How To Calculate Countertop Sq Ft

Calculating the square footage of your countertops is a crucial step in planning your kitchen or bathroom renovation. Accurate measurements ensure you order the correct amount of material and avoid costly mistakes. Here's a step-by-step guide to help you determine the square footage of your countertops:

Step 1: Measure the Perimeter

Start by measuring the perimeter of your countertops. Use a measuring tape to measure around the outside edge, including any cutouts for sinks or appliances. Record these measurements in inches.

Step 2: Convert Inches to Feet

Divide the perimeter measurements by 12 to convert them from inches to feet. This gives you the perimeter of your countertops in feet.

Step 3: Calculate the Area

Next, calculate the area of your countertops. For rectangular or square countertops, simply multiply the length by the width. For irregular or L-shaped countertops, divide them into smaller sections and calculate the area of each section separately. Then, add up the areas of all the sections to get the total countertop area.

Step 4: Convert Square Feet to Square Inches

Finally, convert the countertop area from square feet to square inches by multiplying it by 144. This gives you the total square inches of your countertops.

Example:

Let's say you have a rectangular countertop that measures 10 feet long and 5 feet wide. Here's how you would calculate the square footage:

Perimeter = 2(10) + 2(5) = 30 feet
Area = 10 x 5 = 50 square feet
Total Square Inches = 50 x 144 = 7,200 square inches

Tips:

Always round up your measurements to the nearest inch to ensure you have enough material.
If your countertops have any curves or complex shapes, it's best to consult a professional for accurate measurements.
Consider the overhang when calculating the square footage. The overhang is the portion of the countertop that extends beyond the cabinets.
Add 10-15% to the total square footage for waste and cutting.
