About this calculator
Estimate cord length from a rough project-type multiplier, strand count and an extra allowance. These multipliers are planning heuristics, not a cut list for a particular knot design. Cord thickness, knot spacing, tension and finishing affect actual use; the spool estimate assumes 100 m per spool.
Worked example
calculated with the default values below
Project type Wall hanging · Finished length 30 in · Number of strands 16 · Extra for fringe and tying 25 % · Price per metre 0.8 $ Length per strand 150.0 in · Total cord length 2,400 in · Total cord length 60.96 m · 100 m spools (assumed package size) 1 · Cord cost 48.77 $

These calculators provide planning estimates only. Building codes, wiring regulations and safety requirements differ by country and change over time, and nothing here replaces a licensed professional or a permit. For structural, electrical or gas work, follow local code and have the installation inspected.
Implementation source
This record describes the implementation used by this page. It is not independent validation. External references, when available, support only the stated formula or definition; estimates and custom rules retain their own assumptions.
Formula and variables
perStrand = L × f × (1 + g ÷ 100); totalLength = perStrand × n
- L
- finished length (in)
- f
- cord factor by project type
- g
- extra for fringe (%)
- n
- number of strands
- m
- total cord length (m)
- spools
- 100 m spools needed
Factors are rough planning heuristics (keychain 3, dreamcatcher 4.5, wall hanging 4, plant hanger 5, bag 6). Spool count assumes 100 m; actual use depends on cord and knot pattern.
Frequently asked questions
How accurate are the cord multipliers?
The 3-to-6-times factors are rough planning heuristics, not a cut list for a specific knot pattern. Real usage changes with cord thickness, knot choice and spacing, tension, and finishing tails. The spool count assumes 100 m per spool. Make a sample section and adjust for your project.
