You’ll multiply 75% x 20%, which gives you a final approximate tint of 15%, a very dark tint. To figure out how much light your factory tint and your window film will let in when combined, you’ll multiply their VLTs together and make it a percentage.įor example, let’s say your factory tint is 75% and you want to install a window film with a VLT of 20%. It’s also important to know how an aftermarket tint will affect the look of your ride. If not, your tint installer can use a tint meter to find the exact percentage. Some vehicle manufacturers provide this information in their literature. You don’t need to know your car’s exact VLT before getting an aftermarket tint, but it can help.

When you’re buying car window tint, another common mistake is to assume that you’re starting from scratch with your current windows. This makes for a dark and private car interior, where a VLT of 70% would let 70% of the sunlight through, leaving a much brighter space within your car. This means that using a window film with a VLT of 20% will allow only 20% of sunlight to pass through. VLT refers to the percentage of visible light that can pass through a window. VLT, or “visible light transmission,” is what we use to help measure the darkness of a window tint.
