About ResinCalcs

ResinCalcs offers free online calculators for people who work with epoxy and casting resin: woodworkers building river tables, makers pouring tabletop coatings, and crafters filling moulds.

Resin is expensive and mistakes are hard to undo, so each calculator shows its formula and a worked example. That way you can see how the answer is reached instead of trusting a black box.

The calculators give estimates. Resins differ in density, maximum pour depth and mix ratio, so always follow the technical data sheet from your manufacturer.
