Mattress Sizes & Dimensions Buying Guide
Standard US mattress dimensions (width × length) are:
- Twin: 38 × 75 in
- Twin XL: 38 × 80 in
- Full (double): 54 × 75 in
- Queen: 60 × 80 in
- King: 76 × 80 in
- California king: 72 × 84 in
Actual sizes can vary slightly between brands. Two twin XLs side by side make a king surface, which suits split-firmness and adjustable bases.
When choosing a size, leave walking space around the bed (around 24 to 30 in is a common guideline), measure stairways and doorways for delivery, and remember that mattress thickness affects sheet fit: deep-pocket sheets suit thicker mattresses. Taller sleepers often prefer a twin XL or California king for the extra length. Specialty sizes such as RV short queen and Olympic queen are covered in RV and specialty mattresses.
