Enter your project dimensions to calculate epoxy volume and waste allowance, then compare the result with verified Magic Resin 2 in and 4 in Deep Pour guidance. EpoxyCalc is independent and is not affiliated with or operated by Magic Resin.
Calculate quantity first. Product matching only uses verified manufacturer data.
Compatibility below uses the verified Magic Resin 2 in Deep Pour product. If your planned layer exceeds 2 inches, review the separate 4 in product and the current manufacturer instructions.

Magic Resin publishes separate deep-pour systems for projects up to 2 inches and up to 4 inches in a single pour. The calculator above is pre-filtered to the 2 in product because it is the more conservative default for river-table planning; the table below lets you compare both verified products before ordering.
| Product | Max single pour | Mix ratio | Recommended temperature |
|---|---|---|---|
| Magic Resin 2 in Deep Pour | 51 mm / 2.00 in | 2:1 by volume | 21–24 °C |
| Magic Resin 4 in Deep Pour | 102 mm / 4.00 in | 2:1 by volume | 21–24 °C |
The calculator uses the cavity volume from length, width and depth, then adds the waste allowance you choose. This is more useful than guessing from surface area for river tables and castings because deep-pour projects are three-dimensional.
The verified 2 in and 4 in systems both use a 2:1 resin-to-hardener ratio by volume, with 100:45 also published by weight. Keep the measurement basis consistent. For splitting a batch into exact resin and hardener amounts, use the resin and hardener ratio calculator.
A larger kit does not mean a deeper safe pour. Product formulation, project mass and temperature determine the published depth guidance. If a project is close to a maximum depth, verify the current Magic Resin instructions before mixing.
EpoxyCalc stores verified kit sizes for both Magic Resin systems. Product matching can therefore compare your calculated quantity with real kit volumes instead of simply rounding to an arbitrary number of gallons.
