Heel turn calculator

Heel turn calculator

Have you ever racked your brain trying to figure out the numbers when knitting the heel of your sock? I know I have. This heel turn calculator can do the math for you! Just pop your numbers into the form and select the type of heel you’d like and it will generate instructions for you.

I designed this heel turn calculator to calculate the heel turn of a top down sock with heel flap. I’m also working on a calculator to calculate the heel turn of a Fleegle heel and one that will generate complete sock recipes, so please subscribe to my newsletter if you’d like to know when these are available.

Don’t hesitate to reach out if you have any problems using this calculator.

Have fun turning those heels!
