Backing Yardage Requirements!!
for quilts under 72" wide

(based on 45" wide fabric)

Note: Take the LENGTH of your quilt and double it + 18 inches .

*IMPORTANT*: If the quilt WIDTH is over 72" WIDE you must use the Backing for Large Quilts Chart at the bottom of this page.

These charts provide yardage requirements with seams running down the LENGTH of the quilt from top to bottom. This is ideal for those having their quilts long arm machine quilted as it is best to have the seams laying down the length of the roller bar, instead of wrapping around and around it which can cause bad backing tension issues.

You need to begin with sufficient yardage for the backing.

Take the length of your quilt and double it, adding a half yard to your total. The extra half yard is allowance for shrinkage and uneven cutting.

Thus, if you have a quilt top that is 70 inches per side, you need at least 140 (+18) inches for the back. Ideally you want this in one length, or two 79" lengths.

Large Quilt Backing Yardage Requirements!!
for quilts over 72" wide
(based on 45" wide fabric)

Note: Take the LENGTH of your quilt and triple it + 27 inches (if your tripled LENGTH is more than 154", divide it by 2 then use the chart to find out what half your yardage is and double the yardage.)
Note: If the quilt WIDTH is less than 72" WIDE you must use the (regular) Backing Requirements Chart at the top of this page.

You need to begin with sufficient yardage for the backing.
Take the length of your quilt and triple it, adding 3/4 of a yard to your total. The extra 3/4 of a yard is allowance for shrinkage and uneven cutting.
Thus, if you have a quilt top that is 80 inches per side, you need at least 240 (+27) inches for the back. Ideally you want this in three 89" lengths.
