How to Measure Your Mattress
Follow these steps to get accurate measurements:
- Length: Measure from head to foot of the mattress
- Width: Measure from side to side of the mattress
- Thickness: Measure the depth of the mattress for fitted sheet pocket depth
- Add extra inches: For fitted sheets, add 8-15 inches to thickness for proper tucking
Sheet Size Guide
Fitted Sheet Sizing
Fitted sheets should match your exact mattress dimensions plus pocket depth for thickness. Standard pocket depths range from 10-18 inches.
Flat Sheet Sizing
Flat sheets are typically 15-20 inches wider and longer than the mattress to allow for proper tucking and coverage.
Pillowcase Sizing
Standard pillowcases fit pillows measuring 20″ × 26″, Queen pillowcases fit 20″ × 30″, and King pillowcases fit 20″ × 36″.

FAQs about Bed Sheet Size Calculator
What if my mattress measurements don’t match standard sizes?
Use our custom choice in the calculator. Many mattresses vary slightly from standard dimensions. The calculator will recommend the best sheet size for your specific measurements.
How much bigger should my flat sheet be than my mattress?
Flat sheets should be 15-20 inches wider and longer than your mattress. This allows proper tucking and comfortable coverage while sleeping.
Do I need to measure my box spring too?
No, only measure the mattress itself. Box springs don’t affect sheet sizing. Focus on the mattress thickness, length, and width only.
