How to Measure an Oval Mold for Resin
Measure Major Diameter
Find the longest distance across your oval mold, inside edge to inside edge.
Measure Minor Diameter
Measure the shortest distance across, perpendicular to the major diameter.
Enter Depth & Calculate
Measure depth, enter all values in the calculator above, and get your resin amount instantly.
Common Oval Resin Projects
Oval Serving Trays
40 × 25 cm at 1 cm = ~785 ml. Elegant, organic shape for entertaining.
Jewelry Dishes
12 × 8 cm at 0.5 cm = ~38 ml. Mix with pastel pigments for a luxury finish.
Wall Art Panels
50 × 35 cm at 0.5 cm = ~687 ml. Ocean or geode designs for stunning pieces.
Resin Calculator for Shapes
Volume formulas and resin calculations for every common mold shape.
Circle Resin Calculator
V = π × r² × D
Enter the diameter and depth. The resin calculator multiplies π × radius² × depth to get the volume in ml. Coasters, clock faces, and round trays use this formula.
Cylinder Resin Calculator
V = π × r² × H
Enter the diameter and height of your cylindrical mold. The formula calculates the volume for pillar molds, candle molds, vases, and pen holders.
Hollow Cylinder Resin Calculator
V = π × (R² − r²) × H
Enter the outer diameter, inner diameter, and height. Calculates resin for the wall only. Perfect for bangles, rings, and tube castings.
Rectangle Resin Calculator
V = L × W × D
The simplest formula. Length × width × depth in centimeters gives you the volume in milliliters. Trays, tabletops, and mold frames are rectangular.
Square Resin Calculator
V = S² × D
Measure one side and the depth. Since all sides are equal, the formula simplifies to side² × depth. Square coasters, tiles, and trivets use this.
Oval Resin Calculator
V = π × a × b × D
An oval uses π × semi-major axis × semi-minor axis × depth. Measure the longest and shortest diameters, divide each by 2, and multiply with π and depth.
Hexagon Resin Calculator
V = (3√3 / 2) × s² × D
Measure the side length of the hexagon. The area is (3√3 / 2) × side². Multiply by depth for the volume in cubic centimeters. Hexagon coasters and tiles use this formula.
Heart Shape Resin Calculator
V ≈ known mold volume
Heart molds are irregular. Fill your mold with water, measure the water in ml, then enter that as "known volume" in the resin calculator. This gives you the exact amount of epoxy resin needed.
Oval Resin Calculator FAQ
Common questions about calculating resin for oval-shaped molds and trays.
Measure the longest diameter (major), shortest diameter (minor), and depth. Formula: V = π × (major/2) × (minor/2) × depth.
Three: the major diameter (longest distance across), minor diameter (shortest distance across), and depth (pour thickness).
40 × 25 cm at 1 cm: V = π × 20 × 12.5 × 1 ≈ 785 ml. Add 10% waste = ~864 ml.
Yes. In resin crafting, 'oval' and 'ellipse' use the same formula: V = π × a × b × D.
Measure the longest point across (major diameter) and the shortest point perpendicular to it (minor diameter). Both from inside edges.
