Project plans include dimensions for a twin-, full-, queen- or king-size mattress (there's no need for box springs with this platform bed). Size your bed from one of two plan options. Queen- and king-size beds require a center divider in the end case and longer side cases to support the larger mattress.
Crib mattress dimensions: 27.25 inches by 51.25 inches. Minimum recommended room size: 7 by 10 feet. Since safety is a top priority for cribs, the size of cribs and mattresses is regulated by the federal government. A full size crib mattress must be at least 27 1/4 inches wide and 51 1/4 inches long.
The standard height varies between 14 to 58 inches, depending on the size of the bed. For example, a twin size headboard dimensions can be 41 inches wide and 14 inches tall, while a king size headboard dimensions can be 80 inches wide and 58 inches tall. A headboard can be 2 to 10 inches thick, depending on its design.
