Gravel Types by Use
#57 Stone — Best base layer for driveways. Angular, compacts well.
Crusher Run (#21A) — Mix of stone and fines. Packs solid, great driveway top layer.
Pea Gravel — Round and smooth. Good for paths and decorative beds, not driveways.
River Rock — Decorative landscaping and drainage applications only.
Decomposed Granite — Compact walkways, paths, and xeriscaping beds.
3-Layer Driveway System

A properly built gravel driveway uses three compacted layers:

Bottom (4") — 3-inch diameter base stone (#3 stone). Creates a stable foundation.
Middle (4") — #57 crushed stone. Bridges gap between base and surface.
Top (2–3") — Crusher run or #21A. Compacts into a firm, drivable surface.
Tons vs. Cubic Yards: Which Does Your Supplier Use?

Quarries and landscape suppliers sell gravel by the ton. Concrete suppliers sell by the cubic yard. Our calculator outputs both so you can order correctly regardless of how your supplier quotes. The conversion depends on material density — crushed stone is 1.4 tons per cubic yard, while lighter materials like decomposed granite run about 1.25 tons per yard. When in doubt, add 10–15% to your calculated amount to account for compaction loss and waste during delivery and spreading.

Gravel Coverage by Depth

One cubic yard covers different areas depending on how deep you spread it

Gravel Types and What to Use Each For

The type of gravel matters as much as the quantity — here is how to pick the right one
Gravel Type Size Best Use Compacts? Cost per Ton
Crushed stone (#57)3/4"Drainage, concrete base, drivewaysNo (free draining)$30–$55
Crusher run (ABC)0–3/4"Driveway base, compactable baseYes — ideal base$25–$45
Pea gravel3/8"Walkways, playgrounds, drainageNo — shifts$35–$55
River rock1–4"Decorative, erosion controlNo$45–$85
Rip rap4–18"Erosion control, slope stabilizationNo$40–$70

For a concrete base layer, always use crushed stone #57 — not pea gravel. Pea gravel is round and shifts under load, making a poor base. Crushed stone has angular edges that lock together and provide stable support. For a driveway base you want to compact, use crusher run — the mix of sizes compacts into a dense, stable layer.

Bags vs Bulk Gravel — Which to Buy

The break-even point where bulk delivery becomes cheaper than bagged stone
Buy bags when:
  • You need less than 1 cubic yard
  • No delivery truck access to your site
  • Multiple small separate areas
  • You need it immediately (no delivery wait)
Buy bulk when:
  • You need more than 2 cubic yards
  • Truck can reach your site
  • One continuous project area
  • Saving 40–60% vs bagged price matters

Bagged gravel (0.5 cu ft bags) costs about $5–7 per bag at big-box stores, which works out to $270–$380 per cubic yard. Bulk gravel delivered runs $40–$70 per cubic yard depending on type and your location. At 2+ yards the savings are significant. Call your local landscape supplier for a delivered price before buying bags for any project larger than a small walkway or flower bed border.

🚛 Truck Payload Reality Check

Concrete weighs 4,000 lbs per cubic yard. Here is what your truck can legally carry.
2026 Truck Max Payload Concrete Capacity Bag Capacity (80lb)
Toyota Tacoma (standard)1,521 lbs~0.38 cu yd~18 bags
Toyota Tacoma (i-FORCE MAX)1,705 lbs~0.42 cu yd~21 bags
Ford F-150 (PowerBoost Hybrid)1,740 lbs~0.43 cu yd~21 bags
Ford F-150 (5.0L V8)2,235 lbs~0.55 cu yd~27 bags
Ford F-150 (3.5L EcoBoost)2,440 lbs~0.61 cu yd~30 bags
3/4-ton (F-250, Silverado 2500)3,500+ lbs~0.87 cu yd~43 bags

*Payload values from 2026 manufacturer specs. Your actual payload is on the door-jamb sticker. Add accessories (toolbox, bedliner) and that number drops 100-300 lbs. A driver and passenger count against payload too.

If your project needs more than 1 cubic yard (4,000 lbs), pickup-truck delivery requires multiple trips. For 2+ cubic yards, ready-mix delivery is almost always cheaper than the gas, time, and suspension wear of multiple bag runs. Most ready-mix trucks deliver 8-10 yards in one trip.
