Gravel Parking Pad Calculator
Vehicle pads need more depth than a footpath and more than most people assume — an RV concentrates several tons onto four small contact patches. This calculator sizes the pad by vehicle count and type, then builds the depth to match the axle load.

Frequently asked questions
- How thick should a gravel parking pad be?
- Six inches of compacted base for cars, seven to eight for trucks and trailers, and ten or more for an RV. Depth is driven by axle load, not by pad size.
- How big is a gravel parking space?
- Nine by eighteen feet for a car and ten by twenty for a truck or SUV. An RV needs twelve by forty, and a boat on a trailer about ten by thirty.
