Crushed Stone vs Gravel: Differences and Best Uses
Crushed stone vs gravel: crushed stone is quarried rock broken by machines into angular pieces with sharp edges, while gravel usually refers to naturally rounded stones shaped by water and weather. The shape changes how they behave. Angular crushed stone locks together and resists shifting, making it better for bases and driveways. Rounded gravel rolls, drains, and looks natural but stays loose underfoot.

| Feature | Crushed stone | Natural gravel |
|---|---|---|
| Shape | Angular, fractured faces | Rounded, smooth |
| Source | Quarried and crushed | River beds, glacial deposits, pits |
| Interlock | High | Low |
| Compaction | Packs firm, especially with fines | Stays loose |
| Drainage | Good for clean grades | Very good |
| Look | Gray or quarry color, rough | Varied natural colors |

Which to use where
| Project | Better choice |
|---|---|
| Driveway base | Crushed stone |
| Driveway surface | Crushed stone with fines, or clean crushed stone |
| Paver or slab base | Crushed stone |
| French drains | Clean crushed stone or washed gravel |

Weight and cost
Both typically weigh roughly 1.3 to 1.5 tons per cubic yard depending on size and moisture. See gravel weight per yard. Common crushed stone is often among the least expensive aggregates near quarries, while decorative rounded stone can cost more due to screening and transport.
Building a driveway
Most durable gravel driveways use crushed stone for both base and top. See how to build a gravel driveway.
Bottom line
Crushed stone is angular and locks together, making it the go-to for driveways, bases, and anything that needs to stay put. Natural gravel is rounded, drains freely, and looks decorative but shifts. Ask suppliers about shape and size, since both are often called gravel.
