Guide
This guide answers the broad quantity question first, then points you to the right calculator for the job. The main mistake people make is treating every epoxy project like the same geometry problem.
Direct Answer
You need enough epoxy to cover the raw project volume or surface thickness, plus realistic extra material for waste, seepage, edge loss, and safety margin. The correct tool depends on whether your project is a cavity, a coating, a deep cast, or an irregular live-edge pour.

FAQ
It is designed for planning and procurement, not for replacing the manufacturer data sheet. The calculator is most useful when you add the right waste buffer and choose the page that matches your project type.
Real projects lose material to mixing cups, edge soak-in, seepage, and safety margin. Raw volume alone is often too optimistic.
Yes. Always confirm maximum pour depth, cure conditions, and mix ratio with the product documentation you plan to buy.
