How to Choose the Right Mattress Size
Room Size & Layout
Measure your space and leave at least 24″ of clearance on each side of the bed. Here’s a quick guide:
- Twin: Fits rooms as small as 7′ x 10′
- Full: Best in rooms 9′ x 10′ or larger
- Queen: Ideal for rooms around 10′ x 10′
- King/California King: Require at least 12′ x 12′
Number of Sleepers
A Queen suits most couples, but if you move a lot or sleep with pets, go larger. See our best mattresses for couples guide for more insight. Also check Better Sleep Council for expert sleep advice.
Your Sleep Style
- Side sleepers: Need more space to shift
- Back/stomach sleepers: Need firmness and support
- Combination sleepers: Benefit from larger sizes for freedom to move
Budget & Accessories
Larger beds cost more and need bigger frames and bedding. For value, Queen size often hits the sweet spot. Compare costs in our Mattress Buying Guide and on Consumer Reports.
Height & Body Type
Taller individuals (6’+) should avoid Full or Queen. Try Twin XL or Cal King instead for legroom. Larger sleepers will appreciate the extra width of King sizes for better rest.
Bedding Compatibility
Queen and King sizes offer the most options. If you’re investing in quality linens, standard sizes simplify shopping. Our Bedding Sets Guide explores the best combos.
Choosing from the wide range of mattress sizes doesn’t need to be overwhelming. Focus on your space, sleep style, and lifestyle needs. A well-matched mattress size leads to better sleep and a more functional bedroom.
