How much gravel for a 100 ft driveway?
A 10 × 100 ft gravel driveway built in three layers needs about 62.4 tons of stone: 36.5 tons of crusher run for a 6 inch compacted base, 14.3 tons of #57 for a 3 inch drainage layer and 11.7 tons of #411 for a 2 inch top, with compaction and 5% waste.
How to work it out
- 100 ft × 10 ft = 1,000 sq ft
- Base: 1,000 sq ft × 6 in = 18.5 cu yd compacted × 1.25 = 23.1 cu yd loose × 1.5 tons/cu yd = 34.7 tons
- + 5% waste = 36.5 tons
- Effective rate: ≈ 1.97 tons per cu yd compacted
- Base order: 36.5 tons rounded up to the next ½ ton = 36.5 tons
- Middle: 1,000 sq ft × 3 in = 9.26 cu yd compacted × 1.05 = 9.72 cu yd loose × 1.4 tons/cu yd = 13.6 tons
- + 5% waste = 14.3 tons
- Effective rate: ≈ 1.54 tons per cu yd compacted
- Middle order: 14.3 tons rounded up to the next ½ ton = 14.5 tons
- Top: 1,000 sq ft × 2 in = 6.17 cu yd compacted × 1.2 = 7.41 cu yd loose × 1.5 tons/cu yd = 11.1 tons
- + 5% waste = 11.7 tons
- Effective rate: ≈ 1.89 tons per cu yd compacted
- Top order: 11.7 tons rounded up to the next ½ ton = 12 tons
- Total: 62.4 tons
Longer rural drives often cross softer ground and see farm, fuel or delivery trucks, which is why this example uses a 6 in base plus a 3 in layer of clean #57 for drainage before the #411 top. Around 62 tons is several truckloads; talk to the quarry about spreading as they dump (a "tailgate spread") to save hours of raking. For a shorter drive, compare how much gravel for a 12×50 driveway.

What to know about a 100 ft gravel driveway
At this length the job is logistics. A single-axle dump truck often carries somewhere around 6–8 tons, so the base alone is several loads; a tri-axle carries more but needs firm ground to turn around on. Ask the supplier what their trucks carry and set the truck size under More options to see how many deliveries to book.
Ten feet is narrow for a hundred-foot run. If the drive curves, widen the bends to 12–14 ft so long vehicles don’t cut the corners into the lawn, and add the extra area under More options.
The #57 middle layer is there for water. Clean stone has open gaps, so water that gets through the top drains sideways instead of softening the base. It only helps if that water has somewhere to go: crown the drive, cut shallow ditches or turnouts where it runs downhill, and put a culvert where it crosses a low spot rather than piling more stone in the dip.
A deeper base costs more stone up front but it is the layer you never have to redo. If your drive is sound and only the surface has worn, how much gravel to resurface a 12×60 driveway shows the much smaller top-up.

Frequently asked questions
How much gravel for a 100 ft driveway with an 8 inch base?
About 74.6 tons: 48.6 tons of crusher-run base, 14.3 tons of #57 and 11.7 tons of #411 on top, 10 ft wide, with compaction and 5% waste.
How much gravel for a 100 ft driveway without the #57 layer?
About 48.1 tons with a 6 in base (36.5 tons) and 2 in of #411 (11.7 tons). Fine on well-drained ground; on wet ground the drainage layer earns its keep.
How much gravel for a 12×100 driveway?
About 74.9 tons with the same three layers: 43.8 tons of base, 17.2 tons of #57 and 14 tons of top stone.
