Wire-Wrap Stone Cage Calculator
A cage wrap has several strands running around the stone, each looped a few times to lock it in place. Total length is circumference times strand count times wrap multiple, plus a tail left over for the finishing bend.

Formula
Total wire needed = Stone circumference × Cage strands × Wrap multiple + Finishing tail length
Irregular stones have a circumference that varies by where you measure, so add about 20% margin. On a first attempt, cut long and trim the excess rather than cutting short.

Frequently asked questions
QHow is Wire-Wrap Stone Cage Calculator calculated?
Total wire needed = Stone circumference × Cage strands × Wrap multiple + Finishing tail length — A cage wrap has several strands running around the stone, each looped a few times to lock it in place. Total length is circumference times strand count times wrap multiple, plus a tail left over for the finishing bend.
QCan you walk through an example?
With Stone circumference 6cm, Cage strands 4strands, Wrap multiple 3×, Finishing tail length 15cm, the answer is Total wire needed 87cm.
QWhat do I need to enter?
Enter Stone circumference, Cage strands, Wrap multiple, Finishing tail length. The result recalculates as you type, and an empty box counts as zero.
QHow much does the answer move if I change a number?
Changing only Stone circumference (cm) moves the answer to Stone circumference (cm) 3 → Total wire needed (cm) 51 and Stone circumference (cm) 12 → Total wire needed (cm) 159. The table below lays out five steps.
QHow are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
QAnything to watch out for?
Irregular stones have a circumference that varies by where you measure, so add about 20% margin. On a first attempt, cut long and trim the excess rather than cutting short.
