When on the hunt for the best mattress, consider bed size. For a single person with limited space or a parent looking for a bed for their child, a twin or full size mattress could be the best option. Larger mattresses, like a queen or king-size, may not fit in smaller bedrooms, but a twin or full will.
In our article, we outline the difference between a twin and full mattress, including the pros and cons of each.
What’s a Twin Size Mattress?
A twin size mattress is the smallest, most compact standard size available. Measuring 38 inches by 75 inches, twin size, or single beds, are perfect for children’s rooms and an excellent option for children graduating from a crib mattress.
Families with more than one child may find a bunk bed frame or trundle bed a great space-saver, leaving more room for play.
Twin size mattresses, sometimes also called single mattresses, are also a great choice for guest beds and limited living space, like studio apartments or dorm rooms.
Pricing for a twin size mattress ranges between $100 to over $1500. High-end brands charge more since they include exclusive technologies and organic materials.

Recommended Room Space
The best room size to accommodate a twin bed should be 7 feet by 10 feet, allowing room for furniture and space to move around.
- Perfect for kids
- Small, compact size for easy movement
- Bunk bed compatible
- Least expensive mattress size
- Too small for couples
- Not ideal for restless, or combination, sleepers
- May feel too small for some adults
What’s a Full Size Mattress?
A full size mattress, or double bed, measures 54 inches by 75 inches. The full size bed is perfect for single sleepers, from teenagers, college students, and single adults with limited sleeping space. Full beds are also great for guest bedrooms, though it might not provide enough room for couples.
A full size mattress ranges between $500 to $2000 in cost, depending on its features and number of layers. Mattress companies charge more for special technologies and more materials because of the extra comfort they provide.

- Great for teenagers
- Ideal for college dorm rooms and studio apartments
- Good for guest rooms
- More space than a twin mattress
- Not ideal for couples
- Taller individuals may find a full size too short
Best Amerisleep Twin and Full Mattresses
We produce all of our Amerisleep mattresses in seven standard sizes, including twin and full sizes. We highlight some of our more models below, regardless of size, to help customers answer the question of “What mattress is right for me?”
Other Mattress Sizes
If either a twin or full size mattress isn’t for you, other available mattress sizes include twin XL, queen, king, and California king. These sizes could provide more space to accommodate couples and taller individuals.
Twin XL Mattress
Twin XL size mattresses measure 38 inches by 80 inches—5 inches longer than a standard twin. Twin XL beds are common in college dorm rooms and great for taller individuals.
Queen size mattresses are one of the most popular mattress sizes among single adults living on their own—they provide more room to stretch out across and a good choice for smaller master bedrooms. Queen beds are 60 inches by 80 inches.
King size mattresses are the largest standard mattress size available (76 inches by 80 inches)—the equivalent of two twin XL beds placed side by side. King beds are perfect for couples who want more personal space. A split king option is also available for couples looking for a mattress to fulfill their personal sleep preferences.
California King Mattress
California king size mattresses have the same area as a king-size bed, but longer and narrower at 72 inches by 84 inches. Cal king beds are also a great option for couples, particularly those who like to sleep closer together. Split Cal king option is not as standard as a split king, but it is available for couples looking to have a mattress based on their personal preference.
What is the difference between a full and a twin bed?
While both a twin and a full bed are the same length, the full size provides 16 extra inches of width to the mattress. Full size mattresses are larger than twin size beds, a better option for teenagers, college students, and single sleepers.
Is a twin big enough for two?
A twin size mattress is 38 inches by 75 inches—while an excellent option for single adults, a twin bed would be far too small for couples. The compact size wouldn’t leave enough room for two people to sleep comfortably.
Is there a bed bigger than a twin but smaller than a full?
A twin XL mattress might be a nice in-between size. Twin XL mattresses are 38 inches wide (the same as a twin) but provide 5 inches of extra length, excellent for taller individuals.
Is a Twin or Full Size Mattress Right for You?
If torn between choosing a twin or a full size mattress, it helps to look at who needs the bed. Twin or full size beds are great for children moving past the crib stage and for teenagers moving out. Both sizes are great options for single sleepers, no matter if they’re kids, teenagers, college students, or single adults.
