Enter the length of coverage (m) and the width of coverage (m) into the Calculator. The calculator will evaluate the Pebble Coverage. 

Pebble Coverage Formula

PC = L * W *75

Variables:

  • PC is the Pebble Coverage (kg of pebbles needed)
  • L is the length of coverage (m)
  • W is the width of coverage (m)

To calculate Pebble Coverage, multiply the length by the width, then multiply again by 75 to get the kilograms of pebbles needed.

How to Calculate Pebble Coverage?

The following steps outline how to calculate the Pebble Coverage.


  1. First, determine the length of coverage (m). 
  2. Next, determine the width of coverage (m). 
  3. Next, gather the formula from above = PC = L * W *75.
  4. Finally, calculate the Pebble Coverage.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

length of coverage (m) = 30

width of coverage (m) = 50

FAQs

What factors can affect pebble coverage calculations?

Different factors such as the shape and size of the pebbles, the depth of the coverage area, and the surface underneath the pebbles can all affect the accuracy of pebble coverage calculations.

How can I ensure I’m purchasing the correct amount of pebbles for my project?

It’s recommended to add an extra 10-20% more pebbles than calculated to account for variations in coverage depth and compaction. Also, consulting with a landscaping professional can provide more tailored advice.

Are there different types of pebbles that require different calculations?

Yes, pebble types vary in density and size, which can affect the coverage. It’s important to use the specific calculator or formula tailored to the type of pebbles you’re using.

Can the pebble coverage formula be used for other types of landscaping materials?

While the formula provides a basic guideline, different materials such as mulch, sand, or gravel may have different densities and require adjusted calculations. It’s best to use calculators specifically designed for each material.
