Estimate resin volume for rectangular pours, tabletops, round molds, coasters, and river table sections with mix ratio and waste allowance.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

Rectangular and round pours are calculated in cubic inches, then converted to US fluid ounces for common resin measuring cups.
fluid ounces = cubic inches x 0.554113Total epoxy volume is split into resin and hardener by the selected volume ratio, such as 1:1 or 2:1.
The Epoxy Resin Calculator calculates raw material needs from project dimensions and repeat pattern spacing. Shrinkage, kerf, and trim allowances are included where applicable.
Material = Project Area × (1 + Waste Factor)Updated: July 2026
Enter length, width, and shallow pour depth to estimate resin before starting the mix.
Switch to round shape, enter diameter and depth, and add waste for cup residue and overfill.
A hobbyist enters measurements into the Epoxy Resin Calculator before buying yarn, filament, or resin to avoid mid-project shortages.
Live-edge tables, cracks, and knots rarely match perfect geometry. Measure actual voids and keep extra resin ready.
Follow the manufacturer maximum pour depth and working time to avoid overheating, bubbles, or a soft cure.
Estimate how much epoxy to mix before a pour. Enter shape, dimensions, pour depth, mix ratio, and waste allowance to get total fluid ounces, gallons, liters, resin side, and hardener side.
