Bed size vs mattress size
In the US, bed size and mattress size share the same footprint for standard frames. A king size bed uses a 76 × 80 in (193 × 203 cm) mattress; a queen bed uses 60 × 80 in (152 × 203 cm). Frames may add a little overall width for side rails—check the product listing.
Mattress toppers and protectors: buy the same size label as your mattress (King topper for King mattress). Thickness is separate from length and width.
