Square feet of coverage area ÷ coverage area per 1 ton = tons of rock needed. Using this formula, you can see that if you’re looking to cover 360 square feet with 1”-3” size rocks, you’re probably going to need 4.5 tons. If you’re using smaller materials, say 3/4”-1”, you may need only 3.6 tons.

Planning a Rock Landscaping Project
When you start planning a project that involves landscaping rock, a common question that we get asked is, how much landscaping rock do I need?
Rock Coverage Calculation
To calculate this size, measure the length and width of the project area. Multiplying those numbers will give you the square footage (or square meters for our metric friends).
Here is an example
You calculated you need 400 square feet of rock with a size of 1" to 3"/ You will need approximately 5 tons of rock. If you want to use a smaller material like ¾" to 1", you may only need 4 tons of rock.
How to determine how much gravel to use?
To determine how much gravel you need, determine the volume that the gravel must cover. To find the volume needed, determine the amount of area to be covered by gravel as well as the desired depth of the gravel. The ideal depth of gravel varies depending on the application, but a minimum of 2-4 inches of gravel is a workable baseline. Multiplying the area to be covered by the desired depth yields the volume of gravel you will need. Once the volume of gravel necessary is known, the known density of the given type of gravel can be used to calculate the mass of gravel needed to complete the project.
How are rock fragments classified?
Rock fragments are typically classified based on the size of the individual pieces that make up the aggregate. For example, sand is made up of rock fragments smaller than those in gravel, while gravel is smaller than cobbles, and cobbles are smaller than boulders. Size classifications of rock fragments (and gravel) can vary. Two commonly used standards are the Udden-Wentworth scale (a scale commonly used by geologists in the US) and the international standard, ISO 14688. In the Udden-Wentworth scale, gravel is categorized as granular gravel if it is 2-44 mm (0.079-0.157 in) in diameter or pebble gravel if it is 4-66 mm (0.2-2.5 in) in diameter. On the other hand, ISO 14688-1:2002 classifies gravel as fine (2.0-6.3 mm), medium (6.3-20 mm), or coarse gravel (20-63 mm).
What is gravel used for?
Gravel is a widely used commercial product that has a number of applications ranging from decorative purposes to large-scale construction , such as roads. Gravel and sand in billions of tons are produced for construction purposes worldwide each year.
Why is gravel used in construction?
This is because it provides a solid foundation while also containing enough cracks and spaces to allow water and excess moisture to drain.
What is river rock?
River stone, also referred to as river rock, is one of the largest types of gravel. River, creek, and beach stones are all the same form of naturally eroded stone. They tend to be used for decorative purposes due to their smooth surfaces and the variety of colors in which they can be found. For example, they may be used in landscaping or for lining water fixtures, creeks, and ponds due to their high draining capacity.
Can you use gravel as mulch?
In certain cases, gravel can also be used as a substitute for organic mulch. One of the advantages of using gravel over organic mulch is that it is more durable than organic mulches and requires less attention and replacement, while still providing protection for soil through heat retention and prevention of evaporation. Unlike many organic mulch types, gravel is also less prone to moving, so it is more likely to retain a desired shape or form when subjected to the elements.
Is gravel smoother than crushed stone?
Gravel formed as a result of natural erosion tends to be smoother and rounder while crushed stone will have rougher edges and be less smooth. This distinction is not always made, however, and because of the many different ways in which gravel is categorized, it is good practice to clarify exactly what kind of rock fragments are being used since different types of rock fragments or gravel have advantages and disadvantages depending on what they are being used for. Below are some examples of different types of gravel.
