If you are interested in hiring a professional to estimate your material and installation costs then find a contractor and request a block wall installation estimate.
Calculating the Number of Capstones. To figure the number of capstones needed, dividing the length of the wall in feet by the length of the capstones in inches, then multiply by 12. For example, if the wall is 20 feet long and the capstones are 8 inches wide, then the number of capstones needed is [20/8](12) = 30.ultiply the wall's length by its height plus 1/2 a foot to find the total square footage of the wall. That is, calculate. Wall Area = L(H + 0.5) sq. ft, where L is the length of the wall in feet and H is the finished height of the wall in feet.
