What Window Tint Percentage Should You Choose?

5%? 20%? 35%?

Most people pick based on what “looks good”—but in Arizona, that’s not the smartest way to decide.

Tint percentage affects:
– how much heat your car absorbs
– how well you can see at night
– how legal your vehicle is on the road

And choosing the wrong one can lead to poor visibility, discomfort, or even getting pulled over.

In this guide, we’ll break down what tint percentages actually mean, how they perform in Arizona heat, and how to choose the right one for your vehicle.

What Do Window Tint Percentages Actually Mean?

Window tint percentages don’t refer to how much light is blocked—they refer to how much light is allowed through.

This is called Visible Light Transmission (VLT). The lower the percentage, the darker the tint.

For example:

Tesla window with 5 percent window tint showing very dark, nearly opaque glass

5% tint
Very dark. Often called “limo tint.” Allows only 5% of light through.

Tesla window with 15 percent tint showing dark glass with slight visibility inside

20% tint
Dark, but still usable for most drivers. A popular choice for privacy.

Tesla window with 35 percent tint showing moderate visibility into the interior

35% tint
Moderate shade. Lets in more light while still reducing glare and heat.

Tesla window with 50 percent tint showing light shading and high visibility

50%+ tint
Light tint. Primarily used for heat and UV protection without changing appearance much.

So when you’re choosing a tint percentage, you’re really choosing how dark you want your windows—and how much visibility and heat reduction you need.

What Different Tint Percentages Look Like

Understanding percentages is one thing—seeing how they actually perform is what makes the decision easier.

Here’s how the most common tint levels typically feel:

Tint % Description Best for: Keep in mind:
5% Tint (Limo Tint)

20% Tint A popular middle ground between privacy and usability. • Drivers who want a darker appearance
• Increased privacy without going fully blacked out
• Reduced visibility at night compared to lighter tints
• Often used on rear windows with lighter front tint
35% Tint One of the most balanced options. • Daily drivers
• Good visibility while still reducing glare and heat
• Less privacy than darker options
• Often closer to legal limits for front windows
50%+ Tint Light tint focused more on performance than appearance. • Windshields (where allowed)
• Drivers who want heat rejection without a dark look
• Minimal privacy
• More about comfort than style

Keep in mind that laws can vary slightly depending on your vehicle and how tint is applied.

Choosing the right percentage isn’t just about looks—it’s about staying compliant and avoiding tickets.

 

Which Window Tint Percentage Should You Choose?

The right tint percentage depends on how you use your vehicle, how much visibility you want, and how important heat rejection is for you.

Here’s a simple way to decide:

• You want maximum privacy
• You prefer a bold, blackout look
• It’s being used on rear windows

• You want a balance between visibility and performance
• You drive frequently at night
• You want to stay closer to legal limits for front windows

• You want a darker appearance without going fully blacked out
• You’re looking for more privacy
• You don’t mind slightly reduced night visibility

• You want heat and UV protection without a darker look
• You’re tinting your windshield (within legal limits)
• You prioritize visibility over privacy

For most drivers in Arizona, a combination works best—lighter tint on the front windows and darker tint on the rea

Frequently Asked Questions About Window Tint Percentage

35% for front windows and 20% for rear windows is a common combination, balancing visibility, comfort, and legality.

For most drivers, yes—especially at night. It’s typically better suited for rear windows rather than full vehicle coverage.

Not always. Film type (like ceramic vs standard) has a bigger impact on heat rejection than darkness alone.

No. Arizona law requires front side windows to allow more than 33% of light through.

Lighter ceramic films can outperform darker standard tints. The type of film matters more than just the percentage.
