How to Choose the Right Size
Sleeping Alone
For single sleepers, Twin, Twin XL, or Full sizes work well. Consider your height and how much space you prefer.
Couples
Queen is the most popular for couples. King offers more personal space. Consider California King if you're both tall.
Room Size
Measure your room and ensure there's at least 2-3 feet of walking space around the bed for comfort and safety.
Children & Teens
Twin or Twin XL work well for children. Consider Full for teenagers who need more space or share rooms.
Tall Sleepers
Twin XL, Queen, and California King offer extra length. California King is the longest standard size available.
Guest Rooms
Full or Queen sizes are ideal for guest rooms as they accommodate most sleepers comfortably.
Bed Frame & Foundation Considerations
When selecting a mattress size, remember that your bed frame and foundation will add to the overall dimensions:
- Bed frames typically add 2-5 inches to each side of the mattress
- Headboards and footboards can add significant length
- Adjustable bases may have different dimension requirements
- Always check that your chosen mattress size is compatible with your bed frame
Important Note
Mattress sizes are standardized, but there can be slight variations between manufacturers. Always confirm exact dimensions before purchasing.
