What each calculator works out
- Backing: how much fabric to buy and how to seam the panels.
- Binding: how many strips to cut and the fabric they take.
- Borders: strip lengths and fabric for butted borders.
- Batting: the size you need and the smallest listed package that fits. Pick Batting in the switch above.
- Fabric for Pieces: yardage for a count of squares or rectangles.
Allowances we start with, and what to change
Backing and batting start with 4 inches on each side. Choose Longarm for 6 inches, or type what your quilter asks for. Regular fabric starts with a usable width of 40 inches, which leaves out the selvages. Every one of these values sits in its own field, so you can change it.
How to read the result
The big line is what to buy. Yards and meters are always shown together. Each is rounded up to the next step you can buy, straight from the full length, so meters are not converted from rounded yards. Open "How this was calculated" to follow the numbers.
Questions
Do I need an account?
No. The calculators work in your browser without signup.
Can I use centimeters?
Yes. Switch to Centimeters and meters; results show yards and meters together.
How much extra should I allow?
We start with 4 inches per side for backing and batting. Ask your longarm quilter and change the value.
