The Quilt Backing Calculator helps quilters determine the amount of backing fabric needed to complete their quilts. It accounts for the extra inches typically required for quilting, making it easy to calculate the necessary fabric length in yards.
Explanation and Background
Quilting requires precision in measuring and cutting fabric, especially for the quilt backing, which needs to be larger than the quilt top to accommodate quilting and any potential shifting. This calculator helps you figure out exactly how much backing fabric is needed, avoiding both excess and shortage.
Calculation Formula
The backing fabric length is calculated by adding 4 inches to each side of the quilt dimensions, then determining the number of fabric widths required. The total length of fabric needed is then adjusted into yards.
Example Calculation
If your quilt is 60 inches wide by 80 inches long, and the backing fabric is 44 inches wide:
- Total quilt width = 60 + 8 = 68 inches
- Total quilt length = 80 + 8 = 88 inches
- You will need 2 widths of fabric, each 88 inches long.
Convert the length to yards:
- Backing fabric length = 88 inches / 36 = 2.44 yards (rounded to 2.5 yards).
Thus, you would need 5 yards of backing fabric.
Importance and Usage
Calculating the correct amount of backing fabric is crucial for ensuring that your quilt comes out perfect without running short on fabric. This tool is particularly useful for those working on larger projects or using fabric with a directional print.
Common FAQs
-
Why do I need extra fabric for quilt backing?
- Extra fabric is needed to account for the quilting process, which can cause the fabric to shift and shrink slightly.
-
Can I piece together smaller fabric widths for backing?
- Yes, piecing together smaller widths is common, especially when using fabric that is less than 108 inches wide.
-
What should I consider when choosing backing fabric?
- Consider the fabric width, print direction, and whether the fabric color and texture complement your quilt top.
This calculator simplifies the process of determining the amount of fabric needed, saving time and ensuring that your quilt backing is sufficient for your project.
