Macrame Cord Length Calculator

Enter the finished length, number of cords, and multiplier to get cord length.

How it is calculated

The length to cut for each cord is per_cord = finished × multiplier × (2 if folded, else 1), with the finished length in centimetres. The total is total = per_cord × cords, shown in centimetres and in metres (total divided by 100).

Multiplier is how many times the finished length you cut; if left blank the tool uses 4. Denser knotting uses more cord per centimetre of finished work, so choose a higher multiplier for tightly knotted patterns. Set fold to yes when each cord is folded in half and mounted with a lark's head knot: the cut length doubles, and the cords field then means the number of folded cords you mount. Finished length, cord count and multiplier must be above zero. The estimate does not add allowance for fringe or tails.

Worked example

You want a wall hanging 80 cm long, with 12 mounted cords, a multiplier of 5 and folded cords. One cord needs 80 × 5 × 2 = 800.00 cm, which is 8 m cut length per cord. For 12 cords the total is 800 × 12 = 9,600 cm, or 96.00 m. Without folding, the same inputs would give 400 cm per cord and 48 m in total, so the fold setting alone halves or doubles your shopping list.

Common mistakes

  • Entering the finished length in inches or metres. The field is centimetres; 0.8 for 80 cm would give a cord length of just a few centimetres.
  • Counting strands instead of mounted cords. With fold set to yes, the tool already doubles each cord, so enter 12 mounted cords, not 24 strands, or the total is doubled twice.
  • Forgetting to switch fold on when you do fold the cords. The result is then half the cord you actually need.
  • Using the default multiplier of 4 for a dense pattern. Tight spirals and many square knots eat more cord, so the project can run short.
  • Ignoring the length of the fringe. The multiplier covers knotting, but if you want long tails beyond the finished length, add them separately.

About this calculator

Macrame patterns typically call for cutting each cord to roughly 4 to 6 times the finished project length — the rule-of-thumb multiplier this calculator applies — because knotting (square knots, half hitches, spirals) consumes far more cord than the flat distance it covers; denser knot patterns need a multiplier toward the higher end of that range.

For cords that are folded in half and mounted onto a ring or dowel with a lark's head knot, the calculator doubles the per-strand length before totaling, since each mounted cord actually uses two working strands. Macrame crafters and fiber artists use this before cutting to avoid running short mid-project or wasting cord by over-cutting.

    The multiplier is the part worth testing yourself. Knot a 10 cm sample in your own pattern, measure how much cord one strand used, and divide by 10 to get your own multiplier. Measure a single strand, since the fold setting doubles the cut length for you. Tighter, more complex knotting will come out higher than a loose design. Which knot pattern do you work in, and what multiplier ended up working?
