What is paracord bracelet length calculator?
This calculator estimates cord length for woven paracord bracelets. Different weaves consume very different amounts of cord per finished inch, so choosing the pattern matters as much as wrist size.
How to use this calculator
- Measure wrist size and add comfort ease.
- Pick the weave pattern.
- Enter the number of colors.
- Cut each color using the per-color estimate.
How is it calculated?
Formula
total cord = finished bracelet size x cord per inch by weave x 1.15 waste factor What The Constants Mean
- Cobra weave (12): Common rule of thumb: about 1 foot of cord per finished inch.
- King cobra weave (24): Uses about twice the cord of a cobra weave because it wraps over a finished base.
- 15% extra (1.15): A more generous planning buffer for cord, dye, yarn, or thread where leftovers are easier than running short.
An 8 in cobra bracelet uses about 110 in of cord after adding a 15% waste allowance.
Common mistakes
Many beginners measure the wrist but forget the buckle, knot compression, and cord consumed by finishing knots. Dense weaves also use dramatically more cord than simple fishtail designs.
