The twin is the one that does not match the usual mattress width. If you want standard twin sheets to fit, measure the inflated bed or pick a listing that matches 38 × 75 in. For regular mattress dimensions, see the mattress size chart and sheet sizes. For a guest bed that tucks away without inflating, see trundle and daybed sizes.
