What Size Gravel Do I Need? (Gravel Size Chart)
The wrong gravel size can ruin a driveway or path. This gravel size chart matches each stone size to its best use, from 3/4" #57 for driveways to pea gravel for patios.
The short answer
The best gravel size depends on your project. For driveways and drainage, use #57 stone (¾"). For paths and decorative beds, pea gravel (⅛–⅜") is ideal. For a sturdy base under pavers or concrete, use #2 or #3 stone (1–2.5"). This gravel size chart matches each size to its top use.
Key takeaways
- Match gravel size to project: ¾" #57 for driveways, ⅜" pea gravel for paths.
- Proper base depth matters: 4 inches for driveways, 2–3 inches for walkways.
- Angular gravel locks together better than rounded pea gravel for stability.
- Use a gravel calculator to order the right amount and avoid extra delivery fees.
Choosing the wrong gravel size can turn a weekend driveway job into a muddy, rutted mess. The right gravel not only looks good but also drains well and stays put under car tires or foot traffic. This guide gives you a clear gravel size chart, tells you exactly which size to pick for your project, and shows you how to estimate what you need without wasting money.
What are the standard gravel sizes and their best uses?
Gravel sizes are sorted by how they pass through screen meshes. Each size has a best use based on drainage, compaction, and surface feel.
- #57 Stone (¾"): The most common driveway gravel. Drains well, compacts moderately. Also used for drainage trenches.
- Pea Gravel (⅛–⅜"): Small, rounded stones for paths, playgrounds, and decorative beds. Smooth underfoot.
- #2 Stone (2.5"): Coarse base material for heavy driveways or under concrete slabs. Provides excellent drainage.
- #3 Stone (1–2"): Often used as a base layer for construction entrances or drainage systems.
- Crusher Run (mixture): Contains stone dust and fines; packs down hard for a solid base.
- Riprap (4" and larger): Erosion control on slopes or shorelines.

How do I calculate how much gravel I need?
Getting the right amount of gravel saves you from mid-project store runs or leftover piles. You need length, width, depth, and a simple formula.
- Measure the area in feet (length × width).
- Decide the desired depth in inches. Driveways: 4 inches; walkways: 2–3 inches; decorative beds: 2 inches.
- Convert depth to feet: divide inches by 12.
- Calculate cubic feet: area × depth in feet.
- Divide by 27 to get cubic yards.
- Or use our [gravel calculator](/calculators/gravel) to do the math instantly.
How much does gravel cost?
Gravel prices vary by type, size, and location, but you can budget by the ton or cubic yard. As of June 2025, typical ranges apply.
- Pea gravel: $30 to $60 per ton or $40 to $80 per cubic yard.
- #57 Stone: $25 to $50 per ton or $35 to $65 per cubic yard.
- Crusher run: $20 to $40 per ton or $30 to $50 per cubic yard.
- Delivery fees add $50 to $150 per load depending on distance.
- Bulk orders (10+ tons) often come with a discount.
- Use our [pea gravel calculator](/calculators/pea-gravel) to compare costs for different sizes.
What are common gravel project mistakes and how much extra should I order?
Even simple gravel jobs get tripped up by wrong depth, poor base prep, or running short. Plan for waste and compaction with these tips.
- Order 10–20% extra to account for compaction and spillage. A 10x10 area at 4" needs 1.2 cubic yards, order 1.5.
- Skipping landscape fabric guarantees weeds grow through within a year.
- Using the wrong size: Pea gravel on a slope slides away; use angular crushed stone instead.
- Not compacting in lifts: compact every 2 inches for a solid driveway base.
- Ignoring drainage: slope gravel surface ¼" per foot away from buildings.
- Check our [concrete slab calculator](/calculators/concrete-slab) if you are adding a gravel base under concrete.
How do I compare gravel options for different projects?
Not all gravel is the same. Angular crushed stone locks together for stability, while rounded pea gravel shifts underfoot but feels smooth. Choose based on use, drainage, and budget.
- Crushed Stone (angular): Best for driveways and bases. Packs tight, drains well. Cost $25–$50/ton.
- Pea Gravel (rounded): Ideal for paths and patios. Looks great but can scatter. Cost $30–$60/ton.
- River Rock (large rounded): Decorative drainage areas, not for traffic. Cost $100–$200/ton.
- Crusher Run (mixed fines): Hard-packed subbase, cheapest option at $20–$40/ton.

When should I hire a pro for a gravel project?
Small paths and garden beds are DIY-friendly, but large driveways, retaining walls, or drainage systems often need a pro. Know your limits to avoid fixing mistakes.
- DIY: Any area under 200 sq ft, like a garden path or patio, with easy access for wheelbarrows.
- Call a pro when you need heavy excavation, slopes over 5%, or base depth over 6 inches.
- Retaining walls with gravel backfill require proper drainage design; if unsure, hire a contractor.
- Large dump truck access: If a truck cannot reach the site, you will spend days moving material.
- Use our [asphalt calculator](/calculators/asphalt) if you are comparing gravel vs. asphalt for a driveway.
| Best For | Pea Gravel: Paths, patios | Crushed Stone: Driveways, bases |
|---|---|---|
| Surface Feel | Smooth, shifts underfoot | Rough, locks tight |
| Drainage | Good | Excellent |
| Cost (per ton, June 2025) | $30–$60 | $25–$50 |
| Stability | Low | High |
Questions this page answers
What is the best gravel for a driveway?
#57 crushed stone, about ¾ inch, is the top choice. It compacts well for a stable surface yet drains freely, preventing puddles. Plan on a depth of at least 4 inches.
Can I use pea gravel for a driveway?
Pea gravel is smooth and rounded, so it does not lock together under car tires and easily shifts and scatters. It is better suited for walkways, patios, and garden accents. If you do use it, install a sturdy border to contain it.
How thick should a gravel layer be?
For pedestrian paths, 2-3 inches is enough. Driveways need a minimum of 4 inches, ideally placed in two 2-inch lifts compacted between layers. For a sub-base under concrete, 4-6 inches is standard.
What size gravel is used for drainage?
Clean #57 stone (3/4") or #3 stone (1-2") works well for French drains because the gaps between stones let water flow quickly. Avoid crusher run with fines, as it can clog.
How do I keep gravel from moving?
Use angular crushed stone rather than smooth pea gravel for high-traffic areas. Install edging along driveways and paths, and compact the gravel thoroughly in thin layers. A grid system or stabilizer can also lock stones in place.
What is the difference between gravel and crushed stone?
"Gravel" often refers to rounded, natural stones, while "crushed stone" is mechanically broken into angular pieces. Crushed stone locks together better, making it ideal for driveways and bases. Pea gravel is a natural, rounded gravel.
How much gravel can a pickup truck hold?
A full-size half-ton pickup can safely carry about 1 cubic yard (1.4 to 1.5 tons) of gravel. For larger orders, consider delivery by dump truck to save trips.
Do I need landscape fabric under gravel?
Yes, landscape fabric (geomembrane) is recommended under most gravel applications to prevent weeds from growing up and to stop the gravel from mixing with the soil below. It does not affect drainage if you use a permeable type.
Whether you are building a driveway or a garden path, picking the right gravel size makes all the difference. Remember: #57 stone (3/4") is the workhorse for most projects, and a depth of 4 inches keeps it solid. Always order 10-20% extra, and use our gravel calculator to nail the quantity before you buy.
