How our fabric yardage calculator works

Our fabric calculator allows you to enter the width of the fabric you are working with, the length, width, and the number of pieces you need for your project, and in return it:

  • Gives you the smallest amount of fabric you can buy for your project; and
  • The number of pieces you should cater for across and lengthwise.

This type of calculator is best used for home improvement projects that use geometric shapes rather than clothes. You may consider using it as a table cloth or quilt fabric calculator where you wish to produce multiple pieces of these items using a standard measurement.

If you are interested in these types of projects, our tablecloth size calculator, curtain panel calculator, and quilt calculator may interest you too.

Our yards of fabric calculator's formulas

In calculating the total yards of fabric, you will need for your project, our yards of fabric calculator takes the width of the material you enter and divide it by the width of the fabric you wish to cut. This gives us the number of pieces you will have across.

pieces across=fabric width/width to cut\text{pieces across} = \text{fabric width}/\text{width to cut}

Next, we round down because there can be leftover fabric when we calculate the total number of pieces across, and we do not wish to use any halves or quarter pieces.

To figure out the number of rows down, we divide the total number of pieces you wish to cut by the number of pieces across.

rows down=pieces to cut/pieces across\text{rows down} = \text{pieces to cut}/\text{pieces across}

Lastly, we calculate the yards of material needed by multiplying the length of the piece you wish to cut by the number of rows down.

material needed=length to cut×rows down\text{material needed} = \text{length to cut} \times \text{rows down}


How do I calculate the amount of fabric needed for 120 napkins?

To calculate the amount of fabric you will need for 120 napkins, complete the following steps:

  1. Divide the width of the fabric you are using by the width of the napkins;
  2. Round down to the nearest integer number;
  3. Divide 120 by your answer from step 2; and
  4. Multiply the answer you got in step 3 by the length of the fabric for each napkin.

The answer you got in step 4 is the smallest amount of fabric you can buy for your project.

How many yards are there in a bolt of fabric?

A bolt of fabric may range from 30 to 100 yards.

A bolt is not a typical unit of measurement. While we talk about a bolt of fabric as though it has some specified dimensions, it varies. The bolt size is more dependent on the thickness of the material than the length.

How many square feet are in a yard of fabric?

A piece of fabric that is 60 inches (5 feet) wide and 1 yard (3 feet) long will have 15 square feet.

However, the width of fabric varies, so not all materials will have 15 square feet in a yard.

How big is a yard of fabric?

A yard of fabric is 36 inches or 3 feet.

Once you know the amount of material you have in inches, you should divide that by 36 to find the number of yards.
