Choosing the right mattress size comes down to a simple formula – buy the largest size that fits your bedroom, budget and the length of the tallest partner. In general, the bigger the mattress the more it will cost.
Twin or Single (39 wide by 75 inches long)
This size is designed for one person and is usually used by teenagers and children. Many people use them as daybeds or hideaways. A cheap twin mattress is often easy to find.
Extra Long Twin (39 inches wide by 80 inches long)
The extra length means they can sleep a larger person and are a ideal for university dorms.
Full or Double (54 inches wide by 75 inches long)
The length of a full sized mattress is the same as a twin and this can be not long enough for many adults. While there is extra width than a twin, it doesn’t actually leave that much room when two adults sleep on them. They are a cheaper alternative to the larger kings or queens, and can fit into small rooms as a guest or spare bed. It is often easy to find a cheap double mattress.
.
Queen (60 inches wide by 80 inches long)
This is the most popular type of mattress. The extra width and length makes them ideal for couples wanting a roomy and comfortable slumber.
King or Eastern King (76 inches wide by 80 inches long)
A king sized mattress is the equivalent of two twin beds. There is plenty of room and are great for tall adults. The larger size however, can mean they are difficult to move through the house or won’t fit on small bedrooms.
California or Western King (72 inches wide by 84 inches long)
This is the longest type of mattress that is available but is narrower than a normal king. They are ideal for tall adults who need the extra length.
