When you buy a mattress it's important to consider the perfect size for you or whoever you're buying for. So whether you're taller, a single sleeper, or want to know the best size for a little one, we've covered the standard sizes below and given some recommendations.

Twin
Great for single sleepers, kids/teens
Dimensions: 38in x 75in, or 3’x 6’3”
Perfect for kids, teens and single sleeping adults. Ideal size for bunk beds and smaller rooms

Twin XL
Great for single sleepers, kids/teens
Dimensions: 38in x 80in, or 4’x 6’3”
Ideal for taller members of the family and rooms that need more space. Put two twin XLs together for single sleepers to stretch out. Visitors will love a Twin XL in the guest room!

Full
Great for couples
Dimensions: 54in x 75in, or 4'6" and 6'3"
Perfectly suits couples and medium/small rooms, often the best size for standard bedrooms and generally spacious enough for two sleepers comfortably or for single sleepers to stretch out

Queen
Great for couples and taller people
Dimensions: 60in x 80in, or 5'0" and 6'8"
a larger size can suit couples that like a bit more space than a full. Also ideal for taller people

King
Great for couples and taller people
Dimensions: 76in x 80in, or 6'3" and 6'6"
A great option for couples who enjoy more space and for those that are tall and prefer the additional mattress length. Considerably wider than a full, a king needs additional room

California King
Great for couples and taller people
Dimensions: 72in x 84in, 6'0" and 7'0"
You and your partner want oodles more room? California King is perfect for you!
