The short answer
For most UK driveways the gravel that works best is an angular crushed stone around 10–20mm. Angular stones interlock and bind together when compacted, so they stay put under tyres, whereas rounded gravel like pea shingle rolls and scatters — fine on a path, poor on a driveway, and worse on a slope. The 10–20mm size is the sweet spot: large enough not to lodge in tyre treads, small enough to pack into a comfortable surface. For a firmer finish you can use a self-binding gravel (a gravel, sand and clay mix that compacts solid), and decorative aggregates such as Cotswold or granite chippings add a few pounds per m² for looks. The single biggest factor in how the stone performs, though, is the sub-base and membrane underneath it.
The gravel you can see is only part of the story, but choosing the right type makes the difference between a driveway that holds together and one that scatters across the lawn. Here is what to pick.

Angular versus rounded, and the right size
Angular gravel — crushed stone with flat faces and edges — interlocks when it is compacted, so it grips under tyres and resists migrating. Rounded gravel, like pea shingle, behaves more like ball bearings: each smooth stone rolls, so it scatters at the edges and never feels stable, especially on a slope. Size matters too: somewhere between 10mm and 20mm is the sweet spot, big enough that stones do not jam in tyre treads but small enough to pack into a comfortable surface to drive and walk on. Below that, gravel migrates easily; much above it and the surface is loose and uncomfortable.
| Gravel type | Driveway suitability | Notes |
|---|---|---|
| Angular 10–20mm | best all-round | interlocks, stays put |
| Rounded / pea shingle | poor | rolls & scatters, worse on slopes |
| Self-binding gravel | good (firm finish) | gravel/sand/clay, compacts solid |
| Decorative chippings | good | looks; check size is driveway-grade |

Why the base matters more than the stone
It is tempting to focus on the colour and type of gravel, but the surface only performs as well as what is beneath it. A driveway built on a compacted MOT Type 1 sub-base with a geotextile membrane and only 40–60mm of gravel on top will hold its shape; the same gravel laid thick on bare soil will rut and sink. So choose an angular 10–20mm stone you like the look of, but spend the budget on the groundwork — that is what decides whether the gravel stays where you put it.

Frequently asked questions
What is the best gravel for a driveway?
An angular crushed stone around 10–20mm is best for most UK driveways, because angular stones interlock and stay put under tyres. Rounded gravel like pea shingle rolls and scatters, so it is a poor choice for a driveway, especially on a slope.
What size gravel is best for a driveway?
Around 10–20mm is the sweet spot — large enough that stones do not lodge in tyre treads, but small enough to pack into a comfortable, stable surface. Smaller migrates easily; much larger feels loose.
Is self-binding gravel good for a driveway?
Yes — self-binding gravel is a pre-mixed gravel, sand and clay that compacts into a firmer, more solid surface than loose stone, which helps keep the gravel in place. It gives a tidier finish where you want less movement.
