How To Measure For Rv Slide Out Awnings

So, you’re thinking about RV slide out awnings? Awesome! These little guys are game-changers. Seriously. No more leaves, twigs, or shudder bird droppings jamming up your slide out. Plus, they look pretty darn cool.
But first, you gotta measure. Don't worry, it's not rocket science. More like... advanced-level measuring tape wrangling. Let’s dive in!
Why Bother Measuring, Anyway?
Good question! Imagine buying a perfectly adorable awning, only to discover it's three inches too short. Disaster! Wasted money! A deeply unsatisfying afternoon! Accurate measurements are your best friend. They'll ensure a perfect fit and a happy RV-ing experience.
Must Read
Think of it like this: measuring is like finding the perfect pair of socks. Too big, and they bunch up. Too small, and your toes scream. Just right? Pure bliss. Same goes for RV awnings.
Gear Up: What You’ll Need
Before you transform into a measuring wizard, gather your supplies. It's like prepping for a mini-adventure! Here's the list:
- A reliable measuring tape. The longer, the better. Trust me. You don't want to be making multiple trips.
- A trusty ladder. Safety first, always! We're aiming for awning bliss, not emergency room visits.
- A notepad and pen (or your phone). Write it all down! Don’t rely on your memory, unless you're some kind of superhuman measurement savant.
- A friend! This is optional, but highly recommended. An extra set of hands (and eyes) can be a lifesaver. Plus, moral support is always appreciated.
- Snacks! Measuring can be surprisingly tiring. Reward yourself with something tasty.
Pro-Tip: Wear comfortable shoes. You'll be doing some climbing and crouching. Treat your feet kindly.
Let's Get Measuring! The Step-by-Step Guide
Okay, deep breath. We're doing this! Follow these steps, and you’ll be a slide out awning measuring pro in no time.
Step 1: Measure the Slide Out Box Width
This is the big one. We're talking about the overall width of the slide out box itself. Not just the exposed part, but the entire thing, from outer edge to outer edge.

Climb up that ladder (carefully!) and stretch that measuring tape across the top of the slide out box. Make sure you're measuring in a straight line. We want accuracy, people!
Record that number! This is your most important measurement.
Fun Fact: Did you know some slide out awnings are custom-made? That's right! You can get an awning tailored specifically to your RV. Fancy!
Step 2: Measure the Extension of the Slide Out
Now, we need to know how far that slide out actually… slides out. This determines how much fabric your awning needs to cover.
Extend your slide out completely. Then, measure from the RV wall to the outermost edge of the slide out box. Again, straight line, people! Accuracy is key!
Write that number down! You’re doing great!

Quirky Detail: Ever wondered what happens if you forget to retract your slide out awning before driving? Let’s just say it’s not pretty. Don’t do it!
Step 3: Consider the Mounting Location
Where will the awning actually attach to your RV? This is crucial for making sure everything lines up correctly.
Look for a flat, solid surface above the slide out. This is where the awning rail will be mounted. Measure the distance from the top of the slide out to this mounting location.
Why does this matter? Because you need to ensure the awning fabric will extend far enough to properly cover the slide out when it's extended. You don't want rain or debris sneaking in!
Important Note: Obstructions! Are there any lights, antennas, or other things in the way? Note them down! You might need to adjust your mounting location or choose a different awning style.

Step 4: Double-Check, Triple-Check!
Seriously, go back and measure everything again. And then maybe one more time for good measure (pun intended!).
It’s much better to be overly cautious than to end up with an awning that doesn't fit. Trust me, your future self will thank you.
Funny Story: I once spent an entire afternoon installing an awning, only to realize I'd measured everything in inches instead of feet. Rookie mistake! Learn from my pain!
Choosing the Right Awning Size
Okay, you've got your measurements. Now what? Time to shop!
Most RV awning manufacturers will have sizing charts or guides. Use your measurements to determine the best fit. Don't be afraid to call them if you have any questions. They’re there to help!
A word of caution: It’s generally better to go slightly larger than slightly smaller. A little extra coverage is always a good thing. But don't go overboard! We're aiming for a snug fit, not a giant parachute.

Consider the Fabric: Awning fabrics come in all sorts of colors and materials. Choose something that complements your RV's style and can withstand the elements.
Installation Tips
Once your awning arrives, it’s time for the big install! Here are a few pointers:
- Read the instructions carefully! I know, it’s tempting to just dive in. But trust me, the instructions are there for a reason.
- Gather all your tools before you start. Nothing’s worse than being halfway through a project and realizing you’re missing a crucial screwdriver.
- Take your time. Don’t rush! A rushed installation is a recipe for disaster.
- Enlist a friend! Again, an extra set of hands (and eyes) is invaluable.
Safety First! Wear safety glasses and gloves. And don't forget to disconnect the power to your RV before doing any electrical work (if applicable).
Enjoy Your New Slide Out Awning!
Congratulations! You’ve successfully measured and installed your RV slide out awning. Time to kick back, relax, and enjoy the shade (and the peace of mind knowing your slide out is protected).
