Start with eyelet pairs and shoe type. This is an estimate: width, spacing and lacing style change the length you need.
Initial estimate
31" – 35"
General guide: the exact length depends on shoe width, eyelet spacing and lacing style. For production runs, confirm with a physical sample.
Test the length on your footwear, measure tip to tip and document the approved sample along with its profile, color and finish.
Prepare the full specification →Count the holes on one side of the shoe: that number is the pairs. A typical sneaker has 5–6 pairs; a work boot 7–9, sometimes with hooks at the top.
Too short: no firm tie and bad knots. Too long: it hangs, gets stepped on and wears out early. For production runs, confirm the length with a physical sample on the actual shoe.
The calculator provides an initial estimate. Check the selected catalog reference and share the finished length required by your footwear for manufacturing review.
