Resin Calculator: Epoxy Mix

Resin Calculator takes the guesswork out of every pour. Enter your mold or piece dimensions and get the exact amount of resin to mix — total, Part A, and Part B — so you never mix too much or come up short. Built for epoxy and casting resin, jesmonite, doming, and coating work. FEATURES - Volume by shape — box, cylinder, dome, coating (area × thickness), or enter a volume directly - Part A / Part B breakdown for any mix ratio — 1:1, 2:1, 3:1, 4:1, or custom - Mix by volume OR by weight — clearly labeled every time, because the two are NOT interchangeable - Results in both volume and weight at once - Adjustable resin density and a waste / overage buffer - Metric and imperial units PRIVATE & OFFLINE Works 100% on your device. No account, no internet, no data collected — ever. Estimates only — always follow your resin manufacturer's mixing instructions.
