Sketch a diagram of your countertop area, including the backsplash, and measure the length from wall to wall. Measure the depth from the wall to the edge (standard kitchen counters are about 25½ inches deep). Mark the locations and dimensions of sinks and cooktops, and calculate the area by multiplying length by depth and dividing by 144 to convert square inches to square feet. Include backsplash height in your drawing. Our professional measure techs (templators) will take precise digital measurements before fabrication.
