Nominal listings vary between 53 × 80 and 54 × 80 in. This record uses 54 × 80 in and flags the one-inch width variation.
Current width listings differ
Brooklyn Bedding lists 53 × 80 in while Mattress Insider lists 54 × 80 in. That difference is why this page treats Full XL as a specialty market convention rather than one regulated standard.
Build the support set before buying
Full XL frames, foundations, and fitted sheets are less common than standard Full or Queen components. Verify each finished dimension and support requirement together.

Bedding fit
Use the mattress measurements, not only “Full XL.”
Applicable market labels include Full XL. These labels do not guarantee a particular finished sheet, duvet, comforter, blanket, or bedspread dimension.
For a fitted sheet, also measure mattress depth, topper, pad, and extra pocket allowance. For top bedding, choose the side and foot coverage you want.
