How Is Window Tint Measured?

There are many misconceptions about how window tint is measured, including how it affects the visibility of your car, the legality of rvinyl films, and the effect on the safety of your passengers. If you’d like to learn more about these topics, keep reading! The article below outlines some of the most common misconceptions about car window tint. This information will help you make an informed decision and protect yourself from any legal issues that may arise.

How Is Window Tint Measured?

Visible Light Transmission (VLT)

When measuring window tint, consider the end result, or Visible Light Transmission (VLT). In other words, if a glass window is 30 percent VLT, but has a tint of 15 percent, it will still be 20 percent VLT. This difference between the two values can be a factor of several hundred, making the actual VLT figure much higher than it is on paper. To make matters worse, the tint may be so dark that it doesn’t even block sunlight from reaching the inside.

The term VLT is the amount of visible light that passes through a lens. For example, a lens with 12% VLT allows only 12% of light to pass through, while one with 8% VLT blocks 88% of light. Similarly, the VLT of a window film determines how much heat, UV, and security it can provide. The higher the VLT, the more visible light it can filter, and the less heat it can absorb.

Car window tint percentages

Car window tint percentages are measured by VLT, or visible light transmission. If you want to get your car’s windows to be as dark as possible, the lower the VLT, the darker the tint will be. The VLT ranges from 5% to 70%. Factory-installed windows don’t let 100% of light through, so to get a proper tint level, you need to multiply the VLT of the new tint by 80%.

In addition to the percentage of the film, the tint’s quality is important, too. The percentages may not be accurate, and your car could look very dark if you put too much or too little tint. Also, if you buy the film yourself, you may get into legal trouble if it turns out to be too dark. To avoid any legal trouble, get your tint professionally installed. An experienced team will know exactly what to do, and will help you choose a tint percentage that suits your needs and your car.

Rvinyl films

It is important to know the right way to measure the tint level on your car windows. The Rvinyl films measure window tint precisely. You should choose the right percentage for your car window, as the law specifies a certain level. Moreover, it’s essential to understand the benefits of these films, which include protecting your skin from sunburn and ensuring that the car has a stylish look. Below are some of the benefits of window tints.

A good tint film is able to block the maximum amount of solar heat and visible light, while at the same time allowing some visible light to come through. Luminous efficiency, or LE, is determined by dividing the percentage of visible light that passes through the tint by the shading coefficient. For instance, a window tint with a 60 percent VLT and a.4 coefficient is 1.58 LE, while a film with a higher value is able to allow more visible light to pass through and less heat to escape.


When it comes to measuring window tint, many people make the mistake of measuring for darkness, not light. While there are no specific laws concerning window tint, most states have some rules regarding how dark the film should be. If you have a medical condition or have sensitive skin, you can get a darker film than what is allowed by the law. It is important to read the law carefully, though, because some states do not allow dark films.

The state of New York has made window tinting illegal for any tinting over 35% VLT. VLT stands for visible light transmission, and refers to the amount of light that passes through the tinting film. To determine how dark your tint is, simply multiply the VLT of your window film by that of your glass. The result is a percentage that is close to 64%. Remember that a very dark tint will interfere with night vision, so be sure to take this into consideration when choosing your film.
