Bias Tape Calculator
Calculate how much fabric is needed to make bias tape and continuous bias binding
About this calculator
The Bias Tape Calculator helps sewers and quilters determine exactly how much fabric is needed to create bias tape and continuous bias binding for their projects. This tool eliminates guesswork and fabric waste by calculating the precise yardage required based on your desired bias tape width and total length needed. Whether you're binding quilts, finishing seams, or adding decorative trim, this calculator ensures you purchase the right amount of fabric and plan your cutting efficiently.
How to use
Enter the width of bias tape you want to create and the total length needed for your project. The calculator will determine how much fabric yardage you need to purchase. For continuous bias binding, also input your fabric width to get the most efficient cutting layout and minimize waste.
Frequently asked questions
What's the difference between bias tape and bias binding?
Bias tape is the strip cut on the bias, while bias binding refers to using that tape to finish edges or seams in sewing projects.
Why cut fabric on the bias for tape?
Bias-cut fabric has natural stretch and flexibility, allowing it to curve smoothly around edges and corners without puckering or bunching.
How much extra fabric should I buy?
Add 10-15% extra fabric to account for cutting waste, mistakes, and having spare binding for future repairs or matching projects.
