Use the Gravel CalculatorDriveway gravel settles: plan for loose depth, calculate for compacted depth
Gravel is delivered loose and settles (compacts) when rolled or driven on. The calculator uses compacted depth—the finished thickness after settling—because that is what determines how much material you actually need to order.
A driveway finished at 2 inches of compacted gravel requires more loose gravel to account for settling. The exact ratio depends on stone size and compaction method (hand-raked, lightly rolled, or heavily compacted).
Measure driveway length, width, and intended compacted depth
Measure the length of the entire driveway from road to garage or turnaround. Measure the width from edge to edge (or inside the ruts if it is already partially graveled). Record the depth in inches—typically 2 to 3 inches for a finished surface, 4 inches for a new base layer.
If the driveway varies in width or slope, break it into sections (straight sections vs. apron vs. turnaround) and measure each one separately.
Multi-section drives: apron, straight run, and turnaround
A typical residential driveway has three sections: the apron (at the road), the straight run (the main length), and the turnaround or parking area. Each may have a different width or depth.
The apron is often wider (to meet road width) and may need deeper gravel for better drainage. The turnaround is wider than the run to allow vehicle turning. Measure and calculate each section, then add the volumes.
Slope and drainage affect the actual depth you order
A driveway sloped for drainage uses more gravel at the low edge than at the high edge if you want a consistent finished height. If you are starting from bare soil, the slope does not matter much—the gravel naturally settles into a drained contour.
If you are filling an existing rut or eroded area, the depth varies across the width. Use the deepest required depth to ensure full coverage, knowing you will have extra in the shallow areas.
Field measurement worksheet
Walk the entire driveway with a tape measure. Record each section below. Note any steep slopes or wet spots that may affect gravel depth.
| Section | Length (ft) | Width (ft) | Depth (in) | Volume (cu ft) |
|---|---|---|---|---|
| Apron (road to first 10 ft) | ||||
| Straight run (main driveway) | ||||
| Turnaround or parking | ||||
| Total |
Volume per row = length × width × (depth ÷ 12). Add all rows. Convert to cubic yards by dividing by 27. Add 10–15% for settling and uneven base.
Worked example: 50-foot driveway
A driveway is 50 feet long, 10 feet wide, with a 2-inch finished (compacted) depth. It is one straight section with no turnaround.
Volume: 50 × 10 × (2 ÷ 12) = 83.3 cubic feet = 3.08 cubic yards.
Add 15% for settling and base unevenness: 3.08 × 1.15 = 3.54 cubic yards. Order 3.5 or 4 cubic yards depending on supplier minimum and increment.
Pre-order checklist
Before ordering, confirm the stone size (crushed stone, marble chips, recycled asphalt, etc.), finish compaction method, and any delivery fees.
- Driveway sections measured and recorded (apron, straight, turnaround).
- Total length, width, and depth for each section in feet and inches.
- Compacted depth, not loose depth (the finished thickness you want to see).
- Total volume in cubic yards with a 10–15% settling allowance included.
- Stone type and size (crushed stone, pea gravel, recycled asphalt, etc.).
- Supplier contact and quote for the material and delivery fee.
- Truck access confirmed: width of gate, weight limit, and driveway base condition.
- Method of compaction (hand rake, light roll, or heavy compaction) that affects settling estimate.
