How to Calculate Gravel for Your Project
04/06/2026
Gravel is usually sold by weight or bag size, but the project itself is measured by area and depth. That is why the most reliable starting point is to calculate volume rather than guessing how many bags will be needed.
Measure the length and width of the area, decide the finished depth, then convert all measurements to metres.
Depth should match the application.
