Kitchen Platform Countertop Calculator

HOW TO CALCULATE GRANITE FOR KITCHEN COUNTERTOPS

Material required for a countertop involves calculating the total surface area of the countertop, considering its shape and dimensions.

Identify the shape and dimensions, then break irregular layouts into simpler rectangles for measuring.

1. Identify the shape and dimensions of the countertop.
2. Divide irregular shapes into simpler sections (rectangles or squares) and take the dimensions of each section/piece.
3. Calculate the area of each section.
4. Add the areas together to find the total surface area.

Step 1: Select the Countertop Shape

Choose a countertop shape. An image will display to help you visualize it.

• L-Shape
• U-Shape
• I-Shape (Straight Countertop)
• Parallel / Galley Platform
• Island Countertop

Step 2: Select the Unit of Measurement

• Centimeters
• Inches

Step 3: Input Dimensions

• L-Shape Countertop: Enter the Length and Width for Rectangle 1 (R1), Rectangle 2 (R2), and/or Rectangle 3 (R3). The calculator will sum the areas.
• U-Shape Countertop: Enter the Length and Width for the Right Rectangle, Central Rectangle, and Left Rectangle. The total area is the sum of all rectangles.
• I-Shape Countertop: Enter the Length and Width of the single rectangle representing the countertop.
• Island Countertop: Enter the Length and Width of the island rectangle.
• Galley/Parallel: Enter the Length and Width for the two rectangles representing parallel counters.

Step 4: View Total Material Area

The calculator displays total area in square feet and square meters, based on the selected unit.

Step 5: Use the Results

• Use the total area to determine the quantity of countertop material required.
• Tip: Add 10%-15% for cutting and fitting wastage when purchasing materials.
