Building Materials Calculator
Calculate exact block counts for solid boxes, hollow shells, walls, floors, outlines, pyramids and real voxel spheres, converted straight to stacks and shulkers.
All figures here are estimates built from the documented vanilla formulas — useful for planning, not a substitute for in-game testing. Values can shift slightly between Minecraft versions.
