According to the Better Sleep Council, choosing a bed that is too small is one of the most common mistakes people make when buying a bed. When considering king size beds versus queen size beds, the only real difference is the size. Sleeping comfort and the size of the bedroom are two factors that influence the decision on what size mattress to buy.
A king size mattress is the largest available. The queen is the second-largest choice. Actually, both mattresses are the same length, but the king size is wider. King size mattresses are 76 inches wide by 80 inches long. A queen size mattress is 60 inches wide by 80 inches long.
For people who want maximum personal sleeping space, a king size mattress is a good choice. For many couples, the extra space is the difference in being able to get a good night's sleep. A king size bed is the closest a couple can get to the individual space of a twin size mattress. For those who prefer closer quarters, consider a queen size mattress.
The size of a king size bed can be a problem. In some cases, it may be too large to move through halls, corridors and doorways. In a small bedroom, a king size bed may simply take up too much space. Before buying a king size bed, take measurements and make sure the bed can be moved and fits the bedroom space. People facing space constraints may have to go with a queen size bed.
The right size bed can have a real impact on how well you sleep. The National Sleep Foundation notes the importance of having a comfortable mattress and pillows in getting a good night's sleep on a regular basis. People who tend to be "sprawlers" in their sleep will benefit from having a larger mattress.
For taller people, the "California King" might be a good choice. At 72 inches wide and 84 inches long, it is a little narrower and longer than a standard king. Though king and queen size beds are designed for couples, large individuals and people who like to spread out when they sleep may feel comfortable in a queen size bed.
