A free quilt calculator for your website
For quilt shops, longarm quilters and guilds. Customers keep asking how much backing to bring or how much binding to cut. Put the answer on your own site: a backing, binding or batting calculator that starts with your extra-per-side rule and shows your name.
- Free, no sign-up, no ads, no cookies.
- Your numbers: 4″, 5″ or 6″ extra on each side for longarm backing, your binding strip width.
- Inches & yards or centimetres & metres; fractions like 60 1/2 work.
- Rounds fabric up to the next ⅛ yard (or 10 cm), so nobody comes home short. How we calculate.

Questions quilters ask
Is the calculator really free?
Yes. No sign-up, no fee, no ads inside the calculator. Quiltwell makes a quilting calculator app; the free calculators are how quilters find us, and the small credit line under the calculator is all we ask.
Will it collect my customers’ data?
No. It sets no cookies and stores nothing about the person using it. We count anonymous page views with Cloudflare Web Analytics, which does not use cookies or fingerprinting.
Where can I paste the code?
Anywhere your website accepts embed code: look for an “Embed”, “Custom HTML” or “Code” block in Shopify, WordPress, Wix, Squarespace and most other site builders. Some builders only allow embed code on certain plans.
My longarm rule is 6 inches per side, not 4. Can it use that?
Yes. Type your number in “Extra on each side” above and the calculator starts with it. If you add your business name, the calculator says that you ask for that much extra, so customers bring the right size backing.
Can I change the numbers later?
Yes. The settings are in the web address inside the code (for example extra=6). Build a new snippet here and replace the old one, or edit the number directly.
