Gravel Driveway Planner

Plan different depth zones and gravel layers, then estimate cubic yards, short tons, delivery loads, and cost.

Enter your project

Change the starting values to match your site and the product you plan to buy.

Changing units converts your entered measurements.

1. Draw and measure your plan

Use a rectangle, triangle, circle, or custom polygon for each measured section. For a polygon, enter its corners in order or drag the numbered handles in the drawing. Move a whole section by dragging its fill. Excluded areas must stay within the included plan, and overlaps must be fixed before calculating.

2. Set the first gravel layer

Add another row for each different material; adjust depth by section above.

3. Add another gravel layer

Use a separate row for a different aggregate, density, or price. To change a layer depth in one section, open the depth controls for that section above.

Use the same measurements in another planner

Save a named project above, then choose it here or open it in another planner. Only the measured areas and display units carry over. Check the new tool’s product, depth, waste, and price settings before ordering.

The measured 2D footprint is scaled; the layer or product view explains quantities separately.

Swipe the diagram sideways to see every label. The calculated quantities are listed below.

Your estimate appears here

Enter the measurements and select Calculate. You will see quantities, assumptions, and a shopping list.

Compare two options

Calculate with one set of inputs, save it as A, then change the design or supplier values and save B. Both options stay on this device.

How this calculation works

YardSetup keeps the measured amount separate from the quantity you may need to purchase. Enter product dimensions and supplier figures where they differ from the starting values.

For each material layer, add each section’s net area × its finished depth ÷ 324 to get finished cubic yards. Apply that layer’s allowances, then multiply order yards by its supplier density for short tons.

A quick example

A 600 sq ft driveway at 3 inches has 5.56 finished cubic yards before allowances; the weight depends on the actual gravel density.

This is a planning estimate. Review the inputs and confirm material specifications, local conditions, and delivery units before ordering.

✓ Plan with confidence

Ask the supplier for each product’s density.

✓ Plan with confidence

Override a layer’s depth inside a measured section when it differs; use 0 if absent.

✓ Plan with confidence

Confirm truck capacity and unloading access before relying on a load count.
