How much wire do I need for a simple wrap pendant?

For a simple wrap around a 30–40mm stone, you typically need 60–80cm of frame wire and 100–150cm of wrapping wire. Beginners should add 20–30% extra for mistakes. The exact amount depends on stone shape, depth and how tightly you wrap.

What wire gauge should I use?

Use 0.8–1.0mm (18–20ga) for the frame that holds the stone, and 0.4–0.6mm (22–26ga) for the wrapping wire. Thicker frame wire gives more structure, while thinner wrapping wire is easier to weave and coil around the frame.

Does stone shape affect wire usage?

Yes. Freeform and irregular stones need more wire because the wrap must follow an unpredictable outline. Round and oval stones are the most efficient. Teardrop stones need extra wire at the pointed end. Always measure the actual stone perimeter if possible.

What wire material is best for beginners?

Start with copper wire — it is affordable, easy to work with and widely available. Once you have confidence, move to sterling silver or gold-filled wire. Aluminium is soft but does not take a polish. Brass is affordable but harder to bend than copper.

How We Calculate This

This calculator estimates wire length based on stone dimensions, wrap style complexity and bail requirements.

Calculation method

Stone perimeter is calculated from height, width and depth using the appropriate shape formula.

Frame wire = Perimeter × 2.5 (enough for a double frame with overlap)

Wrapping wire = Perimeter × Style multiplier

Simple wrap: ×3
Criss-cross: ×4.5
Woven: ×5
Coil: ×6
Tree of life: ×7
