How Much Gravel for a 24x30 Parking Pad?
A 24 by 30 foot parking pad is 720 square feet. How much gravel for a 24x30 parking pad depends on depth: at 4 inches it is about 8.89 cubic yards or 12.4 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 24x30 parking pad
- Area: 24 × 30 = 720 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 720 × 0.333 = 240.0 cu ft.
- Cubic yards: ÷ 27 = 8.89 yd³.
- Tons: × 1.4 = 12.4 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 4.44 | 6.2 | 6.8 |
| 3 in | 6.67 | 9.3 | 10.3 |
| 4 in | 8.89 | 12.4 | 13.7 |
| 6 in | 13.33 | 18.7 | 20.5 |
About gravel
Because ’gravel’ covers so many products, the weight per yard moves with stone size and how much fine material is in the pile. Rounded stone with no fines rolls under tires; crushed stone with fines locks together. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
Preparing the parking pad
Dig out organic soil, compact the subgrade and set an edge so the stone does not migrate onto the lawn. A pad that holds parked weight for long periods benefits from a dense base under the surface stone. Since the parking pad carries parked vehicles, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 13.7 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the parking pad as firm ground allows.
When to choose gravel
Good uses:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Think twice for:
- Steep slopes, where loose stone washes downhill
- Spots plowed often, since plows push gravel into the lawn
- Areas next to doors, because stone tracks inside
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 20x25 area at 2 inches takes about 4.3 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
