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.

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.

\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.

\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.

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