Warp and Weft Calculator

A practical tool for weavers who want to plan and calculate with confidence.

Warp and Weft Calculator is a simple and practical tool for weavers who need to calculate warp, warp width, and weft.

The app helps you calculate length, weight, thread count, and density, and clearly indicates when values don’t match. You can leave one field empty and let the app calculate the missing value.

A built-in yarn catalog with common yarn qualities makes it easy to choose the right yarn. All values can be adjusted manually, and the app works completely offline.

Warp and Weft Calculator is designed as a planning aid — easy to use both in the weaving studio and at home.
