Average Bedroom Size: By Room Type, Minimum Legal Limit, Size By Country, & Much More!

Compliance with the average bedroom size as per the applicable law matters a lot when it comes to a residential property’s appraisal during sale. If you own a house, the bedroom in it has to be of a specific size to fit the needs of a human being legitimately. Otherwise, the space cannot be listed as a valid bedroom, and that will lower the home value dramatically. Minimally, a legally compliant bedroom at least has to be 70 square feet and not less than that. There are other conditions as well that you will find below in this article.  

What is the Average Bedroom Size?

The average bedroom size in the U.S. is 132 square feet. This number translates into 11 feet by 12 feet. That is the average size for several types of bedrooms. You can use this measurement for your master, secondary, guest, kids’, and other types of possible bedroom variations. If you can secure this much space for your bedroom, you are going to have a luxurious and comfortable experience. This much space is enough for meeting all kinds of normal bedroom needs. 

Note: While comparing townhouse vs apartment, don’t forget to compare bedroom sizes as well. Sometimes, you don’t even get the standard size of the bedroom in such units. So, be careful right from the beginning. 

Standard Bedroom Sizes by Room Type

The bedroom standard sizes vary by room type. For example, it is between 200 and 250 sq ft for a master bedroom, while it is 100 to 120 sq ft for a guest bedroom. For more information, refer to the following table. 

Standard Bedroom Sizes
Room Type	Typical Dimensions	Square Footage	Ideal Bed Size

Minimum Legal & Building Code Bedroom Sizes

For the standard size of bedroom, most U.S. states and local building codes require a minimum of 70 square feet. This is to be considered along with a minimum dimension of 7 feet in any possible direction. 

Furthermore, to be legally counted as a bedroom, the room has to have at least one window for proper ventilation and natural sunlight. And that should follow with emergency egress. Additionally, a closet is also an essential feature in many regions. 

Requirement	Minimum Standard
Minimum floor area	70 sq ft
Minimum horizontal dimension	7 feet
Minimum ceiling height	7 feet (for at least 50% of the room)
Window	At least one fully functional
Closet	Not required in all jurisdictions

Do you know? Many rooms with average bedroom sizes don’t fulfil the minimum requirements set by local building codes. Thus, technically, these structures aren’t categorized as bedrooms in property listings. And that negatively impacts resale prices for all types of houses!

How Bedroom Size Affects Home Value

The average bedroom size directly affects home value. The simple rule is that the higher the bedroom size, the higher the property value will be. In other words, rooms that fulfill or exceed the legal criteria often get sold for higher prices than undersized units. 

Consider the following table touching upon how bedroom features influence the value of a house. 

Bedroom Features	Impact on House Value
Oversized master suite (more than 300 sq ft)	High resale price
Standard bedroom size (100 – 200 sq ft)	Average resale value
Below minimum bedroom size	Negative impact, as no sensible buyer would like to buy it
Additional legal bedrooms	Each addition of a bedroom can increase value by more than 15% in optimal cases.

Point to note: A room that doesn’t even meet the minimum size requirement of 70 square feet and doesn’t have a window cannot be listed as a bedroom. The listing will have to be reorganized if the issue is raised by any interested party upon closer examination.

However, if your bedroom space doesn’t comply with the limits of the law, you can reconstruct the space with professionals. And make the space law-compliant. Then, it can be easily sold for better prices, and the owner will not have to list it by resorting to illegal means. 

Owners of single-family homes must pay attention to these things in advance. Otherwise, the reputation of the property will get spoiled among potential buyers due to misinformation in the listings. 

Average Bedroom Size by Country 

Let’s now explore the average size of a bedroom by country. The following table includes the United States, the United Kingdom, Australia, Japan, South Korea, and worldwide.  

Countries	Ranges
United States	132 to 350 sq ft
United Kingdom	150 to 250 sq ft
Australia	200 to 300 sq ft
Japan	100 to 200 sq ft
South Korea	100 to 200 sq ft
Worldwide	100 to 250 sq ft

Wallinsiders insight: It is crucial to learn about average bedroom size in different parts of the world. That is especially crucial if you want to buy houses in more than one country or you already have properties across different countries that you might want to sell in a few years.

Do you know about this limit across Asia? Urban apartments here typically feature bedroom dimensions from 80 to 120 square feet. The minimum requirement is higher than the minimum requirement of 70 square feet in the United States.  

How to Know If Your Bedroom is Standard Size

It is very easy to know if a room is a normal bedroom size. All you need to do is measure whether it meets standard dimensions, as mandated by law. Its measurement should be 132 square feet or higher to be a valid bedroom, in compliance with applicable laws. 

If you need help with quality assessment, consider hiring a home inspector. However, before you do that, make sure that you go through the home inspection checklist for buyers yourself. That will help you deal with the evaluation process in an informed way. 

Point to note: Many small bedrooms create a facade of being spacious and large. But actually, they don’t even meet the minimum space requirement of 70 square feet. This effect is often created by high ceilings, making the room appear bigger. 

Another way to know if your bedroom is standard size is by having an in-depth knowledge of applicable laws and limits prescribed in them. Being aware of local rules and regulations is important.    

So, if any changes to the law happen, you will know about them in advance.

What Fits in a Standard-Size Bedroom?

Along with these, small furniture pieces can also be fitted within the space as per the needs and preferences of the child. 

Consider the following tips if you want to make the most out of a standard-size bedroom.

• Keep your furniture right-sized or proportional. It will help prevent crowding the floor. Using the right size of bedroom furniture is key to making the space functional and highly mobile. Otherwise, you will have trouble moving in a cramped space.
