Learn how to pick the right linen cotton fitted sheet size for your mattress, with decision rules and trade-offs for Twin through Cal King.
Quick answer
To choose the right linen cotton fitted sheet size, match your mattress dimensions and depth to the sheet's stated size and pocket depth. For most standard mattresses, the labeled size (Twin, Full, Queen, King, Cal King) works, but deep or pillow-top mattresses require checking pocket depth.
Why size matters for linen cotton fitted sheets
Linen-cotton blends have less stretch than all-cotton jersey or microfiber sheets. That means a precise fit is more important — too small and the sheet won't stay on; too large and it bunches. The blend combines linen's durability and texture with cotton's softness, so getting the size right ensures you feel those benefits instead of fighting a loose or tight sheet.
Mattress depth: the hidden variable
Standard fitted sheets fit mattresses up to about 12 inches deep. If your mattress is thicker — common with pillow-top or hybrid models — you need a deep-pocket sheet. The Linen-Cotton Fitted Sheet and Linen-Cotton Fitted Sheet - Cal King both use a proprietary softening wash and 100% natural fibers, but they do not list a specific pocket depth in the catalog facts. If your mattress is deeper than 14 inches, check the product description for pocket depth before ordering.
Decision rules for choosing your size
- Measure your mattress width and length: Use a tape measure to get the exact width and length of your mattress top. Standard sizes: Twin 38"x75", Full 54"x75", Queen 60"x80", King 76"x80", Cal King 72"x84". If your mattress matches these, the labeled sheet size will fit.
- Check your mattress depth: Measure from the top seam to the bottom edge of your mattress. If it's over 12 inches, look for deep-pocket sheets. The Linen-Cotton Fitted Sheet and Cal King version do not specify a maximum depth in their catalog facts, so contact support or check the product page for depth compatibility. If your mattress is deeper than 14 inches, consider a sheet set designed specifically for extra-deep mattresses.
- Match the sheet to your bed size exactly: Do not size up or down. A Queen sheet on a Full mattress will have excess fabric that wrinkles and slips. A Full sheet on a Queen bed will not cover the corners. Stick to your measured size.
