Estimate gravel volume, cubic yards, cubic feet, tons, and bag counts for driveways, walkways, drainage trenches, patios, and landscaping projects.
Volume formula:
Length × width × depth = total gravel volume
Weight formula:
Volume × density = total gravel weight
This calculator estimates gravel volume, cubic yards, cubic feet, tons, and approximate bag count.
Knowing how much gravel you need helps when planning driveways, paths, drainage areas, and landscape projects so you can order enough material without overspending.
Accurate gravel depth helps with drainage, stability, and finished appearance.
Your result shows the estimated gravel volume based on the area dimensions, depth, and density entered. It also includes cubic yards, total weight, and an approximate number of bags based on the bag size selected.
Actual needs can vary depending on compaction, settling, and gravel shape. For larger projects, ordering bulk gravel by the yard or ton is usually more practical than bags.
Multiply the area length by width and depth to find total volume, then apply density to estimate the total weight.
Both are common. Suppliers often sell gravel by the ton or cubic yard, so it helps to know both measurements.
Many decorative areas use 2 to 3 inches, while driveways and base layers often need more depth depending on the project.
Small projects are often easier with bags, while larger projects are usually more cost-effective with bulk gravel.
