Wire Length Calculator

Work out the wire needed for wrapped loops, coils, chain links or rings, from the dimensions and the wire gauge, with a waste allowance.

What are you making

Each shape uses a different amount of wire for the same size.

Wire gauge

The diameter is what the arithmetic uses, so the chart above gives it in millimetres.

Metal

Used for the weight estimate only. Prices move with the metal market, so cost is worked out from the price you enter.

How many pieces

Loops, coils, links or rings, depending on what you are making.

Bead, mandrel or link diameter mm

The mandrel diameter for a coil, the loop diameter for a loop or a ring, the link size for a chain.

Wire price per metre USD/m

Optional. Divide the price of your coil by its length to get this figure.

Waste allowance %

Covers filing, ruined loops and work hardened wire that cannot be reused.
