How To Figure Out Countertop Square Footage

Calculating countertop square footage is essential for accurately estimating material costs and planning your kitchen remodel. Here's a comprehensive guide to help you determine the square footage of your countertops:

Step 1: Measure the Length and Width

Start by measuring the length and width of each individual countertop section. Use a measuring tape or laser measure and record the measurements in feet or inches.

Step 2: Convert Measurements to Feet

If your measurements are in inches, convert them to feet by dividing by 12. Example: 72 inches = 6 feet.

Step 3: Calculate Rectangle Area

For rectangular countertops, multiply the length by the width to obtain the area in square feet. Example: 6 ft x 4 ft = 24 square feet.

Step 4: Calculate Triangle Area

For triangular countertops, use the formula Area = (1/2) x base x height. Measure the base and height of the triangle and substitute the values. Example: 5 ft base x 3 ft height = 7.5 square feet.

Step 5: Calculate "L" or "U" Shaped Countertops

For "L" or "U" shaped countertops, treat each section as a separate rectangle or triangle and add their areas together. Example: 12 ft rectangular section + 6 ft triangular section = 18 square feet.

Step 6: Calculate Island Area

If you have a kitchen island, measure its length and width as if it were a rectangle. Then, multiply the measurements to get the area in square feet.

Step 7: Add Up All Areas

Once you have calculated the area of each countertop section, add them together to get the total square footage of your countertops.

Step 8: Allow for Overhang and Seams

Add an additional 10-15% to the total square footage to account for countertop overhangs and seams. This will ensure you have enough material for a professional finish.
