Fit checklist
1
Measure width and length
Match the mattress size first: Twin, Twin XL, Full, Queen, King, or California King.
2
Measure height
Include toppers and pads. If the total height is more than 16”, use an extra-deep fitted sheet.
3
Check corners after one night
If the fitted sheet pulls up, wrinkles heavily at the corners, or strains the elastic, move to a deeper pocket.
