Bedroom Size (Dimensions Guide)

Welcome to our bedroom size guide, including standard room dimensions and measurements for minimum, small, large, kids, and guest room layouts.

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

There are different kinds of bedrooms, small and large; some serve the sole function of being just a place to sleep, while others have space for bathrooms and large closets. No matter how big or small your bedroom is, it is important to keep it proportionate with enough space to move around easily. 

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

Average Bedroom Dimensions

An average bedroom has a bed, a wardrobe, a dressing table or a study desk, and two or a single bedside table or locker. With that, the average bedroom size is dependent on the size of your bed. 

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. 

Size of Average Master Bedroom

The master bedroom, or primary, has the most extensive square footage room in the house. It can accommodate a bigger bed — a queen or a king and could likely even have an en-suite bathroom. 

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. Check out our master bedroom size article for a more in-depth guide.

Standard Child or Teen Bedroom

Standard 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 use 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 plan 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 Suite Dimensions

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

A California King is the biggest bed size outside the realm of custom mattresses, with a size of 72 x 84 inches.  If you plan to have that for your bed, a room of 12 x 12 feet would fit it nicely, but you can go bigger to accommodate a walk-in closet and an en-suite bath. 

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

Large bedroom suites with floor space for 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 spacious as 22 ft. by 20 ft. 

Small Bedroom Floorplan 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 is 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 Space Needed

For providing the minimum bedroom size, we decided to base it on the standard bed sizes: a twin, a double, a queen-size bed, and a king-size bed. 

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 Square Footage 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 with 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 floor plans with higher ceilings than the typical 8-foot height can accommodate 350 to 420 square feet.

Suite Master. A more luxurious master than your standard version due to the larger square footage and added features such as a lounge, fireplace, private balcony, etc.

Split Master. The split master is for couples who prefer separate sleeping areas. This design plan usually will have its own bathroom and closet area.

Dual Master. Similar to the split master, the dual master plan will have each with its own adjoining room but this time share the same bathroom and closet, usually having floor plans with identical square footage and design.

Garden Master. As the term implies, this master is found at the ground floor level and can access an exclusive garden or outdoor space.

Loft Master. The loft master is located in a loft space or the attic. The location provides unusual room shapes and architectural features such as sloping ceilings or exposed beams.

The standard bedroom size for a guest room is 100 to 200 square feet with minimum dimensions of 10 feet by 10 feet. However, there are many considerations when sizing up your guest room, such as the desired level of comfort, the available space, the average number of guests, and other features required for the guest room.

Standard Guest Room	100 to 200	10 x 10
Family Guest	200 to 300	12 x 12 (min)

Multipurpose Guest. Another flexible space can be a home gym, media room, or craft area when not in use. A sofa can be converted into a bed, or a Murphy bed can be easily drawn down when needed. 

Standard Kid’s Room Size

Infants and Toddlers	100 or more	8 x 12.5
Preschoolers and Elementary	120 to 150	10 x 12

Standard (Average U.S. Kids)	100	10 x 10

Infants and toddlers. The recommended size of 8 feet by 12.5 feet accommodates a crib or toddler bed, changing table, and other furnishings.

Preschoolers and Elementary. A twin or full-size bed can be accommodated, along with a closet, play area, and storage for toys. 

Middle and High School. The recommended size of 12 feet x 12 feet provides enough space for a full-sized bed or a twin bed, closet, study desk, television, and bookshelves. 

Tip: Beds are best positioned diagonally from the entry door, at the far corner, against either of the two walls. This bed orientation allows the sleeper to have a full view if someone enters a the space. 

Considerations When Determining the Best Room 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, light fixtures, and windows, and determine how to plan around these elements. 

• When planning for the depth of closets, a dresser, wardrobe, or cabinets, 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 Door Size for Bedroom

Standard 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 floor plans 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.
