What is macrame cord length calculator?
Macrame uses far more cord than the finished length because knots consume material. This calculator gives a planning estimate based on project length, knot density, and number of working cords.
How to use this calculator
- Enter finished project length.
- Choose knot density.
- Enter working cord count.
- Cut cords using the per-cord suggestion and trim after finishing.
How is it calculated?
Formula
cord length = finished length x knot density multiplier x project factor What The Constants Mean
- Medium knot density (6): Middle estimate for common plant hangers and wall hangings.
- Wall hanging factor (1.1): Adds a modest allowance for fringe and layout variation.
- 10% extra (1.1): A small planning buffer for trimming, cup residue, uneven edges, and measurement variation.
A 36 in medium-density wall hanging may need about 238 in per cord before final trimming.
Common mistakes
Tight knotting, spiral knots, and plant hangers can consume extra cord. If you are new to a pattern, cut longer and save leftovers for fringe, samples, or keychains.
FAQ
How much cord does macrame use?
Loose work may use about 4 times finished length, while tight knotting can use 8 times or more.
Should all cords be the same length?
Not always. Pattern-specific cords can vary, but equal cuts are a good planning start.
Does cord thickness matter?
Yes. Thicker cord can change both look and consumption.
Why add extra?
Extra length protects against tension changes and finishing knots.
