What are the average dimensions of a youth's bed?

A youth bed is generally 66 inches long and 33 inches wide. Actual retail youth beds can be larger or smaller, varying in size by up to two inches.

A youth bed is larger than a toddler bed and smaller than a twin bed. It is usually bought for children after they have outgrown their toddler beds. Youth beds are cheaper than twin beds. They also usually include side rails that twin bed frames lack. However, twin beds could be used for a longer period because fast-growing children can outgrow their youth beds in a few years, as stated by MattressSizeGuide.com
