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


  • 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
