It is a place where we can just be ourselves, a place away from the outside world where we can relax and zone out. We spend one-third of our whole lives sleeping, thus making the bedroom one of the most important places in our lives. 

There are different kinds of bedrooms, small and large; some serve its sole function of being just a place to sleep while other bedrooms contain a person’s whole life. No matter how big or small your bedroom is, it is important to keep it proportionate with enough space to move around in easily. 

Here we guide you through different room dimensions to assist you with your home building or renovations.

Average Bedroom Size

Since a double size bed is usual for standard rooms, the average room size to accommodate a double size bed, two bedside tables, and a small wardrobe is 9 ft. by 9 ft. and 6 inches. 

For a room to accommodate a whole wall wardrobe and a desk or a dressing table, a space that is 10 ft. 6 inches by 11 ft. and 6 inches would be perfect. 

Average Master Bedroom Size

The average size for a primary bedroom is 15 ft. by 15 ft. Still, it could be bigger to fit the homeowner’s needs, whether additional pieces of furniture like a chaise or even a two-seater sofa or extra closet storage units.

Standard Bedroom Size

Standard bedroom sizeStandard bedrooms are often occupied by children or teenagers in the home, thus making them smaller than the primary bedroom. These rooms are also often the ones turned into home offices or a study and even home gyms, or guest rooms. 

Depending on what the homeowners are using this room for, the standard size can range between 10 ft. x 10 ft. to 12 ft. x 12 ft. 

It’s always smart to decorate around the biggest furniture you are planning to designate this room for. If you use bunk beds, a 10 ft. x 10 ft. twins’ room will look bigger and have more space to add furniture. Situating the bunk beds near the wall could make room for two study desks with chairs. 

Large Bedroom Dimensions

Ultimately, the size of your bedroom would depend on the size of your house. The dimensions for the primary bedrooms could seem minuscule for you. Besides the house size, the size of the bed would also be another factor.

There should be a 36 inches clearance space around the bed to be able to move about comfortably.  All in all, amounting to a room of about 14 feet and three inches in width and 10 feet in length. 

Large rooms with a sitting area, a comfort room with a tub and a shower, and a walk-in closet with built-in parallel shelves and extra storage could amount to space as ample as 22 ft. by 20 ft.

Small Bedroom Dimensions

Small bedroom dimensions are dependent on the size of small single beds. The average size of a small single bed used by kids and for studio living is 3 feet in width and 6 ft. 2 inches in length. A longer size for taller people has 3 feet in width and 6 ft. 8 inches in length. 

A small room with a single bed can have an area of 10 feet 2 inches in length and 8 feet 6 inches in width that would fit a single bed, a small wardrobe on the foot of the bed, and a study table or vanity on the side—leaving enough space for a beanbag or two. 

Minimum Bedroom Size

For a twin-size bed with dimensions of 38 by 75 inches, a minimum room size of 7×7 or 49 square feet is most appropriate. 

A double bed that is 53 by 75 inches can be accommodated in a room with a minimum size of 9 x 9.6 or 85.5 square feet. 

For a queen-size bed that is 60 by 80 inches, a minimum room size of 9.6 x 10 or 96 square feet can accommodate it comfortably. 

A king-size bed with dimensions of 76 by 80 inches can fit in a room with a minimum size of 9.6 x 11.6 or 109 square feet. Read more about our guide to bed sizes here.

Standard Bedroom Size For a Master Bedroom

While the average size for a master bedroom is 225 square feet, the ideal size can range from 200 to 250 square feet, which can easily fit a home that has around 2000 to 2500 square feet.

Larger-sized homes can accommodate larger master bedrooms with an area of 300 to 350 square feet. More expansive master bedrooms with higher ceilings than the typical 8 feet height can accommodate 350 to 420 square feet.

Considerations When Determining the Best Bedroom Size 

• Know the number and type of users. As a rule of thumb, 70 square feet of space is needed per person in a room. 

• Determine the needs of your guests. Is a study desk or kitchenette needed? These added amenities affect not only the size of the area but the layout of the furniture as well. 

• Visualize the bedroom layout. Best to create a floor plan. If there is existing furniture to be used, these should be accounted for at the initial stage of planning. 

• Be mindful of architectural details such as an existing fireplace, beams, doors, or windows, and determine how to plan around these elements. 

• When planning for the depth of closets or cabinets, be sure to consider the door swing. If planning for a tight space, consider sliding or curtain doors. 

• For a flexible guest room, make sure furniture and cabinets are easily moved or stored away when needed. 

Standard Bedroom Door Size

Bedroom door dimensionsStandard bedroom door sizes have a width of 32 inches and a height of 80 inches. This length can accommodate a tall person entering a room with the comfort and hassle of having to stoop.

With this standard height in mind, it is the homemakers’ choice if they want a door broader or longer to integrate with a high ceiling house or whatnot. 

There are also bedrooms with doors that open to a balcony; this opens the avenue for experimentation on door sizes and styles.

Examples are barn doors or French doors that are dependent on the size of your space. For closet doors, the usual size ranges from 24 to 30 inches.
