Meniscus: Resin Calculator

Free resin calculators that get the math right — coverage, deep pour, mix ratio, pigment. Now track your stock and price every piece from real costs with Pro.

Meniscus is the resin calculator that gets the mix right.

Whether you're flood-coating a tabletop, casting tumblers and molds, or pouring a live-edge river table, Meniscus does the resin math for you — the exact resin and hardener, the mix ratio, the coverage and volume, the pigment, and the cost. No more guessing, no more half-cured pours or wasted, expensive resin.

EVERY CALCULATOR IS FREE • Coverage / Flood Coat — how much resin to cover any area at any thickness, split into Part A and Part B. • Deep Pour / Casting — volume for any mold shape, with resin + hardener. • River Table — average an irregular live-edge channel from as many width measurements as you take. • Mix Ratio — exact Part A + Part B by volume or by weight, for any ratio (1:1, 2:1, 3:1, custom). • Pigment — how much mica or dye by weight, plus seal and dome coats.

Every result shows its work — the ratio, the waste buffer, the cost, the rounding — because a resin calculator you can't trust is worse than none.

DESIGNED LIKE A MAKER'S STUDIO Clean, calm, and precise. Monospaced numbers, a fill-level read on every pour, one accent of cured-resin teal. Fluid ounces, gallons, milliliters, liters, or grams — pick once, and every number on every screen follows. Volume to weight by density, both ways.

YOUR STOCK ROOM (PRO) Track every material you own — resin, hardener, pigment, mica, molds, supplies — with what's on hand and what each costs, plus a low-stock heads-up before a pour. Link a project's materials to your stock and every piece prices itself from your real unit costs — change a price once and every project follows. Cast a batch? "Poured a batch" counts your stock down automatically, with shortfall and low-stock flags.

MENISCUS PRO Save your pours into projects, keep a material list for each one, and price your finished pieces — material + labor + markup gives a suggested sale price you can take to your shop. Track your supply stock and let it cost every piece. Export the list to take shopping. Pro is optional — Monthly, Yearly, or a one-time Lifetime unlock. The calculators are, and always will be, free.
