Measure the length, width and depth of each rectangular section. For irregular areas, calculate several smaller sections and add the volumes. Product densities, compaction and bag sizes vary, so verify the final order with your supplier.
How our estimates work
We multiply length × width × depth after converting all dimensions to compatible units. The result is displayed in cubic feet, cubic yards and cubic meters. The number of bags is rounded up.
What these calculators can—and cannot—tell you
These free tools calculate rectangular volumes from the dimensions you provide. They convert between cubic feet, cubic yards and cubic meters, and estimate the number of bags based on the package volume you select.
Gravel weight is only an estimate based on your chosen density. Soil settling, mulch coverage, compaction, irregular shapes and supplier packaging can change your final order. Always verify product specifications and delivery quantities before buying.
