How Much Fabric Do You Need for a Quilt?
A queen-size quilt needs approximately 7.5–10 yards of 42-inch quilting cotton for the top, plus 8 yards for backing and 0.75 yards for binding. The exact amount depends on quilt size, number of fabrics, and block design.
Total Fabric by Quilt Size
Includes 15% overage for cutting waste. Based on 42-inch quilting cotton.
| Size | Dimensions | Top Fabric | Backing | Binding | Grand Total |
|---|---|---|---|---|---|
| Baby | 36" × 52" | 1.5–2 yd | 1.75 yd | 0.5 yd | ~4 yd |
| Throw | 50" × 65" | 3–4 yd | 3.5 yd | 0.5 yd | ~8 yd |
| Twin | 60" × 80" | 4–5.5 yd | 5 yd | 0.75 yd | ~11 yd |
| Full | 80" × 90" | 6–7.5 yd | 7.5 yd | 0.75 yd | ~15 yd |
| Queen | 90" × 108" | 7.5–10 yd | 8 yd | 0.75 yd | ~19 yd |
| King | 108" × 108" | 10–13 yd | 9.5 yd | 1 yd | ~24 yd |

Three Types of Fabric You Need
1. Quilt top fabric
The quilt top is the decorative side (the patchwork, the design). If you are using 3 fabrics in equal amounts for a queen quilt, divide the top yardage (about 9 yards) by 3, so 3 yards per colour. If one fabric dominates, adjust the split accordingly.
Always add 15% for cutting waste. Patchwork quilting generates more waste than garment sewing because you are cutting many small pieces from larger yardage.
2. Backing fabric
The backing is the bottom layer. It should be at least 4 inches larger than the quilt top on all sides (8 inches total added to width and length). For quilts wider than 42 inches, you need to seam two or three widths of standard quilting cotton, or buy 108-inch wide-back fabric to avoid seams entirely.
3. Binding fabric
Binding wraps the raw edges. The standard method uses 2.5-inch strips cut on the straight grain. You need enough strips to cover the quilt’s perimeter plus 20 inches for corners and joining. Most quilts need 0.5–1 yard of binding fabric.
How to Plan Your Fabric Purchase
1. Choose your quilt size based on the bed it will cover. Add 12–20 inches per side for mattress drop if you want overhang.
2. Decide on your colour count. More colours means less of each fabric. Fewer colours means larger cuts and more visual impact.
3. Calculate per-colour yardage. Run your numbers through the patchwork yardage tool to get exact amounts for each colour, plus backing and binding.
4. Check the quilt yardage chart for a quick sanity check against standard amounts.
5. Buy from one dye lot. Quilting cotton colours vary between dye lots. Buy all your yardage at once.
6. Pre-wash if you plan to wash the finished quilt. Quilting cotton can shrink 3–5%. Our shrinkage guide covers rates by fabric type.
