How Wide is a Twin Bed?

When venturing into the world of mattresses, especially if you're setting up a room for a child, guest, or for yourself, the twin size often comes into play. But just how wide is a twin bed? And why is this size so popular?

Twin Bed Dimensions

A standard twin bed is 39 inches in width and 75 inches in length. In centimeters, this translates to approximately 99 cm in width and 190.5 cm in length. This makes it an ideal choice for smaller bedrooms or multi-use rooms.

Comparing Twin Bed to Other Sizes

The twin bed's width positions it as the narrowest standard bed size available. When compared to a full or queen bed, it’s notably slimmer. This slim profile is what makes it a go-to choice for rooms with limited space.

Ideal Users for a Twin Bed

Due to its width, the twin bed is perfect for children, teens, and single adults. It’s often the first 'big kid' bed many children transition to after outgrowing their cribs.

The Popularity of the Twin Bed

Twin beds aren't just popular in homes. They're a staple in college dormitories and are frequently used in hostels. Their efficient width allows for optimal use of floor space.

Accessorizing a Twin Bed

When shopping for bed frames, sheets, or any accessories, always consider the bed's width. Standard twin-sized accessories are abundant, making it a cost-effective option.


The twin bed’s width, at a standard 39 inches, makes it a versatile piece of furniture suitable for various settings, from compact city apartments to spacious suburban homes.
