Questions quilters ask
How much wider should quilt backing be than the quilt top?
This calculator adds 4 inches of overhang to every side. That makes the backing 8 inches wider and 8 inches taller than the finished quilt top.
Will I need to piece my quilt backing?
If the required backing is wider than one usable width of quilting cotton, the calculator shows how many panels are needed and chooses the direction with fewer panels first.
