How to Choose the Right Size Privacy Curtains for Your Vehicle

My first attempt at car camping privacy involved a $10 roll of black plastic sheeting and some questionable duct tape. It looked like a crime scene in my Honda CR-V at a state park in Ohio. The problem wasn't just aesthetics; it was realizing I had zero clue about how to actually size window coverings for a vehicle that wasn't a van.

I learned the hard way that not all windows are created equal, and neither are your privacy needs.

You see, what works for a sedan's back window is a total disaster for a crossover's side windows. I ended up with gaps big enough for a squirrel to parachute through. This whole privacy curtain thing can feel like rocket science when you're staring at a bunch of confusing measurements and fabric types.

But trust me, it's way simpler than you think if you just focus on what actually matters.

The Core Answer

The real move for privacy curtains, and honestly for anything in car camping, is to stop overthinking and start measuring. Forget the fancy jargon; you just need to know the dimensions of the glass you want to cover. My first rookie mistake was buying generic sunshades that were supposed to fit 'most cars.' They didn't fit anything well.

The honest version: grab a tape measure. For each window, measure the width and height of the actual glass. Write it down. This is game-time information. Don't measure the entire door panel or the trim - just the glass itself.

For example, my old Subaru Forester had rear windows that measured roughly 30 inches wide by 20 inches tall. That's the size you need to look for. If you're buying pre-made shades, they usually list dimensions. If they don't, run.

If you're going the DIY route with fabric, like some folks on r/vandwellers suggest with foam board, you'll need those exact numbers to cut your material.

What nobody tells beginners is that a slight overlap or a snug fit makes a massive difference. For windows that meet in the middle, like a windshield or a rear hatch, you might need two pieces. Or, you can get a single, larger piece that you fold.

My $50 version of custom-fit shades involved meticulously measuring each window on my current SUV and then ordering from a company that let me input those exact measurements. It was worth every penny because I could actually sleep without seeing headlights.

Think about how the curtain attaches too. Some use static cling, others have suction cups, and some are designed to tuck into the window frame. Whatever method, make sure it accounts for the size you measured. A curtain that's too big will sag, and one that's too small leaves embarrassing gaps.

The goal is a clean look and zero light leakage. I learned this at a campground in Virginia where my poorly fitted curtains practically advertised I was sleeping in my car. The fix was simply getting curtains that matched my glass dimensions precisely.

For larger areas like dividing the cab from the back, you might need a wider measurement, often listed as interior width. Some sources suggest looking for curtains up to 55 inches wide for this purpose. It's all about matching the product to the space you're trying to cover.

The $12 fleece liner I bought for my sleeping bag was a game-changer because it fit. The same logic applies here: the right size makes all the difference between a comfortable camping setup and a frustrating mess.

So, measure twice, buy once. It's the simplest advice, but it's the one that will save you the most headaches and embarrassment.

Why This Matters for Your Setup

Stealth Camping: If you're trying to sleep somewhere that isn't an official campground, like a Walmart parking lot or a quiet street, precise window coverings are non-negotiable. My first time trying this in a city, my back window had a gap big enough to see my sleeping bag. I felt like I was on display for the entire block.

* Light Blocking: Even in campgrounds, you don't want to wake up at 5 AM because the sun is blasting through your windshield. Blackout curtains are designed for this, but they only work if they actually cover the glass. I learned this the hard way at a KOA in Pennsylvania; the sunrise was my alarm clock.

* Temperature Control: While not their primary job, good-fitting curtains do help a bit with insulation. They can block some of the intense heat from baking your car's interior on a sunny day. My friend's cheap, ill-fitting shades in Arizona barely made a dent in the heat.

* Privacy from Prying Eyes: This is the obvious one. Whether it's other campers, curious locals, or just random folks walking by, you want to feel secure. I once had someone peer into my car at a scenic overlook, and I instantly regretted not having better window coverage.

* Keeping Valuables Hidden: If you're leaving gear in your car, good privacy curtains prevent smash-and-grab thieves from seeing tempting electronics or camping equipment. It's like drawing the blinds at home, but for your car.

Making the Right Choice

Measure Your Glass: I cannot stress this enough. Get your tape measure out and get the exact width and height of each window you want to cover. Don't guess.

* Consider the Material: Blackout is usually best for sleeping, but some people prefer mesh for daytime driving privacy while still allowing some visibility. The material also affects how well it blocks heat.

* Attachment Method Matters: How the curtain sticks or tucks into the window is crucial for a good seal. Suction cups can fail, especially in temperature swings. Look for designs that use the window frame or magnetic seals for a more reliable fit.

* Don't Be Afraid of DIY (If You're Handy): If you're crafty, cutting your own foam board or fabric to size can be cheaper. I saw some slick foam board setups on Reddit that looked like they belonged there.

* Invest in a Good Fit: My initial $20 set of generic shades was a waste of money. Spending a bit more, maybe $50-$100, for custom-sized or high-quality, well-fitting curtains is the real move for comfort and peace of mind.

* Check Reviews: Before buying, see what other car campers are saying about specific products. Real-world experience from others is gold.
