How to Measure a Square Mold for Resin
Measure the Side Length
Measure one inside edge. Since all four sides are equal, you only need one measurement.
Measure the Depth
Measure from the bottom to the desired fill level. Coasters: 0.5–1 cm. Paperweights: 2–3 cm.
Enter & Calculate
Enter the side length and depth above, choose your ratio. V = S² × D gives your total volume.
Common Square Resin Projects
Square Coasters
10 cm at 0.5 cm = 50 ml each. Sets of 4 or 6 are popular gifts.
Decorative Tiles
15 cm at 0.3 cm = 67.5 ml each. Mix different colors for a mosaic effect.
Trivets
20 cm at 1 cm = 400 ml. Use heat-resistant epoxy for hot dish trivets.
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.
Square Resin Calculator FAQ
Common questions about calculating resin for square molds and tiles.
Measure the side length and depth. The formula is V = side² × depth. A 10 × 10 × 1 cm square mold needs 100 ml.
A square is a rectangle where length equals width. You only need to measure one side instead of two.
10 cm square at 0.5 cm = 50 ml each. Set of 4: prepare 220 ml (200 ml + 10% waste).
Yes. Measure the side length and thickness, enter them in the calculator for exact resin amounts per tile.
10 cm coasters, 15 cm trivets, 20 cm wall art, 30 cm serving boards. Depth: 0.3–2 cm.
Level your workspace with a spirit level before pouring. Pour slowly and let the resin self-level.
