How to use the Paracord Bracelet Calculator
Measure your wrist snugly with a soft tape, or wrap a paper strip and measure it flat.
Choose the fit: most people like about 1 in of extra room.
Pick the knot style and cord type.
Read the cord length to cut and the knotted length to set between the buckle halves.
Check the buckle size and the two-color split if you are using two colors.
Paracord length formula
Cord length = (wrist + fit allowance) × cord per inch of weave + finishing allowance
Example: a 7 in wrist with a comfortable fit is a 7 + 1 = 8 in knotted length. A cobra weave uses about 12 in of cord per inch, so 8 × 12 = 96 in, plus 6 in for trimming and melting = 102 in, or 8.5 ft (about 2.6 m).
Lengths include 6 in for finishing. Rates are rules of thumb (cobra about 1 ft per inch, king cobra about 2 ft, fishtail about 1.25 ft); tight tiers use a bit more.
Tips
Cut a little long the first time. Leftover cord makes zipper pulls and keychains, while a short cord means starting over.
Pull every knot to the same tension so the bracelet stays straight and matches the measured length.
Seal cut ends of nylon paracord by carefully melting them with a lighter and pressing flat with the side of the lighter (ask an adult to help if you are young).
To measure your own rate, tie exactly 1 in of weave on a marked length of cord, untie it and measure what was used.
Frequently asked questions
How much paracord do I need for a bracelet?
A common rule for the cobra (Solomon bar) weave is about 1 ft of 550 paracord for every inch of bracelet. A 7 in wrist with 1 in of room is an 8 in bracelet, so you need about 8 ft, plus roughly 6 in for finishing.
How much paracord does a king cobra bracelet need?
A king cobra is a second layer of cobra knots tied over a first one, so it uses roughly twice as much: about 2 ft per inch. An 8 in king cobra bracelet needs about 16–17 ft of cord.
How much paracord for a fishtail bracelet?
A fishtail weave typically uses about 1 to 1.5 ft of cord per inch, depending on how tightly it is packed. The calculator uses 1.25 ft per inch; measure your own rate for a more exact figure.
How do I size a paracord bracelet?
Measure your wrist snugly, then add about 1 in for a comfortable fit (1/2 in for snug, 1 1/2 in for loose). Set that distance between the inside ends of the two buckle halves before you start knotting.
What size buckle should I use for a paracord bracelet?
For a cobra bracelet in 550 paracord, a 5/8 in side-release buckle is the usual choice. King cobra bracelets look better with a 3/4 in or 1 in buckle, while 325 cord suits 1/2 in and micro cord suits 3/8 in buckles.
How many bracelets can I make from 100 ft of paracord?
With about 8.5 ft per cobra bracelet you can make around 11 bracelets from a 100 ft hank, or about 6 king cobra bracelets.
Does thinner cord need more length?
Not much per inch: thinner cord packs more knots into each inch, but each knot uses less cord, so the length per inch stays roughly similar. The finished bracelet is narrower, so use a smaller buckle.
