Pea Gravel Calculator

How to calculate

Use the average layer depth over the measured footprint. Bags are an alternative purchase method to bulk yardage, not an additional order.

Worked example

Length (ft): 16 · Width (ft): 12 · Material depth (in): 2 · Bag yield (cu ft): 0.5 · Extra material (%): 10.

These inputs produce 1.3 cubic yards to order. Change the measurements above to match your project.

Before you order

Check bag volume rather than assuming all bags with the same weight have the same yield. Account for existing material you plan to keep.

For an irregular footprint, split the project into rectangles. Calculate each section and combine unrounded quantities before rounding the final order. Ask the supplier to confirm product yield and available package sizes.
