What to know
U.S. Consumer Product Safety Commission rules for full-size cribs require the mattress to be at least 27 1/4 × 51 5/8 in and no more than 6 in thick, so most are sold as 28 × 52 in.
Mattress sizes are nominal. Individual brands can be up to about 1 in (2–3 cm) smaller, and the bed frame adds to the footprint: a platform frame usually adds 1–4 in to each side, and a headboard adds 2–6 in to the length.
