Shed Gravel Pad Calculator

Estimate a gravel pad footprint, material volume, approximate tonnage, and cost from your shed size and your supplier’s pricing.

How the gravel estimate works

Add the pad extension to each side of the shed, calculate the area, and multiply by depth in feet. Add the material allowance, divide cubic feet by 27, and multiply cubic yards by the editable density to estimate tons.

Gravel density, compaction, drainage, site conditions, and foundation requirements vary. This is a material-planning estimate—not engineering approval or a construction specification.

Check local building requirements and the shed manufacturer’s instructions. Read the shed gravel pad planning guide.
