Square quilt block & fabric calculator
Plan a simple quilt made from equal square patches.
How it works
This tool covers equal plain squares only, not triangles, strip-pieced blocks, borders, backing or binding. Cut square = finished square + two seam allowances. It groups squares into whole rows across the fabric width.
A worked example
An 8 × 10 layout of finished 6-inch squares gives a 48 × 60-inch quilt top. With quarter-inch seams, cut each square at 6.5 inches.
