Fabric may be rotated to use less yardage.

Backing cuts include 4" extra on each side; each backing seam uses 1" of panel coverage. Estimates are for planning only. Check your pattern, fabric width, shrinkage, quilting method, and longarm requirements.

Backing Direction Changes Yardage
Two ways to piece a backing can use different amounts of fabric.
The calculator compares both directions, then recommends the one that uses fewer yards. If yardage ties, it favors fewer seams.
Quilt Backing Size Chart
Finished sizes, suggested backing cuts, and base fabric estimates. Backing cuts include 4" extra on each side. Base estimates assume non-directional fabric and use the lower-yardage cutting orientation.
| Quilt Type | Common Finished Size | Suggested Backing Cut Size | Regular Cotton Base (42") | Wide Backing Base (104") |
|---|---|---|---|---|
| Baby gift quilt | 36" x 45" | 44" x 53" | About 2 1/2 yards | About 1 1/4 yards |
| Lap quilt | 45" x 55" | 53" x 63" | About 3 yards | About 1 1/2 yards |
| Throw quilt | 50" x 60" | 58" x 68" | About 3 1/4 yards | About 1 3/4 yards |
| Large throw quilt | 60" x 72" | 68" x 80" | About 4 yards | About 2 yards |
| Twin quilt | 64" x 86" | 72" x 94" | About 5 1/4 yards | About 2 yards |
| Full quilt | 80" x 90" | 88" x 98" | About 7 1/2 yards | About 2 1/2 yards |
| Queen quilt | 90" x 100" | 98" x 108" | About 8 1/4 yards | About 3 yards |
| King quilt | 108" x 108" | 116" x 116" | About 9 3/4 yards | About 6 1/2 yards |
How this estimate works
- Backing cut size adds 4" to each side of the finished quilt.
- Backing width = finished quilt width + 8".
- Backing length = finished quilt length + 8".
- Each backing seam uses 1" of panel coverage.
- Yardage is a base planning estimate rounded up to the nearest 0.25 yard.
- Check pattern instructions, actual fabric width, quilting method, shrinkage, and longarm requirements before buying.
View assumptions
- Regular quilting cotton is usually 42–44" before trimming selvages; this calculator plans with about 42" usable and may require piecing.
- Wide backing fabric is often about 108" before trimming; this calculator plans with about 104" usable and can reduce seams on larger quilts.
- Optional 5–10% extra shopping buffer is separate unless stated
FAQ
For beginner planning, many quilters add about 4" extra on each side. If you use a longarm quilter, ask for their specific backing requirements.
Using 4" extra on each side, a 50" x 60" throw quilt needs a backing cut size around 58" x 68".
Yes, but larger quilts may need pieced backing because regular quilting cotton is usually not wide enough for the whole backing in one piece.
No. This chart gives beginner planning estimates. Always check your pattern and fabric width before cutting.
