Calculate kumihimo cord length from your finished braid length, strand count and take-up factor – get cut length per strand, total cord needed, and bead counts.

Length of braid you want after finishing, not counting clasps or end caps.

Sets the strand count and the starting take-up factor.

Extra on every strand for knots, bobbins and trimming.

Kumihimo Length Formula

The following rule-of-thumb formula is used to estimate the cut length required per strand for a Kumihimo braid using a take-up factor (multiplier).

SL = FL × TF

Variables:

  • SL is the cut length per strand (use any length unit, as long as you’re consistent)
  • FL is the finished length of the braid (same unit as SL)
  • TF is the take-up factor (unitless multiplier). Typical starting points: TF ≈ 3 for an 8-strand round braid; TF ≈ 4 for a flat braid (varies by materials, tension, and pattern).
  • After calculating SL, it’s common to add extra length per strand for finishing (knots, braiding waste, and handling).

To estimate the cut length per strand, multiply the desired finished length by a take-up factor appropriate for your braid type and materials. Because take-up depends on pattern, tension, and cord type, this is an estimate—when in doubt, cut longer and add an extra allowance for ends.

What is Kumihimo?

Kumihimo is a traditional Japanese form of braid-making. Cords and ribbons are made by interlacing strands of threads, which can be made of various materials such as silk, cotton, or synthetic fibers. Kumihimo braids are often used in jewelry making, decorative arts, and traditional Japanese garments.

How to Calculate Kumihimo Length?

The following steps outline how to estimate the cut length needed for a Kumihimo braid.

  1. Determine the desired finished length of the braid (FL) in a convenient unit (in, cm, etc.).
  2. Choose a take-up factor (TF) based on your braid type/materials (or measure TF from a short test braid).
  3. Use the formula SL = FL × TF to estimate the cut length per strand (SL).
  4. Add an extra allowance per strand for finishing (knots/closures and handling), if needed.
  5. Check your answer with the calculator above (the “Cord Cut Length” tab includes an optional extra allowance).

Example Problem : 

Use the following variables as an example problem to test your knowledge.

desired finished length of the braid (FL) = 20 inches

take-up factor (TF) = 3

Using SL = FL × TF: SL = 20 × 3 = 60 inches per strand (then add extra allowance for ends/finishing if needed).
