How Much Fabric for a Crib Quilt Backing?
For a 36 x 52 inch crib quilt with 4 inches extra per side, buy 2 1/2 yards of 42 inch quilting cotton (2 panels, horizontal seams) or 1 1/4 yards of 108 inch wide backing. If your longarmer asks for 6 inches per side, plan 2 3/4 or 1 3/8 yards.
This page works out backing for a crib quilt top of 36 x 52 inches, the typical size in our quilt size chart. If your top is a different size, the quilt backing calculator runs the same math for any measurement.
How much crib backing do you need for each overage?
Overage is the extra backing added to every side. Home quilters often use 2 to 4 inches, while longarm quilters typically want 4 to 6 inches so the frame can clamp the fabric.
| Extra per side | Backing size (in) | 42 in, vertical | 42 in, horizontal | 108 in wide |
|---|---|---|---|---|
| 2 in | 40 x 56 | 1 5/8 yd (1) | 2 1/4 yd (2) | 1 1/8 yd |
| 4 in | 44 x 60 | 3 3/8 yd (2) | 2 1/2 yd (2) | 1 1/4 yd |
| 6 in | 48 x 64 | 3 5/8 yd (2) | 2 3/4 yd (2) | 1 3/8 yd |
| 8 in | 52 x 68 | 3 7/8 yd (2) | 3 yd (2) | 1 1/2 yd |
How do you piece a backing for a crib quilt?
With 4 inches per side, the cheapest layout for standard cotton is horizontal seams. Here is the cutting plan.
- Buy 2 1/2 yards of 42 to 45 inch quilting cotton, in one continuous length if possible.
- Cut 2 panels, each 44 inches long.
- Trim the selvages from both long edges of every panel.
- Sew the panels together along the long edges with a 1/2 inch seam and press the seams open. The finished piece needs to be at least 60 inches across, so the last panel only needs to be about 20 inches wide and you can trim the extra.
- Square the backing to about 44 x 60 inches and mark the center of each edge.
Seams and longarms
Many longarm quilters prefer backing seams that run horizontally, parallel to the frame rollers, because the fabric rolls more evenly. If yardage is close, ask which way your quilter wants the seams.
Does fabric width change the crib backing yardage?
Quilting cotton is sold as 42 to 45 inches wide, but the usable width after trimming selvages, and after prewashing, can be 38 to 44 inches. For some sizes that difference adds a whole panel.
| Usable width | Best layout | Yards |
|---|---|---|
| 38 in | 2 panels, horizontal seams | 2 1/2 yd |
| 40 in | 2 panels, horizontal seams | 2 1/2 yd |
| 42 in | 2 panels, horizontal seams | 2 1/2 yd |
| 44 in | 1 panels, vertical seams | 1 3/4 yd |
What if your crib quilt is bedspread size?
A bedspread-style crib quilt that reaches toward the floor (a 22 inch drop plus a 12 inch pillow tuck) finishes near 72 x 86 inches. Its backing needs 5 1/4 yards of 42 inch cotton (2 panels) or 2 1/4 yards of 108 inch wide backing.

Is it cheaper to send a crib quilt to a longarmer or quilt it yourself?
Longarm services usually price by the square inch of the top. A crib top is 1,872 square inches, so even a modest edge-to-edge rate adds up across several quilts a year. Run your own numbers in the longarm cost calculator before deciding whether a sit-down longarm or frame belongs in your sewing room.
Frequently asked questions
How many yards of fabric do I need for a crib quilt back?
A crib quilt of 36 x 52 inches needs a 44 x 60 inch backing with 4 inches extra per side. In standard 42 inch cotton with about 40 inches usable, that is 2 1/2 yards cut into 2 panels. In 108 inch wide backing it is 1 1/4 yards. Buy an extra 1/4 yard if you plan to prewash or match a large print.
Should I use wide backing for a crib quilt?
It is optional. A crib back pieces from 2 panels of 42 inch cotton with 1 seam, so standard fabric works well and lets you match the quilt top. Wide backing (1 1/4 yards) only saves the seam and the pressing time.
How much extra backing does a longarm quilter need for a crib quilt?
Most longarm services ask for 4 to 6 inches extra on every side, and a few ask for 8. At 6 inches per side, the crib backing grows to 48 x 64 inches, which is 2 3/4 yards of 42 inch cotton or 1 3/8 yards of wide backing. Ask before you cut, because a short backing is the most common reason a quilt is sent back.
How do I cut and sew a pieced crib quilt backing?
Cut 2 panels of 42 inch cotton, each 44 inches long. Trim off the selvages, since they shrink differently. Sew the panels along their long edges with a 1/2 inch seam, press the seams open, then trim the pieced back to about 44 x 60 inches. Mark the center of each side to help line it up with the top.
Does washing fabric change how much backing I need?
Yes. Prewashed quilting cotton can lose 1 to 2 inches of width and several inches of length per yard, and trimmed selvages take another inch. If you prewash, plan with 38 to 40 inches of usable width. The usable width table on this page shows how the yardage changes, and a small change can add a whole panel on bigger quilts.
