Bed Mattress Size Chart for US, UK, EU, RV, Trucks

Baby Crib mattress size dimensions are widely accepted to be the standard across the U.S., so that this bed size will fit any standard crib. A crib-size mattress should not be more than 6 inches thick. For safety reasons, crib mattresses are firmer than adult mattresses.

Suitable for babies who have outgrown their crib (cot) or toddlers, the Small Single size mattress is among the smallest mattress available.

A Twin size mattress is the smallest of adult-size mattresses. A Twin size mattress would be suitable for a child who has outgrown the toddler bed, a single adult, or those with small bedrooms. A twin mattress is commonly used for daybeds, bunk beds, dorm rooms, or small guest bedrooms.

Twin XL beds are 38" x 80", giving you an additional 5" in length that the twin size allows you to stretch out your legs and are ideal for the single taller person. Two Twin XL mattresses make up the dimensions of one King size mattress and fit in a King size bed frame allowing sleepers to separately sit up or lie back without disrupting their partner.

A Full-size mattress may also be referred to as a "standard double." Full-size mattresses provide a good compromise between twin and queen-size mattresses for single active sleepers who like to sprawl out or couples with small bedrooms. Two people can sleep comfortably but compactly on a full or double. A full bed size offers a good amount of space for single sleepers and is a good bed size option for a guest bedroom.

The full xL size mattress is 5 inches longer than a standard full mattress. The extra length provides greater legroom making it a great fit for taller single sleepers.

A queen-size mattress is great for couples who do not need too much space for sleeping or for a single adult who prefers extra space to sprawl out. This is a trendy mattress size in the U.S and is a comfortable fit for single active sleepers, couples, and those who share a bed with children or pets.

The Olympic queen size is six inches wider than the popular queen-size mattress. A traditional King or Queen size frame will not fit a traditional King or Queen size frame. You will need an Olympic Queen bed frame that measures 66" wide and 80" long. These are the better option for those who don't need something super large but something big enough for a couple to sleep comfortably. However, as the Olympic queen-size bed isn't standard, few mattress manufacturers have this size and finding compatible bed frames and bedding accessories may be challenging.

Offering a luxurious amount of space, king mattress sizes provide the equivalent of a twin xl mattress size to themselves. King-size mattresses are wider but shorter than California king-size mattresses. The king size also has a split option (see next mattress down). These are two Twin XL mattresses placed side-by-side. This style is also a good fit for adjustable beds with split-side functionality.

A Split King size mattress uses two identical Twin XL-sized mattresses equal to the size of a complete King size mattress. The split mattress allows sleepers to have a mattress that is individually right for them.

A California king is sometimes known as the extra-long king when it comes to California king vs. king beds. California king-size mattresses have four inches less width than a conventional king-size bed and are 4 inches longer in overall length. If your feet hang off the edge of a mattress, a California king-size mattress will provide you with the length you need.

A Wyoming king bed is 8 inches wider and 4 inches longer than a standard king-size bed, which measures 76 inches by 80 inches. It's a good option for families who feel cramped in large-sized beds. If you have to accommodate more sleepers, a Wyoming king may be a better fit than a Texas king-size bed.

The Texas king bed mattress is perfect for individuals who need that extra leg room. Measuring 80 inches by 96 inches, the Texas king bed is narrower than the Wyoming king. However, it compensates for this loss by being 14 inches long.

One notable feature of the Alaskan king is its larger size and unique shape - it's big, square - with dimensions at a whopping nine feet long by nine feet wide, space will always be abundant. An Alaskan King is much bigger than a California King, measuring 24 inches long and 36 inches wider.
