Questions quilters ask
What size batting do I need for my quilt?
The same size as the backing: the quilt top plus 4 inches on every side. A 90 x 108 inch queen quilt needs batting at least 98 x 116 inches, so a King (120 × 120) package.
What size is queen batting?
Queen batting packages are usually 90 x 108 inches and king packages 120 x 120 inches, but sizes vary by brand, so check the label. A queen package is too small for a 90 x 108 inch quilt once the 4 inch overhang is added.
Can I buy batting by the yard?
Yes. Batting on a roll is commonly 90, 96, 108 or 120 inches wide. The calculator above shows how much to buy off a 96 or 120 inch roll for your quilt.
