For example, in a 12 by 13-foot space, the appropriate ceiling height would be 12.5 feet. The optimal ceiling height in a small space measuring eight feet by 10 feet is nine feet. Natural light lighted rooms are pleasant and cheery, and may even improve our spirits. Ceiling heights should be high enough to allow for this. In general, you want the ceiling to be between seven and eight feet high. Any higher than that and you start to run into problems with air circulation and heat loss/gain. Lower than that and you don't have enough room for beds or chairs. The ideal bedroom size is 40 square feet. Anything smaller and you will feel cramped when sleeping, and anything larger can make it difficult to maintain a healthy lifestyle while living alone. The recommended minimum ceiling height for bedrooms is six feet. This allows enough space for beds without feeling confining. A ceiling between five and six feet high is best if you want to be able to walk around without climbing a ladder or step stool. Anything less than five feet and you will need to make your beds on the floor or use bed rails to keep yourself safe while asleep. There are many options available today for making ceilings look higher. You can buy lighting fixtures specifically designed to go above a normal ceiling and give the room a brighter atmosphere.
