Gravel types for driveways and paths: #57, crusher run, pea gravel and more

Clean stone vs stone with fines

The most useful distinction isn’t size — it is whether the stone is clean (washed, one size range, with gaps between the stones) or dense-graded (a mix of sizes down to dust, called fines).

• Clean stone drains freely and doesn’t compact much. Good for drainage, as a middle layer, and under decks. It can shift under tires on its own.
• Dense-graded stone packs into a hard, stable layer when compacted, because the fines fill the gaps. That makes it the usual base under driveways, patios and sheds. It drains more slowly than clean stone.

Most good driveways use both: a compacted dense-graded base and a clean or semi-clean top layer.

The common types

For a driveway

A typical built-up gravel driveway has two or three layers:

1. Base: crusher run or larger clean stone (#3, roughly 1–2 in), compacted — commonly 6–8 in on firm, well-drained soil and more on clay or soft ground, where a woven geotextile underneath also helps keep the stone from sinking into the mud. Local soils and practice vary, so ask a local contractor or the quarry what holds up where you live.
2. Middle (optional): 3–4 in of #57 for drainage.
3. Top: 2–3 in of #411 — #57 with its stone dust mixed back in — is a common choice, because the dust binds the stones into a firm surface that tires don’t push around. Crusher run packs firm too but can get dusty or muddy; clean #57 on top drains well but rolls and scatters under tires. Not every region uses the #411 name, so ask for “#57 with fines” or the yard’s driveway topping.

Pea gravel is a poor driveway surface: round stones roll under tires, rut easily and migrate into the lawn. River rock is worse. Both are fine for walkways and patios where nothing heavy drives on them.

In numbers: a new 12 × 50 ft single-car driveway with a 6 in crusher-run base and a 3 in #411 top runs to roughly 32 tons of stone once compaction is counted — see How much gravel for a 12×50 driveway for the layer-by-layer breakdown. Freshening an existing surface is a much smaller order; How much gravel to resurface a 12×60 driveway works through a 2 in top-up of #411.

For a garden path

Paths carry feet and wheelbarrows, not cars, so a thinner build works. A common approach is 2–3 in of compacted crusher run or stone dust, topped with 1–2 in of pea gravel, fine crushed stone or DG. Pea gravel alone, deep, is tiring to walk on — like walking on marbles. A firm base under a thin decorative layer solves that. For a simple 3 in pea gravel path over fabric, How much pea gravel for a 3×30 ft garden path shows the tonnage, the bag count and the edging.

Edging matters more than stone choice on a path. Steel, aluminum, stone or brick edging set slightly above the gravel keeps it from spreading into beds and lawn. Remember a path needs edging on both sides — the landscape edging calculator handles that.

Around the house and in beds

Decorative rock along foundations stops splashback, doesn’t hold moisture against the siding the way mulch can, and never needs replacing. Use river rock or a decorative crushed stone over landscape fabric, deep enough to hide it: a common rule of thumb is about twice the stone size for small stone (under about 1½ in), and one stone deep plus about an inch for larger rock, so 3–5 in stone ends up about 4–5 in deep. Keep the finished grade sloping away from the house.

For drainage

Anything that has to move water — a French drain, a drainage strip along a wall, the backfill behind a retaining wall — wants clean stone such as #57, with no fines to clog the gaps. Wrap it in filter fabric so the surrounding soil can’t wash in and silt it up; that fabric wrap is what keeps a drain working for years. The French drain calculator works out the stone, the pipe and how wide a strip of fabric to buy for your trench.

For a shed base

A gravel shed pad is a small job with one rule people miss: make the pad about a foot wider than the shed on every side, so rain dripping off the roof lands on stone rather than soil, and the frame never sits on the pad’s crumbling edge. Use angular crushed stone — #57 or crusher run — compacted in 2–3 in layers; pea gravel rolls under the skids. How much gravel for a 10×12 shed base works through the 12 × 14 ft pad a 10 × 12 shed needs, and How much gravel for a 12×16 shed base the next size up.

Buying stone: tons, yards and loads

Quarries mostly sell by the ton; some landscape yards sell by the cubic yard. To convert, you need the material’s density. For common gravels it is about 1.4 tons per loose cubic yard — so a ton is roughly 0.7 yards, which covers about 73 sq ft of #57 at 3 in deep once it has settled.

loose cubic yards = length (ft) × width (ft) × compacted depth (in) ÷ 12 ÷ 27 × compaction factor
tons = loose cubic yards × loose density (tons per cu yd)

• Ask the supplier for their conversion. Moisture, stone type and grading shift it.
• Dense-graded base (crusher run, DGA) loses 20–30% of its loose volume when compacted — order about 1.25× the compacted volume (≈1.9 tons per compacted cubic yard). Clean stone compacts only 5–10%.
• Ask how many tons a truck carries and whether there is a short-load fee for small orders.
• Check where the truck can dump without damaging the driveway or lawn edges; loaded trucks are heavy.

Fabric or no fabric?

Under driveways on soft soils, a woven geotextile helps separate the stone from the soil so the base doesn’t pump into the mud. Under paths and decorative rock, a non-woven or woven landscape fabric helps keep stone from sinking. What fabric won’t do is stop weeds long-term: dust and seeds collect in the gravel on top, and weeds root there. Expect some maintenance either way. Fabric comes in fixed roll widths and each seam needs an overlap, so you buy more than the bare area — the landscape fabric calculator lays out the strips.
