Which calculator do I need?
- Use the concrete calculator for anything you pour: slabs, footings, walls, steps cut into rectangles, and round post holes or columns.
- Use the gravel calculator for anything you spread: driveway gravel, base under pavers, sand and topsoil. For garden beds, the mulch calculator compares bags with bulk.
- Building something? The paver, concrete block, fence and deck calculators turn your measurements into a parts list.
