How to Calculate Fabric for A Quilt?

Calculation of fabric for a quilt mostly depends on your design, pattern, and size requirement. For example, suppose you need a 5×5 sq. inches of cloth shaped like a square.

Hence the fabric needs to be cut in the size of 5.5″ from both length and width. Note that your block size is critical. But along that, you need to add a seam allowance of ¼ inches to each side.

So, let’s get you to the calculation steps:

Step 1:

First, measure the width and divide its value by your block size.

Assume your fabric is 55″ in width. So, divide it by 5.5″. Thus, you can fit 10 blocks across the width of your fabric. If the math yields, not a whole number, round it down. For example, if it’s 7.8, use 7.

Step 2:

Take the total number of blocks you need depending on your pattern and divide it by the obtained blocks number you get to fit in width.

We think that you need 22 blocks in total. Next, divide it by 10. It results in 2.2. Let’s round it up to the closest whole number. Here it’s 3. So, you need to cut down three strips of your fabric to fit enough blocks. 

Step 3:

Now multiply the width of each block with the total number of strips needed.

For our case, 3 strips times 5.5″ width yields a total of 16.5″ fabric.

Hence, we say, to cut out 22 5.5′ squares of cotton fabric of 55″ in width, you need around 16.5″ of quilt fabric, taking the hem edges into account.

You can hop to the last calculation step if you already have an evenly cut fabric for your quilt.
