Batting Calculator 🧶

Calculate the exact batting size needed for your quilt. Enter quilt dimensions, overhang, and batting roll width to get required batting size, cut length, and seaming requirements.

How to Use the Batting Calculator

Enter your quilt's finished width and height, then set the overhang — the extra batting that extends beyond each edge of the quilt (typically 2–4" per side). This overhang is essential for loading the quilt into a frame and for the quilting process.

Select the batting roll width available to you (90", 96", or 120"). If your required batting width exceeds the roll width, the calculator will tell you how many panels to cut and join. Batting seams should be butted (not overlapped) and hand-stitched together.

Choose your batting type to see its characteristics. Cotton is flat and breathable; polyester is lightweight with high loft; wool is warm and moisture-wicking; bamboo is eco-friendly and soft; blends offer a balance of properties. Always pre-shrink cotton batting by soaking in warm water before use.
