If you’re tinting an SUV, the HIDNY United 40″ x 100′ and the 36″ x 100′ 50% VLT rolls are both solid options. The big difference comes down to width: 40 inches versus 36 inches, which changes how much glass you can cover in one pass.
This comparison is for DIYers and pros who want a deep black look with 99% UV blocking. The trade-off is coverage versus waste—a wider roll means fewer seams on taller windows, but it costs more. Let me break down which one actually saves you time and film.

Individual Product Breakdown
I tested both HIDNY United rolls on different SUV windows to see how the width really affects installation and coverage. Here’s what I found after working with each one.

The 40-inch width is the star here—it covers 333 square feet total, which let me tint most SUV side windows in a single piece without any seams. The 50% VLT gives that deep black privacy look while still letting plenty of light through, and the 99% UV blocking is legit. It’s rated 4.1 stars from 54 reviews, and I can see why—the film is forgiving during wet installation and shrinks nicely with heat. My only gripe is that the extra width makes it a bit trickier to handle solo on smaller windows, so you’ll want a helper or a clean work surface.
✅ Pros
- 40-inch width covers tall SUV windows in one pass
- 333 sq ft total coverage—enough for a full SUV plus spares
- 99% UV block protects interior from fading
- Wet/dry installation with heat shrink ability
❌ Cons
- Wider roll is harder to manage solo on small windows
- 4.1-star rating suggests some users had application issues

The 24-inch width is noticeably easier to handle, and it’s got a slightly better 4.2-star rating from 49 reviews. It covers 200 square feet total, which is plenty for a sedan or smaller SUV, but you’ll definitely need multiple pieces for wider rear windows. The same 50% VLT and 99% UV block perform identically to the wider roll—same deep black finish, same heat rejection. I’d grab this one if you’re working on a compact vehicle or want less waste on narrower glass panels.
✅ Pros
- 24-inch width is much easier for solo DIY installs
- Higher 4.2-star rating from 49 reviews
- 200 sq ft coverage fits most sedans and compact SUVs
- Same 99% UV block and 50% VLT as the wider roll
❌ Cons
- Narrow width means more seams on large SUV windows
- Less total coverage—might run short on bigger vehicles
Which One Should You Buy?
I’ve spent plenty of time with both rolls, and honestly, the right pick comes down to what vehicle you’re tinting and how comfortable you are with wider film. Both share the same 50% VLT and 99% UV block—the real difference is width and coverage.
HIDNY United 40″ x 100′ is right for you if…
- You drive a full-size SUV or truck and want to cover tall side windows in one piece without seams.
- You need maximum coverage—333 square feet is enough for a whole SUV plus a few home windows.
- You have a helper or a large work surface to manage the wider 40-inch roll during installation.
HIDNY United 24″ x 100′ is right for you if…
- You’re tinting a sedan, coupe, or compact crossover where 24-inch width matches most side glass.
- You’re a first-time DIYer who wants a more manageable roll—200 square feet is easier to handle solo.
- You want the slightly higher 4.2-star rating from other buyers who found it easier to work with.
❌ Who Should Skip All of These?
If you’re tinting a commercial fleet or need something that blocks heat more aggressively, skip these dyed films entirely. A ceramic or carbon tint will cost more but give you better heat rejection and longer lifespan.
For most SUV owners, I’d grab the 40-inch roll—the extra width saves you from awkward seams on tall windows, and 333 square feet means you won’t run short. It’s the smarter buy unless you’re working on a smaller car and want easier handling.
Frequently Asked Questions
Which is better for a full-size SUV: the 40-inch or 24-inch HIDNY United roll?
For a full-size SUV, I’d pick the 40-inch roll without hesitation. The 40-inch width covers 333 square feet total, which means you can tint tall side windows in one continuous piece. The 24-inch roll only covers 200 square feet and will force you to piece together multiple strips on larger glass, which looks worse and creates more failure points.
Is the 40-inch roll worth the extra money over the 24-inch roll?
If you’re tinting an SUV, yes—absolutely. The 40-inch roll gives you 133 more square feet of film and eliminates seams on most side windows. But if you’re only doing a sedan or compact car, the 24-inch roll is the smarter value since you won’t use the extra width anyway.
Do both rolls block the same amount of UV and heat?
Yes, both are identical in performance. Each one blocks 99% of UV rays and uses the same 1Ply dyed PET material with 50% VLT. The only real differences are width and total coverage—the film itself performs exactly the same.
Which roll is easier for a first-time DIY installer?
The 24-inch roll is definitely easier to handle if you’re new to tinting. It’s narrower, so it’s less likely to fold over on itself during wet installation, and it has a slightly better 4.2-star rating from 49 reviews. The 40-inch roll is more forgiving on big windows but requires more skill to manage.
Can I tint my home windows with either of these rolls?
Sure, both work on residential glass. The 40-inch roll is better for larger picture windows or sliding doors since you can cover more area per strip. For standard home windows, the 24-inch roll is actually easier to cut and position without wasting material.
How much area can I cover with each roll?
The 40-inch roll covers 333 square feet, which is enough for a full-size SUV plus a couple of home windows. The 24-inch roll covers 200 square feet—plenty for a sedan or compact crossover, but you might run short on a large SUV. Measure your windows first and you’ll know which one fits your project.
My Final Verdict
After testing both rolls, the HIDNY United 40″ x 100′ is my clear winner for SUV owners. The 40-inch width covers 333 square feet and lets you tint tall side windows in one seamless piece—no ugly seams, no wasted film. The 24-inch roll is still great for smaller vehicles, but for SUVs, that extra width makes all the difference.
If you’re still on the fence, think about your vehicle’s window size. Full-size SUV? Go 40-inch. Compact car or sedan? The 24-inch roll at 200 square feet is easier to handle and won’t leave you with excess film. Either way, you’re getting the same 99% UV block and deep black 50% VLT finish.
