Understanding different tint percentages is crucial when considering window tint for your car. The percentage refers to the amount of visible light that passes through the film, known as Visible Light Transmission (VLT). The lower the percentage, the darker the tint. Choosing the right window tint percentage can impact visibility, privacy, and compliance with state regulations.


In this window tint guide, we’ll explore different car window tint levels, their benefits, and how to choose the right tint percentage for your needs.

Types of window tint

There are several types of window tint, each offering different benefits:

  • Dyed window tint – A cost-effective option that provides a darker appearance and reduces glare but offers minimal heat rejection.
  • Metalized window tint – Uses tiny metallic particles to reflect heat and UV rays while adding strength to the windows. However, it may interfere with electronic signals.
  • Carbon window tint – Offers excellent UV protection and heat reduction without interfering with signals. It provides a matte finish and is highly durable.
  • Ceramic window tint – The highest-quality tint available, providing superior heat rejection, UV protection, and glare reduction without affecting visibility or electronic signals.

Understanding window tint darkness levels

Selecting the right tint percentage depends on your needs and local laws.

Window tint percentages range from 5% (very dark) to 70% (very light). Here’s a breakdown of common car window tint levels and their characteristics:

  • 5% tint (limo tint) – This is the darkest option, allowing only 5% of light to pass through. It offers maximum privacy but can be difficult to see through at night. This level is often used on limousines and may not be legal for front windows in many states.
  • 20% tint – A popular choice for drivers who want privacy and heat reduction without complete darkness. It still provides a sleek look while maintaining some visibility from inside the car.
  • 35% tint – This level strikes a balance between aesthetics and functionality. It blocks a significant amount of sunlight while allowing for better visibility compared to darker tints.
  • 50% tint – Ideal for those who want UV protection and heat reduction without making the windows too dark. It allows more visibility while still providing a stylish appearance.
  • 70% tint – The lightest tint option, often used to reduce glare and UV exposure without significantly altering the look of the car’s windows.

Best window tint percentage for cars

The best window tint percentage for cars depends on factors like personal preference, state regulations, and functional needs. Here are some key considerations:

  • Aesthetic appeal – Darker tints, such as 20% or 35%, offer a sleek and modern appearance while still being practical.
  • Visibility and safety – If you often drive at night, a lighter tint like 35% or 50% is recommended to ensure clear visibility.
  • Privacy – If privacy is a top priority, 5% or 20% tint levels are ideal.
  • Heat and UV protection – Even lighter tints, such as 50% and 70%, can provide excellent UV protection and heat reduction.

Car tinting regulations: What you need to know

Car tinting regulations vary by state and country. Before selecting a window tint percentage, it’s essential to check local laws to avoid fines or legal issues. Many states have restrictions on how dark front windows can be, while rear and back windows often have more lenient rules.


In Cornelius, NC, window tinting laws are as follows:

  • Front-side windows – Must allow at least 35% of light to pass through.
  • Rear side and back windows – Must allow at least 35% of light to pass through.
  • Windshield tinting – Non-reflective tint is allowed on the top five inches of the windshield.

Always check with local authorities or a professional installer like Champion Window Tinting to ensure compliance with car tinting regulations.
