Calculating the square footage of a wall is a simple and essential skill for any homeowner or DIY enthusiast. Whether you need to determine how much paint, wallpaper, or paneling you’ll require, knowing the surface area of your wall will help you save time, energy, and money. This article will guide you through the process of calculating the square footage of a wall in just a few easy steps.
Step 1: Gather your materials
To get started, you’ll first need to gather some basic tools:
– A measuring tape
– A pen/pencil and paper or notes app on your phone
– A calculator
Step 2: Measure the height and width of the wall
Using your measuring tape, carefully measure both the height and width of the wall. Make sure that your tape is straight and level as any slant or curve can lead to inaccurate measurements. Once you’ve measured both dimensions, write them down for future reference.
Height: _______ feet
Width: _______ feet
*Note: If your measurements are in inches, simply convert them to feet by dividing by 12 (i.e., if your measurement is 84 inches, divide by 12 to get 7 feet).
Step 3: Multiply height by width
Now that you have both measurements recorded, it’s time to calculate the total square footage of your wall. Multiply the height (in feet) by the width (in feet) to obtain the area in square feet.
Area (square footage) = Height x Width
For example, if your wall measures 8 feet in height and 12 feet in width,
Area (square footage) = 8 ft x 12 ft = 96 square feet
Step 4: Consider irregularities
If your wall has any irregular shapes like windows or doors that you won’t be painting or covering with material, you need to subtract their respective areas from the total square footage. To do this, measure the height and width of each irregular shape, multiply them together, and then subtract this area from your wall’s total square footage.
For example, if there is a 3 ft x 4 ft window on your wall,
Area of the window: 3 ft x 4 ft = 12 sq ft
Adjusted wall square footage = Total wall square footage – Area of window
Adjusted wall square footage = 96 sq ft – 12 sq ft = 84 sq ft
Step 5: Plan for extra
It’s always a good idea to add an extra 10-15% to your calculations to account for any discrepancies or unexpected complications. This will ensure that you have enough material on hand to finish your project without any hiccups.
Using the adjusted square footage from step 4, add an extra percentage:
Adjusted wall square footage with extra = Adjusted wall square footage x (1 + Extra percentage)
For example:
Adjusted wall square footage with extra = 84 sq ft x 1.15 = 96.6 sq ft
Now you know how to calculate the square footage of a wall! With this knowledge in hand, you can confidently plan for your next DIY project involving painting, covering, or installing new materials on your walls. No more worrying about running out of paint or buying too much wallpaper – just follow these easy steps for accurate results every time.
