Best Window Tint Percentage: How to Choose the Right Shade
Not sure how dark to go with your window tint? This guide explains VLT percentages from 5% to 70% so you can pick the perfect shade for your vehicle.
Choosing the right window tint darkness is one of the first decisions you will make when getting your vehicle tinted. Tint darkness is measured in VLT — Visible Light Transmission — which tells you what percentage of light passes through the film. A lower number means a darker tint.
Understanding VLT Percentages
70% VLT: Barely noticeable from the outside. Blocks UV and some heat while maintaining a nearly factory appearance. Popular for windshields (where legal) and for drivers who want protection without visible change.
50% VLT: Mild tint that is noticeable up close but still lets in plenty of light. Good for drivers who want some heat reduction and privacy without going dark.
35% VLT: The "sweet spot" for many drivers. Noticeably darker from the outside, reduces glare significantly, and provides solid heat rejection with ceramic film. This is the legal limit for front windows in Kentucky.
30% VLT: The Indiana legal limit for front side windows. Provides a clean, dark look while staying compliant with state law.
20% VLT: A popular choice for rear windows. Provides strong privacy and noticeable darkening. Cannot be used on front side windows in Indiana or Kentucky.
5% VLT (Limo Tint): Maximum privacy. Nearly impossible to see inside during daytime. Legal only on rear windows in Indiana. Creates a striking blacked-out appearance.
What We Recommend
For Indiana-registered vehicles, we recommend 30% VLT on the front side windows (the legal maximum) and 20% or 5% on the rear windows depending on how much privacy you want. This combination gives you a balanced look with legal compliance.
For Kentucky vehicles, we recommend 35% on the fronts and 18% or darker on the rears.
Does Tint Percentage Affect Heat Rejection?
The darkness of the tint does not directly determine heat rejection. Heat rejection depends on the film technology:
Dyed film (Autobahn Black Line): Darker tints absorb more solar energy but also radiate some of that heat inward. Heat rejection is moderate regardless of shade.
Ceramic film (Black Ceramic or i3): Blocks infrared heat using nano-ceramic particles. A lighter ceramic film (50% VLT) can reject more heat than a dark dyed film (5% VLT). Ceramic technology separates darkness from performance.
The Bottom Line
Choose your tint darkness based on how you want your vehicle to look and how much privacy you need. Choose your film type (dyed vs. ceramic) based on how much heat and UV protection you want.
