Bedding & Bed Size Charts
Plan a bedroom purchase from one place: mattress footprints, sheet sizes, blanket coverage, and side-by-side comparisons before you buy.
What do you need?

Bed size vs mattress size
Shoppers often search for "queen bed size" or "king bed dimensions"—for standard US beds, those numbers are the same as the mattress. Sheets and duvets use slightly larger dimensions for overhang; see our bed sheet chart and blanket chart.
