Epoxy Volume Calculator
Estimate the mixed epoxy needed for a pour, filled hole, channel or coating.
What the result means
This is the total mixed volume, not the amount of resin or hardener by itself. Once you know the mixed amount, use the product ratio to divide it into Part A and Part B.
Formula
Rectangular volume = length × width × depth
Circular volume = π × radius² × depth
Common mistakes
- Measuring an uneven void as though it were perfectly rectangular.
- Using the mixed total as the amount of each component.
- Ignoring epoxy absorbed into porous wood.
- Pouring deeper than the product allows.

Volume does not tell you how to pour it
Deep pour epoxy, coating epoxy and casting resin have different limits. Follow the product instructions for mix ratio, pour depth, temperature and cure time.
