King Quilt Size Guide

King quilts are large projects that require careful fabric planning. Wide backing fabric is especially popular for this size.

Standard King Quilt Size

The standard king quilt size is 108 inches by 108 inches for a square king quilt. Some quilters make a 100" × 112" rectangular version for a California king mattress.

Wide Backing Fabric

108-inch wide backing fabric is ideal for king quilts. A 108" × 108" king quilt typically needs about 3.5 yards of wide backing, saving you from piecing multiple panels.

Binding and Batting

Binding for a king quilt requires about 460 inches of total length, or roughly 12 WOF strips. Use king-size batting or a large cut measuring about 116" × 116".
