Wondering how many sq feet a ton of rock covers for your landscaping project? At rockscapes.net, we provide the expertise and resources you need to accurately estimate rock coverage, ensuring efficient and cost-effective landscaping. Let’s dive into the factors influencing rock coverage and how to calculate it effectively. This detailed guide will help you understand decorative rock, coverage area and project planning.
1. What Factors Determine How Many Square Feet a Ton of Rock Covers?
Several factors influence how many square feet a ton of rock can cover. The primary factors include rock size, rock type, and desired depth. Additionally, compaction and the shape of the rocks can play a role in the overall coverage achieved.
1.1. Rock Size and Coverage Area
Rock size significantly impacts coverage. Smaller rocks generally cover more area than larger rocks because they fill in gaps more efficiently. For instance, a ton of pea gravel will cover more square footage than a ton of large boulders. The following table illustrates the approximate coverage based on rock size:
| Rock Size | Approximate Coverage per Ton |
|---|---|
| Pea Gravel | 240 sq ft at 1″ depth |
| 1-2 inch rock | 120 sq ft at 2″ depth |
| 2-4 inch rock | 80 sq ft at 3″ depth |
| 4-6 inch rock | 60 sq ft at 4″ depth |
| 6-8 inch rock | 40 sq ft at 6″ depth |
1.2. Type of Rock and Its Impact on Coverage
The type of rock also affects coverage due to variations in density and shape. Denser rocks, like granite, will cover less area than lighter rocks, such as lava rock. The shape of the rock—whether it’s angular or rounded—also influences how well the rocks fit together, affecting overall coverage.
1.3. Desired Depth and Coverage Area
The desired depth of the rock layer is a critical factor. A thicker layer of rock will cover less area. For example, if you want a 2-inch layer of rock, a ton of material will cover half the area it would if you only wanted a 1-inch layer. Use the following formula to estimate the required amount of rock:
Area (sq ft) = Rock Weight (tons) / (Depth (inches) / 12) x Coverage Factor
Where the Coverage Factor depends on the type and size of rock.
