Why Mattress Size Matters
The size of your mattress affects how comfortably you sleep. It also impacts how spacious your bedroom feels. A mattress that’s too small can make sleep uncomfortable, while one that’s too big can take up too much space.
Before we compare twin, full, queen, and king mattresses, let’s talk about how to pick the right size based on who will be sleeping in it and how much space you have. With a few key features of each size, you can easily choose the right one for you.

What differs the sizes of mattress
Your mattress size depends on how many people will sleep on it, how much room you have, and your personal preference.
Â
Who Gets to Sleep on the Mattress
Â
- Single Sleepers: A twin or full mattress is best for solo sleepers. A twin works for shorter people or kids, while a full gives more space to move around.
Â
- Couples: Couples should choose a queen or king mattress. A queen (in Canada) is a great option, while a king gives both people enough space to sleep without disturbing each other.
Â
Room Size
The size of your room affects your mattress choice. King and queen mattresses are best for large rooms, while twin and full mattresses work well in smaller rooms.
Â
- Miniature Rooms: Twin or full mattresses are great for small bedrooms or guest rooms.
- Middle-sized Bedrooms: Queen mattresses fit most average-sized rooms.
- King: A king mattress is perfect for spacious rooms.
Â
Sleeping Habits
Katie in Kansas City: Where and how you sleep also matter when picking a mattress. If you toss and turn at night, you’ll be more comfortable with a larger mattress like a queen or king. If you sleep still, a twin or full might be enough.

Consider Other Sizes
If you need a mattress for a unique space, like an Airstream, consider non-standard sizes. While Twin, Full, Queen, and King are the most common, other sizes are available to fit your needs.
Twin XL
The Twin XL expands the twin size but with added length. A 38″ by 80″ is ideal for the taller of us or for college dormitories.

Full XL
A Full XL mattress measures 54 inches by 80 inches, which is longer than the standard Full. Queen and King are more prominent still, of course; maybe a bit much for a taller person who may not have enough space in the room for either.

California King
72 x 84 a California King is slightly narrower and longer than a standard King, which would work best for taller sleepers.
