The smallest suggested bedroom size (clear space) should be 100 sf (10 ft x 10 ft) with a closet that has ample space to store clothing. At minimum give an addition 8-10% of square footage to devote to bedroom closet space that is at least two (2) feet in depth. That 100 sf bedroom should at minimum have a closet that is 4 ft x 2 ft (8 sf). The closet depth of two (2) feet is in addition to width or depth. If the closet is designed within the bedroom clear space (inside the actual bedroom space), there must be enough room to accommodate the closet depth. A bedroom has to be at least 12 feet 4 inches (clear space) in either width or depth to allow for a minimum 10 feet room either way.
So why is it necessary to place these rooms in a cool and isolated space? We tend to spend a lot of time in our private domain (aka bedroom). Privacy, quietness, and comfort are the driving forces behind this design philosophy. If a bedroom is to be your get-a-way or sanctuary, you would definitely want those room attubutes.
Size and Shape
The size of a bedroom is dependent upon who occupies the space and how much furniture will be in the room. An average to midsize bedroom (i.e. kids, nurseries, and guest rooms) is somewhere in the area of 100 to 200 sq ft. Ideal sizes would include the following:
Midsize and large bedrooms generally start at around 200 square feet in size. Bedrooms of this scale are usually reserved for master sleep quarters. In large or estate homes, the secondary sleeping rooms rival that of smaller home master beds. Ideal dimensions for these rooms include the following:
