Bed Size Chart: Frame Dimensions & Room Sizes
Last updated:
Quick answer
A bed frame is usually 3-6 in wider and longer than its mattress, so a Queen frame is about 64 x 84 in. Plan for a minimum room of about 10 x 10 ft for a Queen and 12 x 12 ft for a King.

Tips
- Leave 24-30 in of clear space on each walkable side.
- Check door and stair widths before delivery.
- Match sheets to the mattress depth, not just size.
