It is sometimes easy to forget that the bedroom is used primarily for sleeping, and it should therefore be designed with comfort in mind. Designing a bedroom should focus on efforts to make the space comfortable and usable, and any decorations should promote a calming atmosphere that will help the homeowners fall asleep easily. Perhaps the most important consideration when designing a bedroom, however, is the need to measure carefully to ensure the furniture placed in the room does not make the space feel either cluttered or too cavernous. Furniture and fixtures should all be chosen carefully for aesthetics and functionality.

Of course, most people use the space for more than just sleeping, so functionality is vital when designing a bedroom. If the room does not have adequate closet space, a wardrobe can be used, but it must be placed carefully in the room to ensure it does not take up too much space. A corner is a good place for a tall wardrobe, but care must be taken to ensure the door or doors of the wardrobe can open freely without obstructing walking paths or colliding with other pieces of furniture. In some rooms, smaller, wider pieces of furniture may be more appropriate.

Take advantage of available light when designing a bedroom and note where the sun moves across the room through windows throughout the day. Try to avoid putting the bed in the direct path of the sun's light, but make sure plenty of light can stream into the room. Heavy curtains are a good choice if the homeowner frequently takes naps during the daytime or sleeps late in the morning, but remember that heavy curtains that do not allow light to pass through will keep the room dark even when it is light outside, which can promote oversleeping.

Choose wall colors carefully to promote a cozy atmosphere. Subdued colors are usually best, though this will largely be a matter of preference when designing a bedroom. Think about the color of the floor and of the furniture in the room, and try to choose a wall color that is complementary to these items. Bright colors may not be exceptionally relaxing when the homeowner is trying to go to sleep, and colors that are too dark may make the room feel uncomfortable and dreary. Subdued colors with brighter accents work well, and wallpaper with designs that are not too busy can be relaxing.
