A throw-size quilt (50×65″) with medium-density quilting needs approximately 200–400 yards of top thread. Dense quilting (stipple/meander) can use 2–3× that amount.
A 1,100-yard spool of 50wt thread covers most throw quilts with medium quilting. Dense quilting on larger quilts may need 2–4 spools. Always buy extra if matching a specific color.
50wt cotton or polyester thread is the standard all-purpose choice. It blends into the quilt top for an invisible quilting look. Use 40wt or 28wt for decorative, visible stitching.
Enormously. Micro quilting at 8 lines per inch uses 8× more thread than sparse stitch-in-ditch at 1 line per inch. Plan your thread budget based on density, not just quilt size.
