Bed size vs mattress size
In the US, bed size and mattress size refer to the same footprint for standard frames. A queen size bed takes a 60" × 80" mattress; a king size bed takes 76" × 80". Bed frames and box springs may add a few inches of overall width for side rails—check the product listing before you buy.
Need fitted sheets or duvet coverage? See our bed sheet size chart and blanket size chart for dimensions beyond the mattress itself.
How to Choose the Right Mattress Size
1. Consider Your Room Size
Measure your bedroom and ensure there's enough space around the bed. A good rule of thumb is to leave at least 2-3 feet of walking space on all sides.
2. Number of Sleepers
For single sleepers, Twin or Full works well. Couples should consider Queen (most popular) or King for more space. California King is ideal for tall couples.
3. Personal Space Preferences
If you prefer more personal space while sleeping, choose a larger size. King offers the most space for couples, equivalent to two Twin XL mattresses side by side.
4. Bed Frame Compatibility
Ensure your mattress size matches your bed frame. Using a smaller mattress on a larger frame (or vice versa) can cause safety issues and discomfort.
