How to Use This Calculator

Enter finished dimensions (height, width, depth in inches).
Select stone type (marble, limestone, granite, soapstone, alabaster) for density and carving factors.
Set clearance per side (in) -- the extra material needed around the finished form.
Review block weight in lbs and kg, block dimensions, and estimated material cost.
Purchase 30-50% more stone by weight than the finished piece -- carving removes significant material.
