Calculate kumihimo cord length per strand from your finished braid length and braid style, with total cord to buy and bead counts for beaded braids.

Excludes clasps and end caps. In test mode, leave blank to skip the project estimate.

Cord used per strand ÷ braid length. The braid setup fills a typical value; edit it if yours differs.

Extra cord per strand for knots and finishing. Starts at a typical 6 in; blank means zero.

Waste, cutting, spools and size
Added to total cord for purchase, not to each cut. Blank means zero.

Blank omits spool and cost estimates. Each cut must fit one spool.

Blank omits cost; requires a spool length.

Optional, for a rough finished braid size. Measure the braid before buying end caps.

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 + A

Variables:

  • SL is the cut length per strand including finishing allowance A (use consistent units)
  • 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).
  • A is the total finishing allowance per strand for knots, braiding waste and handling. The calculator includes it once; do not add it a second time.

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. The 3× round-braid rule is a starting point; see Needlery’s braiding guide. Other source presets and bead/size heuristics are assumptions, not guarantees. Manufacturer bead counts vary by size and shape; see MIYUKI size and bead-count data. Measure a sample and the finished braid before selecting end caps.

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 SL = FL × TF + A to include the finishing allowance once.
  4. Select finishing allowance A for your knots/closures and handling. The preset 6 inches is only a starting allowance.
  5. Check the Cord to cut result, purchase reserve and cut plan. Measure take-up from a test braid, then select Use test measurements in either project mode to reuse the inputs.

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

With A = 0, SL = 20 × 3 = 60 inches per strand. With A = 6 inches, cut 66 inches per strand. Total cut cord for eight strands is 528 inches, before any purchase buffer.
