Input dimensions

Enter surface measurements and select depth unit.

Volume Estimator

Measure the longest side of the area you need to fill.

Use the average width if your space is irregular.

Depth is often 2–3 inches for mulch, 4 inches for gravel, and 4 inches for concrete slabs.

All dimensions use the same unit. They are converted to yards internally.

Weight estimates help plan truck loads and delivery fees. Use “Volume only” when you just need cubic yards.

How to use this cubic yard calculator

Enter dimensions in a single unit (feet, inches, yards, or meters). The calculator converts each measurement to yards, multiplies them to find volume, and then gives you cubic yards alongside other useful units. Choose a material to estimate weight and hauling requirements.
