How to Build a Gravel Driveway (Base, Depth & Layers)
Part of Landscaping & Aggregate
Quick answer
Build a gravel driveway in layers totaling 4–6 inches (8–12 inches for heavy trucks): a coarse compacted base of crusher run, an optional middle layer, and a finer #57 or #411 surface. Compact each layer, and use landscape fabric over soft soil.
A durable gravel driveway isn't one dump of stone — it's layers that each do a job: a strong base that spreads weight, and a finer top that's comfortable to drive on. Depth is about load and drainage.
How deep should a gravel driveway be?
| Use | Total depth | Layers |
|---|---|---|
| Light use / parking pad | 4 in | 1–2 layers |
| Residential cars | 4–6 in | 2 layers |
| Frequent / heavy trucks | 8–12 in | 3 layers |
| Soft or clay soil | +2–4 in base | add fabric |
The layers, bottom to top
- Fabric: lay geotextile over graded soil so stone can't sink and weeds can't grow.
- Base: 3–4 in of crusher run or #2 stone, compacted.
- Middle (optional): 2–3 in of #57 to lock the base.
- Top: 2–3 in of #411 or #57 for the driving surface; crown the center so water sheds.
- Compact each layer with a plate compactor or roller before adding the next.
Multiply length × width × total depth to get the volume, then order by the ton — the gravel calculator converts cubic yards to tons for you.

How many inches of gravel for a driveway?
4–6 inches total for residential use, built in layers, and 8–12 inches where heavy trucks drive or the soil is soft.
