Twin Quilt Size Guide
A twin quilt is a practical size for a child's bed, a guest room, or a college dorm. It is the smallest of the standard bed quilts but still large enough to need careful backing and batting planning.
Standard Twin Quilt Size
A common twin quilt size is 70 inches by 90 inches. This covers a standard 38" × 75" twin mattress with a generous drop on the sides and foot.
Backing and Batting
With 108-inch wide backing, a twin quilt typically needs about 2.75 yards in a single piece. With 44-inch fabric you will piece panels and need roughly 5.5 yards. Batting should measure about 78" × 98" to allow overage.
Binding
A 70" × 90" twin quilt has a perimeter of 320 inches plus joining allowance, so you need about 340 inches of binding, or roughly 9 WOF strips at 2.5 inches wide.
