Estimating the Amount of Stone Required
Instructions
- Measure the length times the height to arrive at the gross square footage of flat stone needed.
- Subtract square footage for windows, doors and other openings.
- Measure the linear feet of outside corners to determine the amount of corner pieces needed (one linear foot of corner pieces covers approximately 3⁄4of a square foot of flat area).
- Subtract the flat area covered by the linear feet of corner pieces from the square footage of flat stone required.
- Note: You may wish to obtain some extra stone to allow for cutting and trimming. In addition, be sure to verify whether the texture chosen is sold based on coverage with a 1⁄2" mortar joint or tight-fitted. Most texture coverages are listed for a 1⁄2" joint.
Formula
Length x Height = Wall Area
Window Width x Window Height = Window Area
Lineal Feet of Corners Required x .75 = Wall Area Covered by Corners
Wall Area - Window Area - Wall Area Covered by Corners = Square Ft. Flats Required
