Leather Yield Calc
Estimate usable hide area, pattern-piece area, waste, and material cost for small leatherworking projects.
How the app works
The app processes entered hide, yield, pattern, piece-count, waste, and price values on the device. It does not create an account, send calculation data to a server, or provide cloud storage.
Support scope
Support covers using the calculator, understanding the displayed inputs and results, and removing local app data. The app has no sign-in, subscription, advertising, third-party analytics, or backend service.
Important limits
This is a material and quote-planning tool only. It does not replace hands-on pattern layout, supplier grading, or leatherworking judgment.
