How to Use This Calculator

Enter the sculpture's bounding box dimensions: height, width, and depth in inches.
Select clay type (water-based, oil-based/plasteline, polymer, or air-dry).
Set construction method (solid, hollow, or armature-supported) to adjust fill factor.
Review clay weight in lbs and kg, clay volume in cubic inches, and number of 25-lb bags.
Order 10-15% extra clay to account for waste, armature voids, and surface reworking.
