According to my research a single measures 36" x 75" and a common "twin" measures 39" x 75". Thus if you laid a twin mattress on a single bed it would surpass the edges on the side by 1.5" on both sides. --Jo Ann
A single bed is just one single A twin bed is two singles in one room - so a twin room
Twin is bunk bed or small single. XL is also called a super single.
Nothing, they are one in the same!
A twin bedroom has two single beds, a double bedroom has a double bed!
Twin X long bed is 5" longer.
A twin bed is actually big enough for only one person--about 36" wide--and is sometimes called a single bed. The twin designation may be because there were often two in a bedroom. A double bed is big enough for two, about 54" wide, as I recall.
A twin bed is 39 × 75 in while a twin extra long is 39 × 80 in. So the extra long is 5 inches longer.
There are a couple of differences between toddler beds and twin beds. First, a twin bed is longer than a toddler bed. Usually, a toddler bed is lower to the ground than a twin bed as well, since it is designed for a child. The most important difference is that a toddler bed usually has bed rails or some other type of enclosure, to insure the child does not roll off the bed. A standard twin bed does not.
A twin bed is smaller and made to fit one person. A full bed is made to fit two people, and it's bigger.
A regular single-sized bed (also referred to as a twin) is typically 39 x 75 inches. A super single is 48 x 84 inches. Note: These are dimensions of the mattresses themselves. The corresponding bed frames will be a little larger to accomodate and support the mattress.
