Measuring & Computing the Total Square Footage/Cost

Figuring out the Square Footage of the counters

Take measurements of the total length of each piece of countertop you want granite on. This measurement should be along the back where the top meets the wall. NOTE: You can either convert, the linear inches for length and width, to feet, and then compute the square feet, or you can compute the square inches and then divide by 144, to work out the square feet (FYI 1 foot = 12 inches); and
Now measure the width (including the overhang, you desire) of the countertops.

[Typically, we multiply the length by 25.5 inches (since most cabinets are 24 inches + over hang of 1.5 inches). Divide the result by 144 to arrive at the square feet of granite. Example: total length (102 + 60 + 18) x 25.5 = 4590 /144 = 31.9 sq ft. In this example, the Total Length = 180 inches (15 feet) x Total Width = 25.5 inches (2.125 feet) = 15 (L) x 2.1 25 (W) = 31.875 sq.ft or rounded up to 31.9 sq. ft.]

Then, the Back-Splash …..

If you want to include a back-splash multiply the length along the wall by 4 inches (the industry default is 4”, unless otherwise specified).

Example: Total length x Width, (25.5 + 126 + 108) x 4 = Total Length = 259.5 inches (21.625 feet) x Total Width = 4 inches (0.33333 feet) = 21.625 (L) x 0.333333 (W) = 7.21 square feet

Finally, the Island and/or Bar

If you have an island or a bar top you need to measure the length times the width, to arrive at the square feet area.

Example

(78″ x 48″)/144 = 26 sq ft Example: Total Length =78 inches (6.5 feet) x Total Width = 48 inches (4 feet) = 6.5 (L) x 4 (W) = 26 square feet

From the above example, we have

*Surface*	*Length*	*Width*	*Area*
*Counters*	15.00	2.13	31.88
*Back-Splash*	21.63	0.33	7.21
*Island*	6.50	4.00	26.00
*Total Square Feet*			*65.08*
