What Window Tint Percentage Should You Get in California?
In California, the law dictates that the front side windows must allow at least 70% of light in, while rear windows can be as dark as you want. For Riverside drivers looking for the perfect balance of heat rejection, privacy, and legal compliance, a 35% or 50% ceramic tint on the rear windows is often the sweet spot.
What Do Tint Percentages Actually Mean?
Tint is measured by VLT, or Visible Light Transmission. The percentage tells you how much light the film allows to pass through into the cabin.
- 70% VLT: Very light, almost clear. Required by law for front side windows in California.
- 50% VLT: A light tint that cuts glare but remains easy to see through at night.
- 35% VLT: A medium tint that offers a good balance of privacy and visibility.
- 20% VLT: Dark tint, making it difficult to see inside the vehicle from a distance.
- 5% VLT: "Limo tint." Very dark, offering maximum privacy but making night driving difficult.
The Best Tint Percentage for Heat Rejection in Riverside
It's a common misconception that darker tint equals cooler temperatures. The truth is, heat rejection is about the material, not the shade. A high-quality 70% ceramic film will reject significantly more heat than a dark 5% dyed film. In Riverside, where the sun beats down relentlessly, upgrading to a ceramic window tint is far more important for staying cool than picking the darkest shade.
The Best Tint Percentage for Privacy Without Going Too Dark
If your main goal is privacy—perhaps you keep tools or valuables in the back seat—20% or 35% VLT on the rear windows is ideal. It obscures the view into the cabin from the outside without making it dangerously difficult for you to see out through the rearview mirror at night.
Front Windows vs. Rear Windows — Different Percentages, Different Rules
California law is strict:
- Front Windshield: Only the top 4 inches can be tinted.
- Front Side Windows: Must have a combined light transmission (glass + film) of 70% or more.
- Rear Side Windows and Rear Window: Any darkness can be used.
Because of this, most drivers opt for a "staggered" setup—lighter film on the front doors to stay legal, and darker film on the back half of the car.
What Percentage Do Most Riverside Drivers Choose?
At C&D's Tint Lab, the most common request we see is a 70% or 50% ceramic film on the front side windows (to prioritize heat rejection while staying close to legal limits) combined with a 20% or 35% tint on the rear windows for privacy and aesthetics. Many clients also choose to add ceramic coating to the exterior for a complete vehicle protection package.
