Weaving Calculators & Viewers

Free browser tools for planning and inspecting weaving projects. Nothing to install, nothing uploaded.

WIF Viewer

Open a .wif weaving draft in your browser to see the threading, tie-up, treadling, and colored drawdown. Download an image or open it in Bower.

Sett Calculator

Turn wraps per inch and a weave structure into a recommended sett (ends per inch), a firm-to-open range, and reed options.

Warp Calculator

Get total ends, warp length, yardage, and yarn weight from your finished size, sett, take-up, shrinkage, and loom waste.

Yarn Count Converter

Convert between tex, denier, metric (Nm), cotton count (Ne), worsted, linen lea, and yards per pound. Decodes 8/2 style labels.
