3 7/8 yd
of standard 42″–44″ quilting cotton — 2 panels × 68″ with 1 vertical seam. Or 2 yd of 108″ wide backing (one piece, no seams — cut 68″). Metric: 3.5 m of 110 cm fabric.
How it's worked out
- Add 4″ on every side for quilting (long-arm quilters usually ask for 4″–5″): 60 + 8 = 68″ wide, 60 + 8 = 68″ long.
- Quilting cotton is 42″–44″ wide; after trimming selvages about 40″ is usable, and each seam takes 1″.
- Running the seams vertically you need 2 widths of fabric, each 68″ long.
- 2 × 68″ = 136″ = 3.78 yards → round up to the next ⅛ yard: 3 7/8 yd.

Same quilt: binding & batting
- Binding for a 60 × 60 quilt: 7 strips of 2½″ → 1/2 yd.
- Batting: at least 68″ × 68″ — a Twin package fits, or 2 yd off a 96″ roll.
