Those who have large spaces and want room to sprawl may prefer a queen or California king. Meanwhile, sleepers with smaller bedrooms or tighter budgets may prefer the cozy price of a twin or full. When looking into smaller options, you may wonder what the difference is between twin XL vs. full beds.

Twin XL vs. Full Dimensions

Twin XL measures 98cm by 200cm while full mattress measures 135cm by 190 cm in Australia. Because twin mattress are longer they are best ideal for tall sleepers with limited space. Full mattresses are either best for shared beds or when one needs little more space to sprawl and stretch.

And because a twin mattress uses less material, they’re normally less pricey compared to full mattress.

Sometimes twin mattresses can be put together to make a bed that’s almost the exact size of a king. These zipped single mattresses can be a great solution for couples prefer different support and feel but still prefer the same bed.

Your height: Due to the difference in length between a twin XL and full mattress, your height also factors into the decision.
