Quilt batting size calculator
Start with your finished quilt size. We add room around the edges, then tell you the batting rectangle to look for and whether a common packaged size covers it.

Questions quilters ask
How much bigger should batting be than a quilt top?
This calculator adds 4 inches of overhang on every side, so the batting rectangle is 8 inches wider and 8 inches taller than the finished top.
What if no standard batting package fits?
For a larger quilt, look for batting sold from a wide roll or plan to piece batting according to the manufacturer's directions.
