I’m looking at two nearly identical rolls of window tint from HIDNY United: the 24″ x 100′ and the 20″ x 100′. Both are 5% VLT 1Ply Dyed PET film that blocks 99% of UV rays, so the real choice comes down to width and coverage.

This comparison is for DIY installers and car owners who want maximum privacy without paying a pro. The 24-inch roll gives you more width per strip, while the 20-inch saves a bit of cash — I’ll break down which one actually fits your windows better.

This is the roll I’d grab for most sedans and coupes. The 24-inch width gives you enough material to cover most side windows in a single strip without splicing, which makes the wet/dry installation process noticeably smoother. It covers 166.67 square feet, and at 5% VLT you get that deep black privacy look that’s hard to beat. The only downside is that it costs a bit more per square foot than the 20-inch roll, so if you’re on a tight budget, that’s worth considering.

✅ Pros

  • Wider 24″ strips reduce cutting waste on side windows
  • Blocks 99% of UV rays to protect your interior
  • Covers 166.67 sq ft — plenty for a full car
  • Easy wet/dry install with heat shrink ability

❌ Cons

  • Higher cost per square foot than the 20″ roll
  • 1-ply dyed film may not be as durable as ceramic options

This 20-inch roll is the budget pick, and it’s a solid one if you’re working on smaller windows or a compact car. It covers 167 square feet — actually a hair more than the 24-inch version — so you’re not losing any material for the money. The narrower width means you’ll need to be more careful with cutting on larger side windows, but for trucks and smaller SUVs it works just fine. The 5% VLT and 99% UV block are identical to the bigger roll, so you’re only giving up that extra width.

✅ Pros

  • Better value at a lower cost per square foot
  • Covers 167 sq ft — slightly more than the 24″ roll
  • Same 99% UV block and 5% VLT as the wider version
  • Great for compact cars, trucks, and home windows

❌ Cons

  • Narrower 20″ width requires more precise cutting on large windows
  • May need two strips for taller rear windows

Which One Should You Buy?

Honestly, both rolls will give you the same deep black 5% VLT look and 99% UV protection — the only real difference is the width and what you pay per square foot. Your choice comes down to the size of your windows and how much cutting you’re willing to do.

HIDNY United 24″ x 100′ is right for you if…

  • You drive a sedan or coupe with large side windows that need a single 24-inch strip without splicing.
  • You’re a DIY installer who wants an easier wet/dry application with fewer seams on bigger glass.
  • You prioritize convenience over saving a few bucks per square foot on your 166.67 sq ft roll.

HIDNY United 20″ x 100′ is right for you if…

  • You drive a compact car, truck, or SUV with smaller side windows that fit within a 20-inch width.
  • You’re on a tighter budget and want the lower cost per square foot on your 167 sq ft roll.
  • You’re tinting home windows or a van where narrower strips are actually easier to handle.

❌ Who Should Skip All of These?

If you’re tinting a windshield or large curved rear glass, skip these dyed PET rolls entirely — you’ll want a high-quality ceramic film that handles heat shrinking better and won’t fade as fast. These 1-ply dyed films are great for side windows, but they’re not built for the most demanding applications.

For most car owners doing a standard side-window job, I’d grab the 24-inch roll — the extra width saves you time and frustration during installation, and the slightly higher cost is worth it. If you’re on a strict budget or working on a compact vehicle, the 20-inch roll gets the job done for less.

Frequently Asked Questions

Which is better for a sedan — the 24-inch or 20-inch HIDNY tint roll?

For a sedan, I’d go with the 24-inch roll. Most sedan side windows measure over 20 inches in height, so the wider 24-inch film lets you cover them in a single strip without splicing. The 20-inch roll covers 167 square feet to the 24-inch’s 166.67, but you’ll waste more material cutting it to fit larger windows. The extra width on the 24-inch version makes installation noticeably less fiddly.

Is the 24-inch roll worth the extra cost over the 20-inch?

If you’re working on a standard car, yes — the 24-inch roll costs more per square foot, but the convenience of not piecing together multiple strips on tall windows is worth it. The 20-inch roll is a better value if you’re tinting smaller windows like those on a compact car, truck, or home. Both give you the same 5% VLT and 99% UV block, so the only real difference is width and price.

Do both rolls provide the same level of privacy and UV protection?

Yes, absolutely. Both are 5% VLT 1Ply dyed PET film that blocks 99% of UV rays, so you get the same deep black privacy look and interior protection from either roll. The 24-inch covers 166.67 square feet while the 20-inch covers 167 square feet — essentially identical coverage. The only difference is the width of each strip, not the film quality.

Which roll is better for a truck or SUV with large windows?

I’d pick the 24-inch roll for trucks and SUVs. Those vehicles often have tall side windows that exceed 20 inches, so the wider film reduces the number of seams you’ll need. The 20-inch roll works but requires more careful measuring and cutting on bigger glass. If you’re tinting a full-size SUV, the 24-inch width saves you time and potential mistakes.

Can I use these rolls for home windows too?

Yes, both are marketed for cars, trucks, SUVs, and home use. For residential windows, the 20-inch roll is often easier to handle because home panes are typically smaller and more rectangular. The 5% VLT is extremely dark though, so make sure you’re okay with near-blackout privacy before applying it indoors. Both rolls have the same wet/dry install method with heat shrink ability.

How much area does each roll actually cover?

The 24-inch roll covers 166.67 square feet, while the 20-inch roll covers 167 square feet — they’re nearly identical in total coverage. The real difference is that the 24-inch gives you wider strips, meaning fewer cuts and seams on large windows. For most cars, one 100-foot roll is enough for all side windows and sometimes the rear window too.

My Final Verdict

The HIDNY United 24″ x 100′ is my clear winner for most car owners. The extra 4 inches of width makes installation on standard side windows far easier, and you’re only paying a small premium per square foot for that convenience. Both rolls give you the same 5% VLT, 99% UV block, and nearly identical coverage (166.67 vs 167 sq ft), so the deciding factor is purely about fit and ease of use.

If you’re still on the fence, think about what vehicle you’re tinting. For sedans, coupes, or SUVs with tall windows, the 24-inch roll will save you headaches. If you’re on a strict budget or working on a compact car or home windows, the 20-inch roll gets the job done for less — just be ready for more precise cutting.
