Welcome to our bedroom size guide including standard room dimensions and measurements for different bedroom designs.
The bedroom is a personal space in the home. 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
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.
Average Master Bedroom Size
The master’s bedroom or the primary bedroom 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.

Standard Bedroom Size
Standard bedrooms are often occupied by the children or the teenagers in a home, thus making them smaller than the primary bedroom. These rooms are also often the ones turned into home offices or study and even home gyms or guest rooms.
Depending on what the homeowners are choosing this room for, the standard size can range between 10 ft. x 10 ft. to 12 ft. x 12 ft.
It is 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.
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. 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 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.

Standard Bedroom Door Size
Standard bedroom door sizes have a width of 24 to 28 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.
