Work out wire length for jewellery instantly with clear inputs, formula shown and shareable results.
Wire use is loops times wire per loop times the number of wraps, with a waste allowance added for the tails trimmed off each piece. Trimmed tails are pure loss on precious metal wire, which is why the waste percentage matters as much as the design length.
Wire length
cm = loops x wire per loop x wraps x (1 + waste allowance)
cm = loops x wire per loop x wraps x (1 + waste allowance). Wire use is loops times wire per loop times the number of wraps, with a waste allowance added for the tails trimmed off each piece.
Trimmed tails are pure loss on precious metal wire, which is why the waste percentage matters as much as the design length.
Enter number of loops or links, wire per loop, wraps per loop, waste allowance. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
