How this epoxy resin volume calculator works

Rectangular volume is length × width × depth in cubic inches. The calculator adds extra allowance and converts volume to liters, US gallons and fluid ounces.

How to use it

  1. Pour length. Enter the value in in.
  2. Pour width. Enter the value in in.
  3. Average pour depth. Enter the value in in.
  4. Extra allowance. Enter the value in %.
  5. Request the result. Add your email, then select “Email & show my result.”

What to do with the number

Voids, live edges, porous surfaces and mixing-cup residue can increase resin consumption. For deep pours, follow the resin manufacturer’s maximum pour depth and cure-temperature guidance rather than treating volume as the only constraint.

Planning estimate

Use this result as a starting point, not a guarantee. Product specifications, site conditions, manufacturer guidance, local codes, taxes, labor, tolerances, and rounding can change the real requirement or cost.
