Types of Gravel: A Buyer's Guide

Gravel comes in many sizes and shapes, and the right one depends on the job. Here are the common types of gravel in Canada, what each is best for, and how to pick.

The main types of gravel

TypeSize / shapeBest for
Crusher run (3/4 minus, Granular A)Crushed + dustDriveway and slab bases — compacts hard
3/4" clear stone19 mm, no finesDrainage, French drains, top layers
Pea gravelRounded, 3/8"Patios, paths, play areas, decoration
River rockRounded, 1–5"Landscaping beds, dry creek beds, accents
Crushed limestoneAngular, light greyPaths and surfaces that pack tight
Pit run / Granular BCoarse mixedCheap deep sub-base fill

Angular vs rounded — the key choice

Angular crushed stone (crusher run, clear stone, limestone) has sharp faces that lock together and compact, so it is the choice for any load-bearing or structural job — driveways, slab bases, paths. Rounded stone (pea gravel, river rock) looks great and is comfortable underfoot but will not compact, so keep it decorative or use it where drainage matters more than stability.

Gravel sizes explained

  • Fines / stone dust: packs joints; mixed into crusher run.
  • 3/8 in (pea gravel): small, smooth, easy to walk on.
  • 3/4 in (19 mm): the all-rounder for bases and drainage.
  • 1–2 in: drainage and decorative cover.
  • 2–5 in: river rock and large decorative stone.

To choose for a specific project, see best gravel for driveways, crushed stone vs gravel, and the gravel depth guide. Then size your order with the Crushed Gravel Calculator.

Frequently asked questions

What are the main types of gravel?

The common ones are crusher run (3/4 minus / Granular A) for bases, 3/4 inch clear stone for drainage, pea gravel and river rock for decoration, crushed limestone for tight-packing surfaces, and pit run (Granular B) for cheap sub-base fill.

What is the difference between angular and rounded gravel?

Angular crushed stone has sharp faces that lock together and compact, so it suits driveways, slab bases and paths. Rounded stone like pea gravel and river rock will not compact, so it is best used decoratively or where drainage matters most.

What size gravel is best for a driveway?

Use 3/4 inch crusher run for the compacting base and 3/4 inch clear stone or crushed limestone for the top. Avoid pea gravel and river rock as a driving surface because round stone ruts and scatters.

What is crusher run gravel used for?

Crusher run — crushed stone mixed with stone dust, also called 3/4 minus or Granular A — is the standard base material for driveways, shed pads and slabs because the dust fills the gaps so it compacts rock hard.
