How Many Square Feet Does a Ton of Rock Cover?
A ton of landscape rock covers roughly 70–100 square feet at 2 inches deep — but the exact number swings with stone size and depth. Here is the full breakdown so your beds and borders come out right.
Landscape rock is priced by the ton, so before you order you need to know how far a ton goes. The honest answer is that it depends on two things: how big the rock is and how deep you spread it. As a rule of thumb, one ton covers about 70–100 square feet at 2 inches deep — but small decorative stone stretches further and large boulders-in-miniature cover far less.
Coverage by Rock Size (at 2" Deep)
Bigger stones leave bigger voids and weigh more each, so a ton holds fewer pieces and covers less ground. This is the biggest reason two "one-ton" orders can cover very different areas.
| Rock size | Coverage per ton (2") | Common use |
|---|---|---|
| Screenings / ⅜" | ≈ 110–120 sq ft | Pathways, fine ground cover |
| Small (½–1½") | ≈ 100–120 sq ft | Beds, borders, small river rock |
| Medium (1½–3") | ≈ 80–100 sq ft | Decorative river rock, drainage |
| Large (3–5") | ≈ 60–80 sq ft | Accent rock, dry creek beds |
| Very large (6"+) | ≈ 25–50 sq ft | Feature stone, erosion control |
For a specific stone, the rock calculator and river rock calculator apply the right density automatically.
Coverage by Depth
Depth scales coverage inversely — double the depth and you halve the area a ton covers. These figures use a typical medium rock at about 1.45 tons per cubic yard.
| Depth | Coverage per ton |
|---|---|
| 2 inches | ≈ 90 sq ft |
| 3 inches | ≈ 60 sq ft |
| 4 inches | ≈ 45 sq ft |
Turning Area Into Tons
To flip the question and find how many tons your project needs, work from area to volume to weight:
Tons = (Area sq ft × Depth in feet ÷ 27) × 1.45
Example: 200 sq ft × 0.25 ft (3 in) ÷ 27 × 1.45 ≈ 2.7 tons
The stone coverage calculator does this both ways — area to tons, or tons to area. Not sure which rock to choose? Compare options in our guides on river rock vs gravel and pea gravel vs river rock.

Rock spread over bare soil sinks and scatters. A heavy-duty landscape fabric gives it a stable mat and blocks weeds, while a contractor wheelbarrow makes moving a dense ton of stone far less punishing.
Heavy-Duty Landscape Fabric
Keeps rock from sinking into soil and blocks weeds from growing through.
