We spend about 30 percent of our lives in the bedroom. This gives us the measure of how important it is to have a comfortable bedroom with adequate measurements.

Standard Bedrooms Size

Bedrooms Size and Dimensions

When distributing any house plan, we must know what the different types of bedrooms are, how much a standard room should measure, and the best way to distribute your furniture. 

To determine  how many meters a room should have , you also have to think about the needs and tastes of each family or tenant.

Bedroom Types

Three types of master bedrooms can be considered:

  • Staff bedroom.
  • Double bedroom.
  • Honeymoon suite.

From these 3 fundamental variants, others are derived, among which, you could review, examples of BEDROOM PLANS with bathroom and dressing room.

Personal Bedroom Size and Dimensions

Small bedroom, with the function that a single person can sleep in it with privacy and comfort. It is also usually a space to carry out hobbies and study. It can be considered as a small, youthful or children’s bedroom.

In personal bedrooms, it must be possible to locate a personal bed , at least one nightstand, and a minimum volume (1.0m³) for storage of clothing and necessary objects. It should also include (although it is somewhat more optional), space to locate a study table with a chair .

What is the Minimum Bedrooms Size?

By international regulations, a minimum of 6.5m2 of usable area is considered. However, to achieve greater functionality, comfort and versatility, a useful area between 7.0 and 9.0 m2 should be considered.

The single bedroom must not have any side less than 2.10m, among other factors, for reasons of proportion and psychological comfort.

Many times, children’s bedrooms with loose measurements end up being their own youth bedrooms or double bedrooms. Proper design planning can save resources in the future.

Windows Area

The minimum area of ​​the windows may vary depending on the country and its prevailing climate. As a general rule, a minimum window area of ​​10% of the floor area of ​​the room can be considered. This will allow for minimal airflow and natural light.

At the same time, the size of the window must work when necessary, as an emergency exit, for housing on the second level or more.

Measurements of Beds, Cribs and Bunk Beds


The bed is the main piece of furniture in the bedroom and is a basic element to establish how big a room is. The design and distribution of furniture and circulation must be based on the best position of the bed and its measurements.

Queen Size beds, with measurements of 2.00×1.50 meters, require bedrooms with minimum measurements of 2.70×3.60 meters.

The area for the crib must consider average measurements of 135×75 cm (size of the crib mattress), plus a few centimeters, due to the thickness of its structure. Any double bedroom should have enough space for a cot.

Bunk Beds

The bunk beds can have average measurements of 90 cm wide and 190 cm long. In the case of its height, the ceiling of the bedroom should be greater than 2.50m so that the person can safely accommodate it.

How Big is a Standard Bedroom

There are three basic types of bedrooms and each one requires respective BED MEASUREMENTS, types of furniture, circulation areas, and storage. All this must be taken into account when making the house layout and design.

When analyzing the spaces of a normal home and its characteristics, it is advisable to geolocate by country, and even by region. 

The normal size of a bedroom will not be the same in countries like Mexico or Argentina, as it is in the United States, Spain, or Asia. Social and economic conditions have a significant influence on this.

It must also be taken into account, to what TYPE OF HOUSE the bedroom would belong, if it is a house located in the countryside or in the center of the city.

Let’s do an analysis by country, using different examples of BEDROOM PLANS WITH MEASUREMENTS .

How big is a Standard Bedroom in the United States?

The United States is such a large and diverse country that it is a bit risky to define an average bedroom size. 

With different climates, influence from different cultures, large numbers of immigrants, and vast differences in the purchasing power of its general population, American homes can be very different in design, style, and size.

Larger houses and apartments, urban and suburban mansions, tend to have larger rooms than typical suburban houses for the lower and middle classes. Even in condominiums, apartments in medium-standard buildings, rental apartments, or cabins, there can be very different useful surfaces.

However, a large portion of homes in the US have two basic bedroom types, based on square footage: the master (owner’s) bedroom and the standard or smaller bedrooms.

How big is a Main Bedroom in the USA?

The main bedroom of houses in the USA usually has between 18 and 20 m2 of usable area. Of course, in larger houses, this area tends to increase. It must be considered that the bedroom is usually smaller than a living room.

How Big is a Room in Germany

Germany is one of the European countries (and in the world) with the greatest development and social welfare, and this also affects housing planning. With a high economic level, it is easy to understand that the bedrooms and homes in Germany are spacious compared to other latitudes.

It is fair to point out that the height of Germans (and Europeans in general) is above the world average, which influences the size of the bed, the circulation around it and the furniture in general.

The bedrooms usually have a wardrobe, a bed and a nightstand, as essential furniture. They also usually include a secretaire, a makeup dresser and space for seats. The bathroom and dressing room are attached to the double bedroom.

The Germans consider that the space of the room must have at least 12m² of useful surface, regardless of the type of bedroom. Even for the children’s rooms, they take into account 12m² as a starting point in the design, including the play area.

The shortest wall of the bedroom is placed at 3m, in order to place a generous closet. In the bedrooms with a dressing room, they suggest increasing by 6 to 8 m2, for a total minimum area of ​​the room with a dressing room of 18m².

Single Bedrooms Size and Minimum Dimensions

Considering a single room, with a single bed (1900x1000mm), 2 bedside tables (500x600mm), and a wardrobe (600mm wide), we have that the length and width of a small room should be 2600 x 2800 mm.

Minimum Measurements for a Double Bedroom

For double and matrimonial bedrooms, the minimum measurements would be 2600 x 3800mm, considering a Queen bed of 2000x1500mm. In this way we already know how many square meters a double room has.

How Many square meters should a Bedroom have, Summary

It can be seen that there is variety and similarity in the measurements that a room should have in each country. There must be an interpretation, based on the characteristics of the population, the climate, the culture and the economic development achieved.

From the architectural point of view, the sizes, the types of HOUSES, and the measurements of the beds, are essential to establish how big a room is. Personal tastes must play a definitive role.
