difference between xl twin and twin
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: 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.
While twin XL is preferable (minimum length of 90), twin comforters and duvets (86 and up) can work on an 80 inch extra long twin mattress but they will be short. Please note that your mattress topper, fitted sheet, mattress pad, and bed skirt must be manufactured to properly fit a twin extra long mattress.
