Answer

What size batting do I need?

Packaged batting comes in six common sizes, from 45 × 60 in (crib) to 120 × 120 in (king) (Missouri Star). Pick one at least 2 in bigger than the quilt top on every side; longarm quilters often ask for 4 in.

More questions

What size batting for a queen quilt?

A standard 90 × 95 in queen quilt is wider than queen batting allows with room to spare, so most quilters buy king (120 × 120 in) or batting by the yard.

Can I join two pieces of batting?

Yes: butt the edges together and join them with a wide zigzag or a whipstitch, without overlapping.
