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.

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.
