Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Estimated volume = bounding-box volume × shape factor. Weight = estimated volume × density; delivery loads are rounded up.
FAQ
Landscape Boulder Weight Calculator questions
What shape factor should I use?+
A lower factor represents a more rounded or irregular boulder. Compare the bounding box with the actual occupied volume.
Is the estimate safe for crane selection?+
No. Lifting equipment must use verified weights and a qualified lift plan.
Why does stone density vary?+
Rock type, mineral composition, weathering and moisture can change density.
