Exact resin amounts for any mold, mix ratio or flood coat. Weight and volume done right with real densities. No account, no ads, offline.
ResinTally is the resin calculator that gets weight vs volume right. Mold volumes, mix ratios, flood coats and real densities — built for the way epoxy actually cures.
Made for resin artists, epoxy crafters, jewelry makers and river-table builders who are tired of wasted resin and failed cures.
NEVER MIX TOO MUCH AGAIN
- 8 mold shapes: box, cylinder, sphere, dome, cone, oval, hexagon — or enter a volume directly
- Measured your mold with water? Type the milliliters straight in
- Waste buffer for cup residue and stir sticks, included in every number
- Batch multiplier for coaster sets and market stock
- Results in ml, fl oz and grams at the same time
WEIGHT OR VOLUME, DONE RIGHT
1:1 by volume is NOT 1:1 on a scale. Part A and Part B have different densities, and mixing a volume ratio by weight is the number one cause of sticky, uncured resin. ResinTally converts between the two with real densities, so the numbers on your scale are actually right.
- Any ratio: 1:1, 2:1, 3:1, 100:30 or fully custom
- Part A and Part B in milliliters AND grams, every time
- Verified presets for popular brands, plus your own custom resins
FLOOD COATS WITHOUT GUESSWORK
- Surface length x width at any thickness
- Or the classic tabletop rule built in
- Same waste buffer, same instant Part A / Part B split
