3 yd
of standard 42″–44″ quilting cotton — 2 panels × 53″ with 1 horizontal seam. Or 1 1/2 yd of 108″ wide backing (one piece, no seams — cut 53″). Metric: 2.7 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″): 45 + 8 = 53″ 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 horizontally you need 2 widths of fabric, each 53″ long.
- 2 × 53″ = 106″ = 2.94 yards → round up to the next ⅛ yard: 3 yd.
Sewing the seams the other way (vertical) would take 2 panels × 68″ with 1 vertical seam = 3 7/8 yd , so horizontal seams save fabric.

| 4″ | 53″ × 68″ | 3 yd (2 panels) | 1 1/2 yd | 2.7 m |
| 5″ | 55″ × 70″ | 3 1/8 yd (2 panels) | 1 5/8 yd | 2.8 m |
| 6″ | 57″ × 72″ | 3 1/4 yd (2 panels) | 1 5/8 yd | 2.9 m |
Same quilt: binding & batting
- Binding for a 45 × 60 quilt: 6 strips of 2½″ → 1/2 yd.
- Batting: at least 53″ × 68″ — a Twin package fits, or 1 1/2 yd off a 96″ roll.
