Sewing & Quilting Calculators

Every sewing and quilting calculator on the site, covering fabric yardage, seam allowances, quilt block math, and bag or home decor sizing.

Sewing and quilting both depend on precise cutting math — a small measurement error in one seam allowance or one quilt block compounds across a whole garment or quilt top. This category collects every sewing and quilting calculator on the site, from basic fabric yardage to quilt block construction and bag or home decor sizing.

New to quilting specifically? See the quilting basics guide for the three-layer quilt structure, batting choices, and binding fundamentals.

Quilting-specific tools (block sizing, batting, binding) are grouped alongside general sewing and garment tools here, since many quilters use both kinds of calculators across a single project — garment techniques for finishing details, and quilting-specific math for the piecing and layering itself.
