            The Basic Formula for calculating yardage is:

                                      (Length in feet x Width in feet x Depth in inches) /  324   =    Yards  needed     

Retaining Walls and Paving System Estimation Help


Paver square footage - (L' x W') + 10%                                          for cuts.  


Retaining Wall           - Height of wall in

Square Footage            feet x length of  wall                                       Include what is buried                                           beneath grade.


To figure out how many caps you will need, find the linear footage of your retaining wall.  Then divide the number by the caps length in feet.  Add a couple of caps for cuts and corners.

​Formulas and Facts

Area of a Circle



Square Footage = 3.14 x (radius squared)

                          = 3.14 x (radius x radius)  

Radius is the distance from the center of the circle to the outside of the circle.  It is half of the width of the entire circle.


If your circle is 24' across, the radius is 12'.  So the area is:

Square Footage = 3.14 x (12 x 12)

                             = 3.14 x (144)

                  = 452.16

So the area of a 24' circle is 452.16 sqare feet.
