Before you buy any standard size mattress in a box, there are a few things to consider, such as bedroom size and budget. Below, we outline the dimensions for six standard mattress sizes to help you determine which size suits you or your family’s needs. The general recommendation is that your bedroom offers 24-27 inches of walking space on both sides and at the foot of the bed.
38" x 74"
Twin size mattresses are the smallest on the market, being well suited for kids, bunk beds or extra sleeping space in guest rooms.
Twin XL Size
38" x 80"
Twin XL beds provide five inches of additional length for single sleepers who need that extra room. Twin XL mattresses are great for single sleepers who are taller or for college dorm room beds.
53" x 75"
Full size mattresses are great for a child’s first standard size bed - not too big, but still big enough for snuggles with mom or dad - or for your teenage child. The additional width of a full size makes it suitable for guest rooms, as well.
60" x 80"
Queen size beds are six inches wider than full size, providing just enough breathing room between you and your partner. Queen size mattresses are the perfect size for couples or adults who simply like the extra space.
76" x 80"
King size mattresses are 16” wider than queen size beds, allowing enough room to
not only share the bed comfortably with your partner, but also with your toddler
and maybe even
California King Size
72" x 84"
A california king mattress in a box is not quite as wide as a standard king bed, but measures at 84” long - the longest mattress on the market. California kings are ideal for taller adults, but can also benefit families who like to share the bed.
