Quilt Layout & Sashing Calculator
Find out how many blocks you need and how big your quilt will be, with or without sashing and cornerstones.
How to Use the Quilt Layout & Sashing Calculator
1. Choose whether you know your number of blocks or the quilt size you want.
2. Enter your finished block size.
3. Enter the blocks across and down, or the size you want.
4. Add a sashing width if you are using sashing.
5. Select Calculate Layout.
Please note: Calculations use a 40" usable width of fabric (WOF) and ¼" seams unless you choose otherwise. Results are a helpful guide; patterns, fabrics and cutting vary, so allow a little extra.
