Quilt Batting Calculator
Enter your quilt size. You get the batting size and the packaged size to buy.
How the quilt batting calculator works
Like backing, batting needs to be bigger than the quilt top. Add 3" to 4" on every side, or whatever your longarm quilter asks for.
The calculator compares that size with standard packaged batting (crib 45" × 60", twin 72" × 90", full 81" × 96", queen 90" × 108", king 120" × 120") and with batting sold by the yard in 90", 96" and 120" widths. Exact package sizes vary by brand, so check the label.
Questions
What size batting for a throw quilt?
A 50" × 65" throw needs 58" × 73" batting with 4" extra on each side. A twin package (72" × 90") fits.
Can I piece batting together?
Yes. Butt the edges together without overlapping and join them with a wide zigzag stitch or fusible batting tape.
How much extra batting do longarm quilters want?
Usually 4" on every side, sometimes 6". Ask before you buy.
