What Do Window Tint Percentages Mean?

Window tint percentage refers to Visible Light Transmission (VLT) — the percentage of visible light that can pass through the glass and film combined.

• Lower percentage = darker tint (more privacy)
• Higher percentage = lighter tint (more subtle appearance)

For example, 5% tint allows only 5% of light through (very dark), while 50% tint allows 50% of light through (light smoke appearance).

What Does 5% Window Tint Look Like on a Car?

5% window tint, often called limo tint, looks almost black from the outside of a car. It offers maximum privacy, making the interior very difficult to see during daylight.

5% tint (limo tint): near-black appearance from the outside.

Best for

• Maximum privacy
• Rear windows, vans, and boot glass
• Show cars or vehicles carrying tools/equipment

Things to know

• Not suitable for front windows in the UK
• Night-time visibility from inside is reduced compared to lighter tints

Compared to 20% tint, 5% tint is significantly darker and offers far more privacy, especially on rear windows and vans.

What Does 20% Window Tint Look Like on a Car?

20% window tint gives a dark, sporty look with strong privacy. It’s one of the most popular choices for rear windows because it noticeably darkens the glass without going fully black.

20% tint: dark, sporty appearance with strong privacy.

Best for

• Rear passenger windows
• Drivers wanting privacy without full limo darkness
• Vans and SUVs

Things to know

• Typically too dark for UK front windows
• A great balance between appearance and privacy for rear glass

What Does 35% Window Tint Look Like on a Car?

35% window tint looks like a medium tint with a clean, factory-style finish. It reduces glare and bright sunlight while keeping visibility strong in most conditions.

35% tint: a medium shade often chosen for a factory-style look.

Best for

• Drivers who want a subtle OEM look
• Reducing glare while keeping good night visibility
• Comfort-focused tinting rather than maximum privacy

Things to know

• Privacy is moderate (less than 20% and 5%)
• Often chosen for daily driving comfort

What Does 50% Window Tint Look Like on a Car?

50% window tint is a light smoke shade. It’s subtle from the outside but still helps with glare reduction and UV protection.

50% tint: subtle light smoke appearance with comfortable visibility.

Best for

• Glare reduction and comfort
• Customers wanting minimal visual change
• Day & night visibility

Things to know

• Least privacy-focused option
• Ideal if you want a gentle tint without a dark look

What Does 70% Window Tint Look Like on a Car?

70% window tint is a very light tint that looks almost clear from the outside. It’s designed to offer subtle glare reduction and UV protection while keeping the glass looking close to factory standard.

70% tint: very light, near-clear appearance with minimal visual change.

Best for

• Front side windows where legality is a concern
• Drivers wanting minimal visual change
• Reducing glare without darkening the glass

Things to know

• Offers very little privacy
• Often chosen to stay within UK legal limits on front windows
• Appearance is subtle compared to 50% and darker tints

Compared to 50% tint, 70% is noticeably lighter and closer to clear glass, making it a popular choice for drivers who want protection without a tinted look.

Which Tint Percentage Is Best for You?

The “best” tint depends on your goals. Use the quick guide below:

UK Window Tint Law (Important)

In the UK, front windscreens must allow at least 75% of light through and front side windows 70%. Darker tints are permitted on rear windows.

Because most cars already have factory-tinted glass, adding film may reduce light transmission further.

Does Tint Percentage Affect Visibility?

Yes. Darker tints reduce incoming light. This can improve comfort in bright sunlight and increase privacy, but very dark shades can reduce night-time visibility.

• Best balance for daily driving: 20% or 35%
• Best for privacy on rear windows: 5% or 20%

Frequently Asked Questions

Does darker tint mean more heat rejection?

Not always. Heat rejection depends on the type and quality of the film as well as the tint shade.

Can I mix tint percentages on my car?

Yes. Many drivers choose a lighter shade on the front (where legal) and a darker shade on the rear for privacy.

What does 5% tint look like during the day vs at night?

In daylight, 5% tint looks near-black from outside and provides maximum privacy. At night, it’s still very dark but interior lights and headlights can make silhouettes more visible from certain angles. From the driver’s perspective, visibility through 5% tint is noticeably reduced in low light.

Will tint fade or bubble over time?

High-quality automotive film is designed to resist fading and bubbling when installed correctly. Proper cleaning, correct installation, and allowing time for curing all help the tint last longer.
