Should I Buy a Twin or Twin XL Mattress?
Deciding between a twin vs twin xl mattress is primarily a matter of who will be sleeping on the mattress and the size of the room that the mattress will be in.
Twin mattresses are good for:
- Kids: If you are buying the mattress for a child transitioning out of a crib, then a twin may work wonderfully for years to come.
- Saving Money: Standard twin mattresses are the cheapest beds you can find.
Twin XL mattresses are good for:
- Guest Rooms: If you are getting it for a guest room and the guests are taller adults, they might be more comfortable on a twin XL.
- College Dorm Rooms: College students typically sleep on twin XL mattresses.
- Single Adult Sleepers: Even though it’s narrow, adults and single sleepers can fit on a twin. A twin XL will be more comfortable, though, to account for extra height.
- Split King Setup: If you and your partner decide you want to go the route of combining two twin mattresses in a king or split king frame, so you can each have separate mattress densities or mattress firmness, then the twin XL is perfect.
Twin vs Twin XL Buying Considerations
The most common places twin beds are used is in children’s rooms, dorm rooms, guest rooms, and master bedrooms; quite a few places if you stop and think about it.
Establishing what size will work in a room requires a little measuring unless the room is very large. The standard determinants are a minimum of 30 inches of space around three sides of the bed for ease of movement. The last thing you want is a bed too big to shuffle around.
In the case of the twin vs. twin XL, you are primarily assessing the length of the bed and a few inches can make a difference in how well it works in a room.
The twin is generally cheaper than a twin XL. This is true of bedding accessories such as sheets, pillows, toppers, and bed frames as well.
If you are on a budget and the length doesn’t matter, you may want to go with the standard twin. If the cost difference, which is generally not substantial, is not a concern, you may want the extra length and to go with a twin XL.
Shopping for a child? Look for a Twin XL if you’re anticipating a growth spurt; the extra length can help prevent taller individuals from outgrowing their mattress quickly.
Standard twin mattresses are easy to come by along with standard twin bedding. When you move up to the twin XL, things get a bit more difficult.
Many, but not all, mattress manufacturers make a twin XL, and bedding availability is varied. Some linen companies offer twin XL sizes and others do not. So, if you don’t want the extra work of finding who carries those perfect organic sheets in a twin XL, you might go with the standard twin.
Durability and Longevity of Use
One further consideration is how long you want the bed to be viable. If you want the bed to last your child through their adolescence and beyond, you may want to just start out with a twin XL, so when your basketball-playing, 6-foot 2-inch son needs a longer bed, you don’t have to buy a new one.
Maybe you are buying a mattress for your daughter who is only 5-foot 2-inches and could get by with a standard twin, but you plan to move that bed to the guest room when she leaves for college. Then, you might want a twin XL, so it can be used for other adult guests who would be more comfortable in a longer bed.
Deciding between a twin vs. twin XL mattress? The only difference is five extra inches of length.
Which will work best is predicated on several variables including the size of the person sleeping on the mattress, the room it will be used in, if the cost difference is worth it, availability of bedding, and how long you plan to use the bed.
Having size options is a great way to find a mattress that is more comfortable, especially for the taller individual.
