Epoxy Resin Volume Calculator
How to use the epoxy calculator
Enter the length, the width and the depth of your project in inches. The calculator gives the amount of mixed epoxy (resin and hardener together), suggests a resin for that depth and shows the kits that give you that amount.
How to measure
- Length and width: measure the surface, or the inside of the mold, in inches.
- Depth: the thickness of the resin. A self-leveling flood coat is about 1/8 inch.
- River table: measure only the space that the resin fills, the channel between the wood slabs. Use the average width of the channel.
- Round surface: enter the diameter as the length and as the width. The result is then more than you need, because a circle is smaller than a square of the same width.
How much extra to mix
The calculator adds 5% to the volume for normal losses, for example the resin that stays in the mixing cup and on the tools. The result shows US units (ounces or gallons) and metric units (milliliters or liters).
Table top, deep pour or art & craft resin
Choose the resin by the depth of each pour.
- Table Top & Coating Resin: pours of up to 1/4 inch at a time, for coatings on table tops, bar tops, countertops and art.
- Deep Pour, Casting & Art Resin: pours of up to 2 inches or up to 4 inches at a time, for river tables, casting and embedding.
- Art & Craft Resin: pours of up to 3/4 inch at a time, for jewelry, coasters, molds and other craft projects.
Frequently asked questions
Does the result include the hardener?
Yes. The result is the total volume of mixed epoxy: resin (A) and hardener (B) together. Our kit sizes are also resin and hardener together. For example, the 32 oz Table Top kit has 16 oz of resin and 16 oz of hardener.
Can I pour the full depth at once?
Only if the depth is not more than the limit of the resin: 1/4 inch per pour for the Table Top & Coating Resin, 3/4 inch per pour for the Art & Craft Resin, and 2 or 4 inches per pour for the Deep Pour resin (by formula). For a deeper project, pour in layers.
Which resin is right for a river table?
Use our Deep Pour, Casting & Art Resin. If each pour is 2 inches deep or less, the 2-inch formula works and cures faster. For pours from 2 to 4 inches, use the 4-inch formula. See our river table guide.
