To Calculate Yardage needed for your project enter the Width of Circle, the Width of Border, and Depth.
Note: you must enter your Depth Key Code Value into the "Circular Border Calculator" for Correct Calculation.
Example: there is a Circular shaped pool 20 feet wide diameter the owner wants to put in a 2 foot wide border (or walkway) of stone around the pool and would like it to be 3 inches deep (see Depth Key Code).
