About Window Tinting
Window tinting refers to the process of applying a thin laminate film to a vehicle's windows to reduce the amount of visible light, heat, and UV radiation that passes through.
Benefits of Window Tinting:
- UV Protection: Blocks up to 99% of harmful UV rays
- Heat Reduction: Keeps your car cooler in summer
- Glare Reduction: Improves visibility and reduces eye strain
- Privacy: Provides additional privacy for passengers
- Interior Protection: Prevents fading and cracking of upholstery
- Safety: Helps hold glass together in case of breakage
Tint Percentage Meaning:
Tint percentage refers to the amount of visible light that can pass through the window. For example:
- 5% tint: Allows only 5% of light in (very dark)
- 20% tint: Allows 20% of light in (medium dark)
- 35% tint: Allows 35% of light in (light to medium)
- 50% tint: Allows 50% of light in (light)
- 70% tint: Allows 70% of light in (very light)
Window Tint Laws by State
Tint laws vary significantly by state. Here's a general overview of common regulations:
Front Side Windows:
- Most states allow between 35-50% VLT (Visible Light Transmission)
- Some states like California, New York, and Pennsylvania require 70% VLT or more
- A few states like Michigan and New Jersey prohibit any tint on front side windows
Rear Side Windows:
- Most states allow darker tints (20-35% VLT) for rear side windows
- Some states allow any darkness for rear side windows
Rear Window:
- Generally follows the same rules as rear side windows
- Some states require dual side mirrors if rear window is tinted
Windshield:
- Most states only allow non-reflective tint on the top 4-6 inches
- A few states allow light tint (70% VLT or higher) on the entire windshield
Note: Laws change frequently. Always check with your local DMV or law enforcement for the most current regulations in your area.
Tips for Choosing Window Tint
- Consider your primary reason for tinting (privacy, heat reduction, UV protection)
- Check your local laws before selecting tint darkness
- Higher quality films provide better heat rejection regardless of darkness
- Ceramic tints offer the best heat rejection without being overly dark
- Professional installation is recommended for best results
- Ask about warranties - quality films often come with lifetime warranties

Do you want to increase your vehicle’s privacy, reduce glare, or protect your interior from UV rays? The tint percentage calculator is an essential tool to help you completely determine the right window tint percentage for you. Whether you are a car enthusiast, a homeowner, or a businessperson, understanding tint percentages can be very important to you.
What is a Tint Percentage Calculator?
The Tint Percentage Calculator is an online tool that calculates the Visible Light Transmission (VLT) percentage of a window tint. The VLT percentage indicates how much light passes through a tinted window. For example, a 20% VLT tint allows 20% of visible light to pass through, while blocking the remaining 80%. This tool helps you to:
- Calculate the combined VLT when combining multiple tint layers.
- Ensure compliance with local window tint laws.
- Choosing the right tint level for aesthetics, privacy, or heat reduction.
Our free Tint Percentage Calculator is user-friendly, accurate, and perfect for making tinting decisions.
Why use the Tint Percentage Calculator?
Window tinting is not just about adding a stylish touch to your vehicle, it’s also about safety, vehicle performance, and legalities. Here’s why a tint percentage calculator is important:
- Being compliant: Every state and country has its own tinting laws. This calculator lets you know if your chosen tint is legal so you can avoid fines or legal hassles.
- Light and heat control: Whether you want a dark tint for more privacy or a light one for better visibility, this tool helps you find the right balance.
- Accurate calculation of multiple tint layers: If you’re applying another tint over the factory tint, this calculator will tell you how much VLT (Visible Light Transmission) the two will have combined to get the results you want.
- Save time and money: Avoid getting the wrong tint and then removing it again and again. Find out the correct percentage before installation, so that you do not face any problems later.
How does the tint percentage calculator work?
Basically, our tint percentage calculator uses a very simple formula to calculate how much light will be transmitted if you apply multiple tint layers. The formula is as follows:
Total VLT = VLT1 × VLT2 × … × VLTn
Here:
VLT1, VLT2, etc. are the “visible light transmission” (VLT) percentages of each tint layer, expressed as decimals (e.g. 50% = 0.5).
The result will tell you how much light will pass through the glass after all the tint layers have been applied.
Let’s take an example:
Suppose your car windows already have a factory tint of 70% VLT (i.e. 0.7). Now you apply an additional tint of 20% VLT (i.e. 0.2). So the calculation will be something like this:
Total VLT = 0.7 × 0.2 = 0.14 i.e. 14%
This means that after applying both the tints, only 14% of the light will be able to enter the window, due to which the window will look very dark.
How to use our Tint Percentage Calculator
It’s simple, just follow these steps:
- Enter the VLT of the first layer: If your window already has a tint applied (like a factory tint on a car), enter its VLT percentage here.
- Add more layers: If you’re applying more than one tint, enter the VLT of each layer separately.
- Get instant results: The calculator will show you the overall VLT percentage so you can see if the tint is right for your needs and local regulations.
- Check local laws: Make sure your tint is legal with our built-in guide (for select areas).

Frequently Asked Questions
VLT stands for Visible Light Transmission, which indicates the percentage of visible light that passes through a tinted window. A lower VLT means a darker tint.
Yes, our calculator uses the standard VLT formula and provides accurate results based on the input percentages.
Absolutely yes! This calculator works for any tinted glass, including car windows, home windows, or commercial buildings.
Check your local tint laws, which specify the allowed VLT percentages for different windows. Our calculator can help verify compliance.
Adding tint layers reduces the overall VLT. Our calculator gives a combined result by multiplying the VLT percentage of each layer.
