Window tint comparison: 20% vs 35%, 15% vs 20%, 5% vs 20% side by side

A lower percentage is darker tint. The number is how much visible light the film lets through: 20% film lets through 20% of the light and 35% film lets through 35%, so 20% lets in about 43% less light than 35%. Below, each pair is the driver’s seat of the same 3D Tesla Model Y in daylight, with one film on every side and rear window.

“Less light” is 1 − darker ÷ lighter, rounded to a whole percent. The factory glass multiplies both films by the same amount, so the darker film lets in the same share less on the car. Measured by an owner with a calibrated meter (±2%) in August 2024 Cybertruck Owners Club. Tesla doesn’t publish these figures.

20% vs 35% tint

20% film lets through 20% of the visible light and 35% film lets through 35%, so 20% is darker and lets in about 43% less light. On the Cybertruck’s front door glass (72%), 35% film leaves 25.2% getting through and 20% leaves 14.4%. On one Cybertruck owners’ forum page, owners reported both 20% and 35% on their front side windows Cybertruck Owners Club, and one owner’s thread describes 20% on the front doors with 70% over the factory-dark rear glass Cybertruck Owners Club.

In the simulator: both on one car (35% on the front windows, 20% on the rear), or each one from the driver’s seat at night.

15% vs 20% tint

15% film lets through 15% of the visible light and 20% film lets through 20%, so 15% is darker and lets in about 25% less light. On the Cybertruck’s front door glass (72%), 20% film leaves 14.4% getting through and 15% leaves 10.8%. AAA calls a 15% VLT quite dark AAA. Owners on one Cybertruck forum page reported both 15% and 20% on their front side windows Cybertruck Owners Club.

5% vs 20% tint

5% film lets through 5% of the visible light and 20% film lets through 20%, so 5% is darker and lets in about 75% less light. On the Cybertruck’s front door glass (72%), 20% film leaves 14.4% getting through and 5% leaves 3.6%. 5% is the darkest film here: it lets through about one twentieth of the light. On one Cybertruck owners’ forum page, three owners reported 5% on their front side windows and one reported 20% Cybertruck Owners Club.

What about 30%?

30% film isn’t one of the shades on this page. It lets through 30% of the visible light, so it sits between 35% and 20%.

Does darker tint cost more?

Most shops charge the same for every shade of a film, so the shade rarely changes the price; the film type does. The tint and wrap cost guide shows what each film type costs.

Questions

Is 20% or 35% tint darker?

20% is darker. The number is how much visible light the film lets through: 20% film lets through 20% of the light and 35% film lets through 35%, so a lower number is a darker film.

How much darker is 20% than 35% tint?

20% film lets in about 43% less light than 35% film, because 20 is 43% less than 35. The glass under the film multiplies both by the same amount: on a Cybertruck’s front door glass, which lets through 72% from the factory as an owner measured it with a calibrated meter, 35% film leaves 25.2% and 20% film 14.4%.

Is 15% or 20% tint darker?

15% is darker. 15% film lets through 15% of the visible light and 20% film lets through 20%, so 15% lets in about 25% less light. AAA’s window tinting guide calls a 15% VLT quite dark.

What tint percentage is the darkest?

Of the films on this page, 5% is the darkest: it lets through about one twentieth of the visible light, and about 75% less light than 20% film. The lower the number, the darker the film.

Can I see 20% and 35% tint on a car before I buy?

Yes. The WrapColor window tint simulator can put 35% film on the front windows and 20% on the rear windows of a 3D car, and you can look from outside or from the driver’s seat, by day or at night. It’s an illustration, so in a shop also ask the installer to hold film samples against your own window.
