How much backing for a crib size quilt?
Crib quilts need 2 3/4 to 3 yd of backing fabric, or 1 3/8 to 1 1/2 yd of 108″ wide backing. The most common crib size, 45″ × 60″, takes 3 yd.
Every crib size
| Quilt | 42″–44″ fabric | Seams | 108″ wide | Metric (110 cm) |
|---|---|---|---|---|
| 40 × 60 | 2 3/4 yd | 2 panels, horizontal seam | 1 3/8 yd | 2.5 m |
| 45 × 60 | 3 yd | 2 panels, horizontal seam | 1 1/2 yd | 2.7 m |
Each size allows 4″ extra on every side for quilting (most long-arm quilters ask for 4″–6″) and about 40″ of usable width from 42″–44″ cotton. Open a size for the step-by-step math and other overhangs.
Which crib size is yours?
Sizes depend on the mattress and how far you want the quilt to hang. See what size quilt for a crib bed for every drop, or the full quilt size chart. Same quilts: how much binding for a crib quilt, batting and all the fabric.
Questions quilters ask
How much backing do I need for a crib size quilt?
2 3/4 to 3 yd of 42-44 inch quilting cotton, depending on the size. A 45 x 60 inch crib quilt needs 3 yd (2 panels, horizontal seam), allowing 4 inches extra on every side for quilting.
How much 108 inch wide backing for a crib quilt?
1 3/8 to 1 1/2 yd. Every common crib size fits on one width of 108 inch backing, so there are no seams.
Which way should the seams run on a crib quilt backing?
For 45 x 60, horizontal seams take 3 yd and vertical seams take 3 7/8 yd. Work out both: the cheaper direction depends on the quilt's width and length.
