How To Calculate the Square footage of countertops
Notes:  Standard width of countertop = 26 inches  Standard height of splash = 4 inches
A. Square inches of splash  Length of back splash + Length of end splash = total splash length  Total splash length x 4 in = sq in of splash B. Square inches of countertop  Length of counter x 26 in = sq in of countertop C. Square inches of bar area  Length of bar at longest point x Width of bar at widest point = sq in of bar
Total square footage = (A + B + C) divided by 144
