Countertop Measurements

|

Total surface area of your countertop. See "Additional Information" below for more information about how to calculate.

Perimeter of the countertop edge that will have an overhanging apron.

Percieved height of the countertop edge created by the overhanging apron, typically 3 – 9 inches.

Depth of the countertop apron, typically 1 – 2 inches.

Thickness of the countertop not accounting for the overhanging apron, typically 1 – 2 inches.
Total surface area of your countertop. See "Additional Information" below for more information about how to calculate.

Thickness of the countertop, typically 1 – 2 inches.
 
Dry mix needed:   lbs. (  bags)

*Calculations are based on the yield for a single 50# bag of Buddy Rhodes Craftsman Mix, GFRC Blended Mix, ECC Blended Mix, or equivalent when using GFRC or ECC Admixture Pack at recommended ratio.

How to Calculate Surface Area of a Complex Shape (example)

Step 1

An example "L-shaped" kitchen countertop schematic featuring a 45° corner, rounded edge, and knockout for a sink.

Step 2

We will consider the "full" countertop and the knockout areas separately.

Step 3

The countertop and knockout sections are broken into simple geometric shapes (rectangles, triangles, half-circles, etc.)

Step 4

Areas are calculated using appropriate formulas. The areas representing the countertop are added together, then the areas for the knockout sections are subtracted. In this example, the total surface area for the finished countertop is 5,220 in², or 36.25 ft²
