How To Determine Siding Square Footage

Alright, gather 'round, folks! Let's talk siding. Not just any siding, but the square footage of siding. Why? Because unless you’re planning on just stapling a single, lonely vinyl plank to your house and calling it a day (please don't!), you're gonna need to know how much to buy. And trust me, accidentally buying too little siding is a special kind of home improvement purgatory. You'll be staring at that bare patch of wall, questioning all your life choices, while squirrels judge you silently.

So, how do we avoid this existential siding crisis? By learning to calculate square footage, that's how! It's not as scary as it sounds, I promise. Think of it like advanced connect-the-dots, but with rulers and slightly more math. Less fun for kids, exponentially more useful for adulting.

The Great Wall Measurement Extravaganza: Your Tools of the Trade

First, you need your supplies. You wouldn’t go to war without a sword (or at least a sternly worded letter), and you can't measure siding without the proper equipment. Here's your arsenal:

• A measuring tape: This is your Excalibur. Get a good one, at least 25 feet long. Trust me, you don't want to be making multiple trips to the hardware store because your tape measure is shorter than a dachshund.
• A notepad and pen: Because even if you think you’ll remember everything, you won’t. Unless you have a photographic memory, in which case, why are you reading this? Go cure cancer or something!
• A calculator: Unless you enjoy long division (in which case, seek help), grab a calculator. Your phone has one, your computer has one, even your toaster might have one these days. Embrace the technology!
• A buddy: Optional, but highly recommended. Holding a long tape measure while balancing on a rickety ladder is a two-person job. Plus, having someone there to question your life choices ("Are you sure that ladder is stable?") can be surprisingly helpful.

Step 1: Measure Each Wall Like Your Life Depends On It (Because, Kind Of, It Does)

Okay, let's get down to brass tacks. Start with one wall of your house. Measure the length of the wall from one corner to the other. Write it down! Then, measure the height of the wall from the ground to the eaves (that's the part where the roof overhangs). Write that down too!

Now, multiply those two numbers together: Length x Height = Area. This is the square footage of that wall. Woohoo! You're officially a siding square footage superstar!

Repeat this process for every wall of your house. Yes, even that tiny little wall next to the back door. Every square inch counts! It's like counting sheep, but with numbers and the looming threat of insufficient siding.

Step 2: The Great Window and Door Deduction (No, You Can't Just Ignore Them)

Now, the tricky part. Unless your house is a minimalist cube with no windows or doors (in which case, congrats on achieving peak boring!), you'll need to subtract the square footage of those openings. You wouldn’t want to order siding for your windows, would you? Unless you're going for that "sealed-off bunker" aesthetic. Which, hey, no judgment.

For each window and door:

• Measure the width and height.
• Multiply them together: Width x Height = Area.
• Write down the square footage of each window and door.

Once you’ve measured all the windows and doors on a wall, add up their square footage. Then, subtract that total from the total square footage of the wall. This gives you the actual square footage of siding you need for that wall.

Example: Let's say a wall is 20 feet long and 10 feet high. That's 200 square feet. But it has a window that's 3 feet wide and 4 feet high. That's 12 square feet. So, the siding square footage for that wall is 200 - 12 = 188 square feet. See? Not rocket science. Unless you're siding a rocket. In which case, I’m definitely not qualified to help.

Step 3: Adding It All Up (Like a Siding Accountant)

Once you’ve calculated the siding square footage for all the walls, add them all together. This is your total siding square footage! Congratulations, you've officially conquered the square footage beast! Go celebrate with a victory nap (or a large pizza, I won't judge).

Step 4: The Overlap Factor (Because Siding Isn't Magic)

Hold on, don't order that siding just yet! There's one more crucial step: accounting for overlap. Siding isn’t like wallpaper; it overlaps slightly when it's installed. This means you need to order more than just your calculated square footage.

The amount of overlap depends on the type of siding you're using. A good rule of thumb is to add 5-10% to your total square footage. This is called the waste factor. It also accounts for cuts you’ll have to make to fit the siding, and any mistakes (we all make them, even siding experts!).

To calculate the extra siding you need, multiply your total square footage by 0.05 (for 5%) or 0.10 (for 10%). Add that number to your total square footage. That's the final amount of siding you need to order.

Example: Let's say your total siding square footage is 1000 square feet. Adding a 10% waste factor means you need to order 1000 x 0.10 = 100 square feet extra. So, you need to order 1100 square feet of siding.

Bonus Tip: When in Doubt, Round Up (Because It's Better to Have Too Much Than Too Little)

Siding is usually sold in increments, like squares or bundles. When you're placing your order, it's always better to round up to the nearest increment. Trust me, having a few extra pieces of siding is way better than running short halfway through the job. You can always use the extra siding to build a tiny siding fort for your pet hamster. Or, you know, store it in the garage.

Siding Square Footage: You Did It!

There you have it! You’ve successfully navigated the treacherous waters of siding square footage calculation. Now you can confidently stroll into your local hardware store, armed with your numbers and your newfound knowledge, and order the perfect amount of siding for your house. And when those squirrels start eyeing your siding-protected walls, you can just smile and say, "Bring it on!"

Just remember to double-check your measurements, account for those windows and doors, factor in the overlap, and round up when in doubt. And if all else fails, hire a professional. Because sometimes, the best DIY project is the one you don't do yourself.
