Gravel vs crushed stone
The words get used interchangeably at the supply yard, but they describe two different materials with opposite strengths: gravel is round, crushed stone is angular. Shape drives everything — compaction, drainage, comfort, and which project each belongs in.
Where each comes from
Gravel is nature's product: rock tumbled round by rivers, glaciers, and time, dredged or dug from deposits. Crushed stone is manufacturing: quarried rock fed through crushers, producing angular fragments with sharp fractured faces and — depending on the grade — fine "dust" mixed in.
Shape is performance
| Property | Gravel (round) | Crushed stone (angular) |
|---|---|---|
| Compacts? | No — pieces roll past each other | Yes — faces interlock (especially with fines) |
| Drainage | Good; water flows between stones | Good washed; slow with fines |
| Underfoot | Comfortable, loose | Firm, locks into a surface |
| Under tires | Ruts and scatters | Holds a shape |
| Look | Soft, natural, decorative | Industrial, textured |
| Stays put? | Needs edging — migrates | Self-constraining |
Which one your project needs
- Driveway, road, paver base, shed pad: crushed stone (crusher run base + #57/#67 top). Structure demands interlock. Driveway quantities →
- Walkways, play areas, decorative beds: pea gravel — comfort and looks are the job. Pea gravel quantities →
- French drains, retaining-wall backfill: washed crushed stone (#57/#4) — angular voids move water; fines would clog. Drain quantities →
- Aquariums: washed round or pea-size substrate — comfort for fish, not load-bearing. Tank quantities →
The cost angle
Crushed stone is usually cheaper per ton than decorative pea gravel (quarries make it in bulk), but it's sold almost exclusively by the ton while pea gravel is commonly bagged — so the "expensive" one often depends on how you buy it. Price both honestly with the cost calculator, and see the crushed gravel calculator or the pea gravel calculator for quantities.
