How Much Gravel for a 24x36 Parking Pad?
How much gravel for a 24x36 parking pad is a quick volume problem. 864 square feet at 4 inches comes to 10.67 cubic yards. Gravel usually weighs about 1.3 to 1.5 tons per cubic yard, so plan on roughly 14.9 tons.
Volume and tonnage calculator →The math for a 24x36 parking pad
- Area: 24 × 36 = 864 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 864 × 0.333 = 288.0 cu ft.
- Cubic yards: ÷ 27 = 10.67 yd³.
- Tons: × 1.4 = 14.9 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 5.33 | 7.5 | 8.2 |
| 3 in | 8.00 | 11.2 | 12.3 |
| 4 in | 10.67 | 14.9 | 16.4 |
| 6 in | 16.00 | 22.4 | 24.6 |
About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
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. For parked vehicles, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 16.4 tons may take more than one 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.
Where gravel fits
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 12x24 area at 2 inches takes about 2.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
