The Differences Between Twin and Twin XL

The twin XL size is also interchangeably referred to as extra-long twin, TXL, twin extra-long, or extended twin size. Here are some of the differences between the twin size and the twin XL size:

Mattresses

A twin size mattress is 39 inches wide and 75 inches long

A twin XL size mattress is 39 inches wide and 80 inches long

The extra length of the twin XL size mattress makes it more comfortable for adults, the tall ones in particular. This is one of the reasons why twin XL size mattresses are used by most colleges. Because of the extra length of the twin XL size, it needs bedding (fitted bottom sheets and mattress pads in particular) with sufficient length to accommodate its larger size. Although some manufacturers produce the same dimension for twin and twin XL blankets, flat sheets, and comforters, the dimension still varies for some manufacturers. However, the average dimensions are:

A twin size mattress pad is 39 inches wide and 75 inches long

A twin XL size mattress pad is 39 inches wide and 80 inches long

This is the top dimensions of the fitted sheet or mattress pad after it has been stretched on the mattress. Therefore, you must know the depth of your mattress or thickness and choose a fitted sheet or pad with the right pocket depth to get a fitted sheet or mattress pad that fits well.

For a standard-depth mattress (7 inches to 9 inches thickness), you will need a standard pocket depth of around 7 inches and 14 1/2 inches.

For a deep mattress (10 inches to 15 inches thickness), you will need a pocket depth of around 10 inches and 15 inches.

For an extra-deep mattress (16 inches to 22 inches thickness), you will need a pocket depth of around 16 inches and 22 inches.

Blankets, Comforters, and Flat Sheets

On average, twin size blankets are 66 inches wide and 90 inches long. The twin size blanket shares the same size with the twin XL blanket.

Normal twin size comforters should be 68 inches wide and 88 inches long. While twin XL size comforters are 68 inches wide and 90 inches long. Sometimes, twin XL size comforters are longer than 90 inches.

A typical twin flat sheet is 66 inches wide and 96 inches long. And while some manufacturers produce the same size for twin XL size flat sheets, other manufacturers produce longer sheets of up to 102 inches long.
