Twin XL Size

One of the most frequent mattress sizes is Twin XL which is a half of a king mattress. Because of its larger size (38 x 79 ½” or 96.5 x 202 cm), many well-known brands such as Tempur-Pedic also call it as Long Twin. Twin XL may be a better choice for those couples who sleep in adjustable bed as they may regulate own side of the bed independently of each another.
