Bed sizes in the United States
It's often difficult to figure out what size bed and mattress is best for your family. For a bed with two people sleeping in it is it better to get a queen or a king? Is full too small? Why not a California king? Should you get a single or a single XL for your child?
What bed size is right for you?
Usually it's recommended to get the biggest size of bed for a particular room. However, we think it's important to use past experience to figure out which size bed to buy. In general people are more disappointed by getting a bed that is too small rather than too large.
It's important to leave at least 2 feet on all sides of the bed so that navigating your room is not too difficult. All doors and drawers near the location of your bed should also be measured to make sure they don't collide.
What bed size is right for your sleeping arrangement?
You should also keep in mind your sleeping arrangement and what is important for you when choosing your bed size. If you sleep with a partner regularly then perhaps getting a larger bed will be better for your sleeping habits. Likewise if you need more space as you sprawl out and sleep it makes senses to get a larger bed size.
However, if you like to sleep alone and would prefer more space in your room for activities, then we'd recommend getting a smaller bed. The decision of which bed size to buy is partly preference and we always recommend to get the size that fits your lifestyle.
What is the difference between bed and mattress size?
Any time a shop speaks of the size of the bed it is safe to assume it is actually the size of the mattress. The physical size of the bed frame will usually be slightly larger. For example a US queen size bed frame which is 60" x 80" accommodates a mattress of that size and the size of the bed frame is larger.
The dimensions of a bed also depend on the type of bed you buy. For example, a metal bed and a wooden bed for the same size mattress will have different dimensions.
When buying a bed and mattress, the bed size needs to be matched to the mattress size. You also need to make sure the bed frame is suitable for your bedroom.
