Calculate resin for cube molds, block castings, dice blanks, and square resin forms by side length, waste, and cost.
Resin Dice Calculator
Calculate identical cubic blanks from a side length, or use the known mixed capacity of a dice mold or set. The cube formula does not represent every polyhedral dice shape.

Match the result to the right resin class
Use the estimate to narrow the resin class first. Then confirm product limits, cure behavior, and measurement assumptions before you make a buying decision.
Measurement diagram
How much resin does a dice mold need?
A 16 mm cube contains 4.096 mL before waste. Seven identical cubic blanks need 28.672 mL raw, or 32.113 mL with the example 12% waste. For non-cubic dice or a whole polyhedral set, use the mold's known mixed capacity instead of the cube approximation.
| Cubic side | One full cube | Seven identical cubes + 12% |
|---|---|---|
| 16 mm | 4.096 mL | 32.113 mL |
| 20 mm | 8 mL | 62.72 mL |
| 25 mm | 15.625 mL | 122.5 mL |
Theoretical full cubes only, not a seven-shape polyhedral set. Use actual cavity capacity for other molds.
Cube blanks and polyhedral dice are not interchangeable
Cube mode estimates identical cubic blanks only. A 16 mm side is 1.6 cm, so one full cube contains 4.096 mL; seven identical cubes contain 28.672 mL raw or 32.113 mL with 12% waste. A d4, d8, d10, d12 or d20 mold does not have that volume merely because a listing says 16 mm. For those molds or a complete set, enter its known mixed capacity and set the count to the number of identical molds or sets.
Product data before mixing
Use the exact product documentation for mixing basis, maximum layer depth, mixed batch volume and cure or recoat conditions. A dimensional estimate and a purchase allowance do not supply those material limits.
What this calculator covers
- Cube geometry for identical cubic blanks only.
- Known mold capacity for non-cubic dice or complete sets.
- Piece or set count, small-batch mL and explicit loss allowance.
How to measure or set the inputs
- Choose inside geometry for a regular shape, or use a known cavity capacity where that mode is available.
- Set the number of identical pieces; the main quantity is the total batch, with a separate loss allowance.
- Check the raw quantity against a hand calculation or a product's published mixed capacity.
- Enter product ratio, limits and total kit mixed yield only when confirmed; purchase quantity is not a batch-mixing instruction.
Common mistakes that cost money
- Using the outside mold block instead of the dice cavity.
- Forgetting sprue and overflow material.
- Pricing dice from raw resin only and ignoring failed casts or finishing work.
Project checklist before you buy
- Confirm the mold or surface is sealed before mixing resin.
- Measure depth twice at the deepest point of the project.
- Add extra material for waste, seepage, and edge soak-in.
- Confirm the resin type matches the intended pour depth.
- Prepare cups, stir sticks, gloves, and a level work surface.
FAQ
Questions people ask before buying epoxy
Does cube mode estimate a complete polyhedral dice set?
No. It calculates identical cubic blanks. A set of different dice shapes needs a known total mixed cavity capacity; enter that as one unit and count identical sets.
How do I include sprues or a reservoir?
Include them in a known capacity if already measured, or add a clearly separate allowance. Do not count the same sprue volume twice.
