Window Tint Percentages Explained
Complete guide to window tint VLT percentages. Compare 5%, 20%, 35%, 50%, and 70% tint darkness to find the right level for your vehicle.
Understanding VLT (Visible Light Transmission)
VLT percentage measures how much visible light passes through your window tint film. The number represents the percentage of light that makes it through:
- 5% VLT = Only 5% of light passes through (very dark)
- 35% VLT = 35% of light passes through (medium)
- 70% VLT = 70% of light passes through (light)
Key Formula
Heat Blocked = 100% - VLT%
A 20% tint blocks approximately 80% of visible light

*70% ceramic tint can achieve excellent heat rejection despite low VLT
Ceramic Tint: The Game Changer
Ceramic window tint uses nano-ceramic particles to reject heat without darkening the film. This means you can achieve excellent heat rejection at legal VLT percentages.
Standard Dyed Tint
- Heat rejection tied to darkness
- Blocks heat with color/dye
- Fades over time
- More affordable option
Ceramic Tint
- High heat rejection at any VLT
- Blocks infrared (IR) rays
- No fading or discoloration
- Premium investment
Frequently Asked Questions
What does window tint percentage mean?
Window tint percentage refers to VLT (Visible Light Transmission) - the amount of light that passes through the tint. A 35% tint allows 35% of light through and blocks 65%. Lower percentages mean darker tint.
What is the best window tint percentage?
35% is the most popular choice because it's legal in most states for front side windows while still providing good privacy and heat rejection. For back windows, 20% or 5% offer more privacy where legal.
Is 5% tint legal?
5% tint (limo tint) is only legal for rear windows in most states. It's illegal on front side windows in all 50 states due to safety concerns with visibility.
What is the darkest legal tint?
The darkest legal tint varies by state and window position. Most states allow 20-35% on front side windows and any darkness on rear windows. Check your state's specific laws.
Can you see through 20% tint at night?
20% tint makes it difficult to see out at night, especially in unlit areas. While daytime visibility is adequate, night driving requires extra caution. This is why many states restrict dark tint on front windows.
Does darker tint block more heat?
Yes, darker tint generally blocks more visible light heat. However, ceramic tint at any percentage can reject more infrared heat than dyed film. A 70% ceramic tint may reject more heat than a 35% dyed tint.
