Gravel Calculator
Estimate how many tons of gravel you need for an area.
Estimating gravel for a driveway, path, or drainage project means converting an area and depth into tons — this calculates that from your project's dimensions.
Why gravel is sold by weight, not volume
Gravel suppliers typically sell by the ton rather than by volume, since gravel density varies by material type — this calculator uses a standard density assumption, but ask your specific supplier for their material's exact density for the most accurate order.
Frequently asked questions
How deep should a gravel driveway layer be?
A typical gravel driveway uses 4-6 inches of depth, sometimes in multiple compacted layers — check local guidance for your specific application and soil conditions.
Should I order extra gravel beyond the calculated amount?
A 5-10% buffer is common practice to account for settling, compaction, and measurement variance.
