A twin mattress, with 38” x 75” dimensions, is the size bed most kids sleep on through childhood. While growth spurts later in adolescence may necessitate upgrades, a twin mattress provides adequate sleeping space for solo sleepers from toddlerhood through the teen years, though most adults find a twin too small.
