Inkle Band Width Calculator

Estimate warp ends for a target width, or check the width of a planned band.

Units
Start with your yarn

Use the same yarn, tension and finishing as your planned band.

Match a pattern repeat

Optional: adjust to complete repeats and keep your border ends.

How it's calculated

40 ends ÷ 1 in = 40 ends / in 1.5 in × 40 = 60 unrounded ends Nearest whole end: 60

An estimate, not a fit guarantee. Test a sample before choosing buckle or clasp hardware. Width follows your sample's finishing state.

Why a woven sample is the best starting point

Your yarn, tension and finishing all affect the final width. Measure a relaxed sample after the same finishing you plan for your band. Divide its warp ends by its width, then multiply that density by your target width. If edges pull in or waver while weaving, see our selvedge troubleshooting guide.

Without a sample, tight WPI × 2 is a rough estimate for warp-faced plain weave. It is not the sett for balanced cloth, and it does not model tablet weaving, pickup with mixed yarn sizes or bands made with different tensions.

Example: a 40-end sample measuring 1 inch suggests 60 ends for 1.5 inches. With 8-end repeats and 4 border ends, 7 complete repeats still give 60 ends. Weave a test before committing to hardware.
