How many square feet does a ton of rock cover | what is the coverage of 1 ton of rock | rock coverage per ton at 1″, 2″, 3″, 4″, 6″, 8″, 10″, 12″ thick.

The coverage area of a ton of rock can vary significantly depending on the size and type of rock. On average, a ton of most decorative rocks or gravels typically covers about 100 square feet at a depth of 2 inches. However, for larger rocks or irregularly shaped stones, the coverage area may be less.

If you want to figure out how much rock you need, or estimate the required quantity of rock, gravel, chipping, pebbles or cobbles for your driveway, pathway, patio or for your planting area, you should know the dimension of your projects, what is their area and how your depth should be. How many square feet does a ton of rock cover and calculating the total amount of gravel you will need for your pathways can sometimes be overwhelming.

Rock is consist of fine to coarser aggregate formed of different size 10mm, 20mm, 40mm, and some are pea sizes gravel, others are pebbles. It is categorised as per shape and size.

Most common size of rock or stone which are used in construction are as fine gravel (4- 8 mm), medium gravel (8- 16 mm), coarse gravel (16- 32 mm), pebbles (32- 64 mm), cobbles (64 – 256 mm) and Boulder more than 256mm.

Gravel or coarse aggregate is one of the most important construction material required in every civil construction work, for landscaping projects, gravel rods, its required for fill the excavation area, used as backfills, required for preparing the concrete mix, it will be in round or oval, angular, pea size shaped gravel.

Density of gravel is unit weight define by mass by volume, measured in kg/m3, pound/ cubic yard, kg/ cubic feet, pound per cubic feet. In this article we know about “how many square feet does a ton of rock cover”. Required rock quantity calculate in volume and mass. Volume of gravel measured in cubic meter and cubic feet. Mass of gravel measured in tonne or in kg.

How many square feet does a ton of rock cover will depends on, thickness of your driveway, the size of gravel, rocks type igneous or metamorphic, loose and dense condition, compact, moisture content, dry and wet condition, others inorganic mixed in the gravel.

On average, one ton of rock weighs 2000 pound, and approximately yields 20 cubic feet or 0.74 cubic yards volume, and which will cover around 240 square feet at 1 inch thick.

**How many square feet does a ton of rock cover**

**Typical rock weighs about 2700 pound per yard, 100 pound per cubic foot, 2000 pound per ton.**

To calculate yields of one ton rock in yards, simply divide weight of 1 ton of rock i.e. 2,000 pound by weight of 1 yard of rock i.e. 2,700 = 2,000/ 2,700 = 0.74 cubic yards. 1 yards equals 27 cubic feet, so, amount of cubic feet in 0.74 yards = 0.74 × 27 = 20 cubic feet. Thus, one ton of rock yields 20 cubic feet or 0.74 cubic yards.

To calculate coverage of one ton of rock in square feet, convert the thickness of your projects in feet divide by 12, then divide the yields of 1 ton of rock i.e. 20 cubic feet by thickness in feet. For example, if thickness of your project is 2 inches, then thickness in feet = 2/ 12 = 0.166 feet, so, one ton rock coverage at 2 inches = 20/ 0.166 = 120 square feet.

**One ton rock coverage at 1 inch thick**

● 1) 1 inch thickness in feet = 1/12 = 0.0833

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 1 inch thick = 20/ 0.0833 = 240 square feet

● Thus, one ton of rock will cover approximately 240 square feet at 1 inch deep.

**One ton rock coverage at 2 inches thick**

● 1) 2 inches thickness in feet = 2/12 = 0.166

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 2 inches thick = 20/ 0.166 = 120 square feet

● Thus, one ton of rock will cover approximately 120 square feet at 2 inches deep.

**One ton rock coverage at 3 inches thick**

● 1) 3 inches thickness in feet = 3/12 = 0.25

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 3 inches thick = 20/ 0.25 = 80 square feet

● Thus, one ton of rock will cover approximately 80 square feet at 3 inches deep.

**One ton rock coverage at 4 inches thick**

● 1) 4 inches thickness in feet = 4/12 = 0.33

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 4 inches thick = 20/ 0.33 = 60 square feet

● Thus, one ton of rock will cover approximately 60 square feet at 4 inches deep.

**One ton rock coverage at 5 inches thick**

● 1) 5 inches thickness in feet = 5/12 = 0.416

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 5 inches thick = 20/ 0.416 = 50 square feet

● Thus, one ton of rock will cover approximately 50 square feet at 5 inches deep.

**One ton rock coverage at 6 inches thick**

● 1) 6 inches thickness in feet = 6/12 = 0.5

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 6 inches thick = 20/ 0.5 = 40 square feet

● Thus, one ton of rock will cover approximately 40 square feet at 6 inches deep.

**One ton rock coverage at 12 inches thick**

● 1) 12 inches thickness in feet = 12/12 = 1

● 2) One ton rock yields = (2000/ 2700) × 27 = 20 cubic feet or 0.74 yards

● 3) One ton rock coverage at 3 inches thick = 20/ 1 = 20 square feet

● Thus, one ton of rock will cover approximately 20 square feet at 12 inches deep.
