Window tint in Illinois
Illinois uses a combined net VLT measurement which affects how dark you can actually go, but the 35% front side limit is still in the lenient range nationally. Sedan rear windows are unrestricted, and SUVs get even more flexibility across all rear glass. Local rules can vary by county so it's worth double-checking with your installer before you commit.

Frequently Asked Questions
What is the legal window tint in Illinois?
Front side windows need a minimum of 35% VLT. Back side windows require 35% VLT, and the rear window requires any darkness. Combined NET VLT measurement. 5% tolerance. Verify current county/local requirements as rules vary.
How much is a tint ticket in Illinois?

What is combined VLT and why does it matter?
Your car's factory glass already blocks some light (usually around 70-80% VLT). When you add tint film, the combined VLT is lower than the film alone. For example, 35% film on 75% factory glass gives you about 26% combined VLT. The calculator above does this math for you.
Can I preview tint on my car before installing?
Yes. Car Editor's AI tint simulator lets you upload a photo of your car and see any tint level applied to it in seconds. You can try different VLT percentages on your actual vehicle before committing.
