StitchTip calculator
Increase rate calculator
Use the increase rate calculator to turn your own measurements into a clear, editable result.
How this tool works
Enter the measurements shown in the form and calculate the result. Whole items are rounded only when they must be purchased or made as complete units; estimates remain clearly labelled.
Example calculation
Start with the prefilled example, then replace every value with measurements from your own yarn, swatch, project, time or selling costs.
Frequently asked questions
How accurate is this result?
Arithmetic results follow the entered values. Yarn, geometry and time estimates are only as accurate as the measurements and assumptions you provide.
