How Much Gravel for a 14x100 Driveway?
How much gravel for a 14x100 driveway is a quick volume problem. 1,400 square feet at 4 inches comes to 17.28 cubic yards. Gravel usually weighs about 1.3 to 1.5 tons per cubic yard, so plan on roughly 24.2 tons.
Volume and tonnage calculator →The math for a 14x100 driveway
- Area: 14 × 100 = 1,400 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 1,400 × 0.333 = 466.7 cu ft.
- Cubic yards: ÷ 27 = 17.28 yd³.
- Tons: × 1.4 = 24.2 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 8.64 | 12.1 | 13.3 |
| 3 in | 12.96 | 18.1 | 20.0 |
| 4 in | 17.28 | 24.2 | 26.6 |
| 6 in | 25.93 | 36.3 | 39.9 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
Preparing the driveway
Strip sod and soft topsoil, grade for drainage and compact the subgrade before any stone goes down. Gravel drives last longer with a compacted base layer under the top stone and a slight crown so water runs off. Since the driveway carries car and truck traffic, 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. 26.6 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 driveway 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
Poor fit 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 8x16 area at 2 inches takes about 1.1 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
