Window Tint Percentages Explained

Window tint isn’t just about looks—it plays a big role in comfort, UV protection, interior preservation, and even safety. But if you’ve ever shopped for tint, you’ve probably heard terms like “5%”, “20%”, or “70%” thrown around and wondered what they actually mean.

At Tailored Garage, we break down the numbers and laws so you can make an informed decision that matches your style and stays street legal.

What Does Window Tint Percentage Mean?

The percentage in window tint refers to Visible Light Transmission (VLT)—how much visible light the film allows to pass through the glass.

For example:

  • 5% VLT means only 5% of light passes through (very dark, also called “limo tint”)

  • 35% VLT allows 35% of visible light through (medium tint)

  • 70% VLT allows 70% of light through (very light tint)

Lower % = darker tint. Higher % = lighter tint.

This percentage affects how much visibility you have looking out, how much outsiders can see in, and how much heat and UV protection you’ll get.

Common Tint Percentages & Their Uses…

5% – Limo Tint

  • Very dark, used for privacy

  • Illegal on front windows in most states

  • Often used on rear windows or commercial vehicles

  • Low visibility at night

15% – Dark Privacy Tint

  • Offers serious privacy

  • Great heat rejection and glare reduction

  • Popular for rear windows

  • Still illegal on front windows in WA

20% – Factory Match

  • Common match for factory rear privacy glass

  • Looks clean and cohesive when paired with rear factory tint

  • Still too dark for front windows in WA

35% – Legal Limit in Washington (Front Side Windows)

  • Offers noticeable shading while maintaining good visibility

  • Legal on front driver and passenger windows

  • A great balance of style and functionality

50% – Subtle, Legal, and Clean

  • Lightly tinted

  • Provides moderate heat and UV rejection

  • Legal on all windows in Washington

  • Ideal for clients who want a cleaner, OEM-style look

70% – Ceramic Performance with Almost No Tint Look

  • Very light—nearly invisible

  • Often used in ceramic IR films where performance > darkness

  • Great for windshields (where legal)

  • High-end cars often use this for heat and UV without changing aesthetics

What’s Legal in Washington State?

Washington has specific window tint laws you’ll want to follow:

  • Front side windows: Must allow at least 24% VLT

  • Rear side and back windows: Any darkness allowed

  • Windshield: No tint allowed, except for the top 6 inches (AS-1 line)

Medical exemptions may apply in special cases but require a state permit.

Disclaimer: Always check current state regulations or ask us directly—we stay up-to-date so you don’t have to worry.

Why Ceramic Tint Is the Best Choice…

If you're looking for performance, not just looks, ceramic window tint is unmatched. It blocks:

  • 99% of UV rays

  • Up to 80% of infrared heat

  • Without going too dark or reflective

You can get the comfort and protection of a darker tint without actually making the glass look blacked out. That’s why we recommend ceramic tint to most of our clients, especially in luxury and exotic vehicles.

Front Match Tinting: Completing the Factory Look…

If your car came with factory rear privacy glass (typically around 20%), we can apply a matching film to your front side windows—usually 35% to stay legal and visually balanced.

We also offer options to ceramic tint your windshield with ultra-light 70% film for heat rejection without darkening the glass.
