A double bed is 53 inches wide and 75 inches long. The name can be misleading, as you may think that it's twice the size of a single bed. However, the double bed is only 15 inches wider than a single bed.
At 53 inches wide, each person only has about 26 or 27 inches of space in which to sleep. This may be enough space for those who prefer to sleep on their sides and who don't move around much in their sleep. However, stomach and back sleepers, those who like to sprawl out when sleeping or those who toss and turn may have a difficult time sleeping with two people in a double bed. Additionally, the length of the bed may make it a poor choice for tall people.
Double beds are popular choices for teenagers and single people. The extra space can seem more luxurious. Additionally, parents should consider a double bed for even younger children, as it gives more space for the parent to lie down and read a bedroom story.
While those who have small bedrooms may have to make do with a double bed, others should consider the alternatives. At 60 inches wide and 80 inches long, a queen bed leaves more room for two people and is a better fit for tall people, while still fitting in most rooms. If your room is large, a king bed or California king bed offers the same amount of space as two single beds, while allowing a couple to share a bed.
