Sculpture Calculators
Calculators for clay weight, armature sizing, mould volumes, plaster mixing and casting materials.
Clay Weight Calculator
Estimate clay weight for solid or hollow sculptures. Covers earthenware, stoneware, porcelain and air-dry clay with shrinkage.
Armature Calculator
Calculate wire and rod lengths needed for sculpture armatures based on figure height, pose type and proportions. Free calculator.
Mould Volume Calculator
Calculate the volume of silicone, plaster, alginate or jesmonite needed to make a sculpture mould. Includes weight and cost estimates.
Plaster Mix Calculator
Work out the correct plaster-to-water ratio by weight for casting and mould making. Covers Plaster of Paris, Herculite and more.
Bronze Weight Calculator
Estimate bronze casting weight and material cost from wax model dimensions. Essential for planning lost-wax bronze sculpture.
Casting Calculator
Calculate resin, plaster, concrete or jesmonite volume and weight for sculpture casting. Includes waste allowance and cost estimate.
Sculpture Wire Calculator
Calculate wire length and gauge needed for wire sculpture based on design height and complexity. Covers aluminium, steel and copper wire.
Patina Calculator
Calculate chemical patina solution quantities for bronze and metal sculpture finishing. Covers liver of sulphur and ferric nitrate.

Sculpture Materials & Calculations
Sculpture involves working with heavy, often expensive materials where getting quantities wrong is costly. Estimating clay weight, plaster ratios and casting volumes before you start ensures you have enough material and stay within budget.
The clay weight calculator estimates the amount of clay needed for solid or hollow sculptures based on dimensions and clay type. Our plaster mix calculator provides the correct plaster-to-water ratio by weight, which is critical for achieving the right strength and setting time.
For casting work, the mould volume calculator determines how much silicone or plaster you need for a mould, while the bronze weight calculator estimates the weight and cost of a bronze casting from your wax model dimensions.
