Types of Gravel and Sizes: Which Should You Use?
Gravel names vary by region and supplier, but a few materials cover most projects. Choosing the right one affects how well the surface holds up, how it drains, and how much you pay.
Common gravel types at a glance
| Type | Typical size | Best for | Notes |
|---|---|---|---|
| Crushed stone (#57) | About 3/4 in | Driveways, drainage, base layers | Angular, locks together when compacted |
| Crusher run | 3/4 in minus, with fines | Driveway and patio base | Packs very firm; drains poorly compared with clean stone |
| Pea gravel | About 3/8 in, rounded | Paths, play areas, decorative beds | Smooth and comfortable, but shifts underfoot |
| River rock | 1–3 in and larger | Decorative beds, dry creek beds | Rounded and attractive, not for driving on |
| Decomposed granite | 1/4 in and smaller | Garden paths, patios | Compacts to a firm surface, can wash away in heavy rain |
Sizes are approximate. Grading names and stone sizes differ between suppliers, so confirm what you are buying.
How to choose
- Driveways: angular crushed stone compacts and interlocks, which is why it is the standard choice. A common build is a coarser base topped with a finer layer.
- Drainage: clean, washed crushed stone has open gaps between pieces so water passes through. Material with lots of fines holds water.
- Walkways and patios: smaller, finer stone is more comfortable to walk on and sets more evenly.
- Decoration: rounded stone such as river rock or pea gravel looks best in beds but moves easily, so it suits low-traffic areas.
Size affects weight and coverage
Different stone weighs different amounts per cubic yard, typically between 2,600 and 2,800 pounds. That changes how many tons you order for the same volume.
