Estimating your Granite Job

In order to determine the square footage needed for granite countertops, draw the kitchen and measure the back walls, and front of the counters. Square footage is determined by multiplying (in inches) the length times the width, then divide by 144 to get the sq. ft. When multiplying the width, make sure you add about 2 inches for granite overhang.

Backsplash should be measures the same way. For instance, if you have a 48 inch cabinet and want backsplash on the back wall of 4", you would take (48 x 4) / 144 - 1.3 sq. ft.

You can then take this sq. ft. and multiply it by the square foot price that the shop offers for stone and installation. Other costs would include undermount and topmount sink cutouts, cooktop cutouts, outlet cutouts, and the such.
