Gravel direct answer
How much gravel for a 10x10 driveway?
A 10 ft by 10 ft driveway area with 4 inches of gravel needs 1.24 cubic yards, or about 1.73 tons, before waste. With 10% overage, order about 1.4 cubic yards or roughly 2.0 tons of gravel.
Quick answer
| Area | 100 sq ft |
|---|---|
| Depth assumption | 4 inches |
| Base volume | 33.33 ft3 / 1.24 yd3 |
| Estimated weight | 1.73 tons before waste |
| Order with 10% waste | 1.4 yd3 / about 2.0 tons |
Calculation steps
- Convert 4 inches to feet: 4 / 12 = 0.333 ft.
- Multiply length x width x depth: 10 x 10 x 0.333 = 33.33 cubic feet.
- Convert cubic feet to cubic yards: 33.33 / 27 = 1.24 cubic yards.
- Estimate tons using 1.4 tons per cubic yard: 1.24 x 1.4 = 1.73 tons.
- Add 10% for waste, spreading variation, and compaction: order about 1.4 cubic yards or 2 tons.
How to decide what to buy
Use depth as the real decision
Four inches is a planning depth for a light gravel parking pad or driveway refresh. A new driveway over weak soil may need a thicker base built in lifts, and a decorative top layer should not be counted as structural base.
Order by tons when the yard sells by weight
Landscape yards often quote gravel by the ton, while calculators work in cubic yards. Density changes by stone type and moisture, so the ton number is an estimate until the supplier confirms the product.
Plan compaction separately
Loose gravel settles after spreading and compaction. If the finished grade must meet a garage apron or sidewalk, measure from the compacted target height, not the loose pile height.
Project-specific notes
For a 10x10 gravel driveway pad, the calculation assumes the entire 100 sq ft area gets the same 4 inch compacted depth. That is a good quick answer for a small parking pad, shed access strip, trash can pull-off, or a short extension beside an existing driveway. It is not the same as rebuilding a failed driveway over clay, topsoil, or standing water.
If the area will carry daily vehicle traffic, think in layers. A common small-driveway plan may use a thicker compacted base stone layer and a thinner top-dress layer. The 1.4 yd3 order number should be treated as one 4 inch layer, not as a complete engineered driveway section.
Access also changes the order. If the dump truck can tailgate spread the stone, waste is lower. If the pile lands in the street and gets moved by wheelbarrow, allow more loss at edges and more time for leveling.
Buying checklist
- Confirm whether the supplier sells the selected gravel by cubic yard, ton, or minimum delivery load.
- Ask for the product density or a tons-per-yard conversion for the exact stone size.
- Measure the compacted finished grade against nearby concrete, garage aprons, or sidewalks.
- Plan landscape fabric and edge restraint before the gravel is delivered.
Recalculate if
- The gravel depth is 6 inches instead of 4 inches.
- The existing base is soft, muddy, or full of organic soil.
- The driveway area is wider than the visible tire path.
- You are ordering separate base rock and decorative top stone.
Common mistakes
- Using a 2 inch decorative depth when the surface will carry vehicles.
- Forgetting fabric, edge restraint, or base repair when existing soil is soft.
- Ordering exactly 1.24 cubic yards and then running short after spreading and compaction.
