How it is calculated

Batting, like backing, should extend past the quilt top on every side. Add 4" per side for longarm quilting, 2" for quilting at home.

Packaged batting comes in standard sizes. The calculator picks the smallest package that covers your quilt in either direction.

Questions

Can I join batting pieces?

Yes. Butt the straight edges together and join them with a wide zigzag stitch or fusible batting tape. Do not overlap them.
