Window tints are popular everywhere, but if you live in a particularly sunny state like Florida, they're even more important. They can help keep the interior of your car cooler and even help reduce your risk of skin cancer.

If you're looking to reap the sun-blocking benefits of window tints, you need to know about the percentage ratings they use. Certain tints can offer you more benefits than others.

Read on to learn everything you need to know about window tint percentages.

Why Do Window Tints Use Percentages?

Every window tint has a percentage rating. This percentage is the amount of visible light transmission (VLT) that's allowed to pass through the car window.

For instance, a 20% tint will allow 20% of VLT to enter the car while blocking out the other 80%. The lower the percentage is, the more light it blocks. Darker tints will always have a lower percentage rating.

Chances are, your car's windows aren't 100% clear. Most car windows already come with some level of VLT-blocking capabilities. It's usually around 80%.

You'll have to do a bit of simple math to calculate the true VLT percentage. You'll multiply the existing tint with the tint percentage you plan to add to it.

Say your car already has 80% tint, but you want to add a 35% tint to it. You'll need to multiply 80% by 35%.

This works out to 28%, which means your windows will now block 28% of VLT.

What to Expect from Different Tint Percentages 

All auto window tints will be between 5% and 90%, with 20% and 35% among the most popular choices.

5% tints are the darkest window tint. They block almost all of the light that could come into a car, so they're reserved for special cases. Limousines use these tints to give their VIP clients the maximum amount of privacy.

20% tints are perfect for those looking to alter their car's appearance. These tints are quite dark, and passersby won't be able to see into your car. They block most VLT and cancer-causing UV rays.

35% tints are a great balance of practicality and aesthetics. Your car will take on a sleek appearance, and you'll be shielded from the sun. You'll also have no problem seeing through this tint level.

50% tints are perfect for those who want all the benefits of a window tint without darkening their windows. They're easy to see through and block half of VLT.

Tint Laws

Every state in America has different regulations regarding legal tint percentage. You'll have to keep the law of your state in mind when shopping for tints. 

If you install a tint that's too dark, you could be pulled over and issued a ticket. You'll also have to remove the tint and have a compliant tint installed.

Florida has different tint laws depending on the style of vehicle you drive and the kind of window you want to tint. In general, sedans must use a higher percentage than SUVs and vans, and front windows need to allow more light in than back windows.

You'll also have to consider the tint laws of your neighboring states. You'll be subject to those laws whenever you drive through them.

For instance, Florida generally allows darker tints than Georgia does. It might make sense to opt for a lighter tint to ensure you stay compliant wherever you go.

How to Choose a Tint Percentage

Now that you understand how window tint percentages are calculated and are aware that some tints are illegal, you're ready to choose a window tint. There are a few key points to think through.

Consider the Benefits

Window tinting offers a host of practical benefits. The ones that are most important to you inform your tint percentage choice.

Tints block UV rays which are a leading cause of skin cancer. This is the reason many people in sunny locales opt for window tints. UV rays can't penetrate the tint film of any percentage.

They can also protect the interior of your car from sun damage. Your dashboard and upholstery will last much longer if you tint your windows. Darker tints that block more VLT will be more effective for this.

Many window tints can also block infrared radiation, which helps keep the interior of your car cooler. You might even use less gas due to needing less air conditioning. High-quality tints of all percentages can block this radiation.

Think About Your Aesthetic

Some window tints will dramatically change the look of your car. A plain sedan can take on the appearance of a sleek road machine just by applying dark window tints.

However, some might not like the look of darker windows. These people can get many of the same advantages from a lighter tint.

Privacy

Darker tints allow for more privacy. They can prevent curious onlookers from peering into your car.

They could also help prevent car break-ins. Thieves won't attempt to steal from a car if they aren't sure it contains something of value.
