Twin bed frames, sized 38 by 75 inches
A twin mattress measures 38 by 75 inches, the smallest of the five standard sizes. It is the usual choice for a child moving out of a toddler bed, a bunk or loft setup, a small guest room, or a studio where floor space decides everything.
Trundle, storage and platform
Trundle frames hold a second twin mattress underneath on castors, so one footprint sleeps two. Storage frames use drawers built into the base, which replaces a dresser in a small room. Platform frames sit on slats and need no box spring.
Fitting a twin into a small room
A twin frame usually occupies about 40 by 78 inches once rails and headboard are counted. Against a wall it leaves walking space on one side only, so measure the door swing and check that a trundle has clearance to roll out before ordering one.
