# Your question: How do I figure out how much fabric I need for the back of a quilt?

Contents

## How many yards do I need to back a quilt?

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. 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.

## How many yards do I need for backing?

The amount of yardage needed is rounded up to the nearest eighth of a yard. For example, suppose the backing you need for a quilt is 52 inches wide by 96 inches long and the fabric you wish to use for the backing is on a bolt of fabric whose width is 43 inches. The yardage required is 5 1/3 yards.

## How much bigger should the backing be than the quilt top?

Size of the back: must be at least 6″ wider on each side, top and bottom, than your quilt top. A total of 12″ larger than your quilt top. Trim the top and bottom edges of your backing so they are straight and square.

## How much material do I need for the backing of a queen size quilt?

The total yardage needed for a queen size quilt varies with the pattern and fabric used. A standard queen size quilt that is 88 inches wide and 96 inches long takes about 8 yards of fabric for the front of the quilt and another 8 yards of fabric for the back of the quilt, depending on the pattern and fabric you choose.

## How many yards of fabric do I need to back a twin quilt?

For example, with a 14-inch drop, a twin quilt typically is 70 inches wide and 90 inches long. Seventy multiplied by 90 equals 6,300, plus 20 percent equals 7,560, divided by 1,296 equals 5.8, rounded up is 6. Each of the top and underside requires a minimum of 6 yards of fabric.

## Should the batting be the same size as the backing?

The batting also needs to be larger than the top but not larger than the backing. I can always trim the batting if it is too large but harder to make it bigger if too small, although I have pieced batting together as needed with satisfactory results it is always best to do that before sending it to the longarm quilter.

## Do I quilt or bind first?

Binding a quilt is the final step in finishing. Before you bind, you need to somehow “quilt” your quilt. This means to attach the front and back, with batting in between.
