The Ultimate Bed Size Guide
Buying a mattress is one of the most important investments for your health. Choosing the wrong size can lead to cramped sleep for couples or a bedroom that feels impossibly small.
Standard Bed Dimensions (US)
- Twin: 38" x 75" - Ideal for children or small guest rooms.
- Full (Double): 54" x 75" - Great for single adults who want more space.
- Queen: 60" x 80" - The standard for couples.
- King: 76" x 80" - Maximum space for couples and pets.
- California King: 72" x 84" - Best for very tall people (6'2" and above).
Considering Room Clearance
A bed might fit into a room, but can you walk around it? Our calculator checks for at least **24 inches (60cm)** of clearance. This is the minimum required to move naturally without feeling claustrophobic. If you have a nightstand or dresser, you may need even more space.
Tall Sleepers
If you are taller than 6 feet (183cm), standard Twin and Full beds may feel too short. An extra-long (XL) or a Queen/King (which are 80-84 inches long) will provide much-needed legroom.
