state’s cost by the cost of your home.
