Wire Length Calculator — Jewellery Wire Needed
Calculate wire length needed for wraps, coils, frames and jewellery findings.
Diameter of bead, mandrel or frame
Extra for tails and trimming
How We Calculate This
Wire length for wraps and coils is calculated using the circumference formula: length = pi x (object diameter + wire diameter) x number of wraps.
For frames, the perimeter (circumference for round objects) is used. Bail length includes the loop plus a 20 mm tail for securing.
The optional 15% extra accounts for tail ends, tool grip and trimming waste.
