Quick answer:a good gravel driveway is a layered system. Compact crushed stone with fines (#411 or item 4) for the base, then top with angular crushed stone (#57 or #67) for the visible surface. Decorative gravels — pea gravel, river rock, decomposed granite — can be the top course, but only over a compacted base. Skipping the base layer is the single most common reason driveways rut, pothole, and need redoing within a season.
Below are the six types you will encounter at most U.S. supply yards, with the trade-offs that decide which one belongs on your project. Use the Gravel Calculator to size each layer in tons and cubic yards before calling the supplier so you can order both the base and top course on one delivery.
Quick comparison
| Gravel | Size | Best for | Weakness |
|---|---|---|---|
| Crushed stone #411 / item 4 | Up to 1.5″ + fines | Base layer, compacts hard | Muddy if exposed |
| Crushed stone #57 | ~3/4″ | Top course, drains well | Loose to walk on |
| Crushed stone #67 | ~1/2–3/4″ | Top course, foot-friendly | Drains slightly slower than #57 |
| Pea gravel | ~3/8″ | Decorative surface course | Migrates, needs edging + base |
| River rock | 1–3″ rounded | Decorative drainage areas | Hard to walk on, not for driveways |
| Decomposed granite | Stone dust + chips | Stabilized surface course | Dust, needs binder for vehicle use |
1. Crushed stone #411 (item 4 / ABC)
#411 is the structural base under most residential driveways. It is a mix of crushed stone up to about 1.5 inches plus stone dust (“fines”). The fines lock the larger stones together when the layer is compacted, which is what gives the driveway its load-bearing strength. Regional supply yards sell the same product under different names: item 4 in the Northeast, ABC (aggregate base course) in the Mid-Atlantic, road base or class 5 in the Midwest and West, and crusher run in some areas.
Use 4 to 6 inches of compacted #411 as your base layer, installed in 2 to 3 inch lifts with a plate compactor between lifts. Then finish with a separate top course. Do not leave #411 as the visible surface — the fines turn to slurry in heavy rain.
2. Crushed stone #57
#57 is the most common driveway top course in the United States. It is angular crushed stone sized about 3/4 inch, with the angular faces giving it the interlocking behavior that keeps the surface from rolling under tires. #57 drains well, resists plowing damage, and is widely available because it is also the standard concrete aggregate and a primary French drain rock.
Two to three inches of #57 over a compacted #411 base is a durable residential driveway top. If you also need rock for a French drain on the same job, this size doubles up cleanly so you can order everything in one delivery.
3. Crushed stone #67
#67 is similar to #57 but slightly smaller and more tightly graded (roughly 1/2 to 3/4 inch). The smaller, more uniform stones sit flatter, which makes the driveway noticeably easier to walk on without sacrificing much drainage. Choose #67 over #57 if the driveway sees regular foot traffic from the house to the car, or if you want a slightly more finished look. Drainage is a hair slower than #57 but rarely a deciding factor in residential use.
4. Pea gravel
Pea gravel is small rounded stone about 3/8 inch in diameter, named for its size and shape. It is the most popular decorative driveway surface because of the warm color range — tan, brown, slate, mixed — and the smooth, casual look. The trade-off is real: rounded stones do not interlock, so pea gravel migrates under tires and feet. Treat it as a top course only, installed at most 2 inches deep over a compacted #411 base, with a steel, stone, or timber edging restraint around the perimeter.
Plan to rake and top up once a year. If you cannot live with that maintenance pattern, choose #57 or #67 for the surface instead.
5. River rock
River rock is rounded stone in the 1 to 3 inch range, smoothed by water. It is a poor driveway surface because the rounded shape and larger size make it hard to walk on, slippery underfoot, and impossible to plow. Use river rock instead in drainage swales, dry creek beds, and decorative borders next to a driveway, where its appearance carries weight without daily traffic.
6. Decomposed granite
Decomposed granite (DG) is weathered granite that has broken down into a mix of stone dust and small chips. As-is, it compacts to a firm, somewhat dusty surface that is common on garden paths and xeric landscapes in the Southwest. For vehicle driveways, ask for “stabilized DG” or plan to apply a stabilizing binder — otherwise the surface dusts heavily in dry climates and ruts in wet ones. DG is most popular in California, Arizona, New Mexico, Nevada, and Texas, where its color matches local soils and the dry climate suits it.
How much gravel do I need?
A standard residential driveway is around 12 ft wide. For a 30 ft long driveway with a 4 inch base and 2 inch top course, that works out to:
- Base (#411):30 × 12 × (4/12) ÷ 27 = ~4.4 cubic yards (~6 tons at 1.4 t/yd³)
- Top course (#57 or #67):30 × 12 × (2/12) ÷ 27 = ~2.2 cubic yards (~3 tons)
Add 5 to 10 percent for compaction and waste, especially on the base layer where you will lose volume when the plate compactor tightens up the material. The Gravel Calculator handles the math, including density by gravel type and the right waste factor for each layer.
Cost expectations
Bulk gravel is cheap; delivery is what drives the bill. Crushed stone in most U.S. markets runs roughly $20 to $40 per ton picked up at the yard, or $40 to $80 per ton delivered for short hauls. Decorative gravels like pea gravel, river rock, and decomposed granite are 1.5 to 3x the price of plain crushed stone. The right way to control cost is to size your order accurately so you only pay one delivery fee, not two.

Frequently asked questions
What is the best gravel for a driveway?
A two-layer system: crushed stone #411 (or item 4) for the base, then crushed stone #57 or #67 for the top course. Decorative gravels work as a surface only over a compacted base.
What size gravel is best for a driveway?
Most residential driveways use 3/4 inch crushed stone (#57) for the top and 1.5 to 2 inch crushed stone with fines (#411) for the base. The base size locks together when compacted; the top size drains and resists ruts.
Is pea gravel good for a driveway?
Pea gravel is decorative, not structural. Use it only as a contained surface course over a compacted #411 base, with edging. For a low-maintenance driveway, choose #57 or #67 instead.
How much gravel do I need for a driveway?
A typical 30 ft by 12 ft driveway needs about 6 tons of base (#411) and 3 tons of top course (#57). The Gravel Calculator handles both layers separately.
How long does a gravel driveway last?
10 years or more with light maintenance: annual grading, topping up the surface course every 2 to 3 years, and keeping the perimeter contained. Failure usually traces to a missing or thin base.
