Mold Volume Calculator

Work out the volume of a silicone or wooden mould from its shape and dimensions, and how many millilitres of resin it holds.

Mould shape

Outer length cm

Rectangular moulds only. Measure the outside.

Outer width cm

Rectangular moulds only.

Outer diameter cm

Circular and cylindrical moulds.

Outer depth cm

Wall thickness mm

One wall, not both. The tool subtracts a wall from each side and a base from the bottom. Enter zero if you measured the internal faces directly.

Base thickness mm

The floor of the mould. Enter zero for an open frame on a flat surface.

How many cavities?

Resin density g/ml

About 1.05 to 1.2 grams per millilitre for most epoxy products.
