25% window tint
25% window tint lets 25% of visible light through the film. By the statute numbers it meets the front side window limit in 7 of the 50 states and DC and is darker than allowed in 44; on a sedan's back side windows it is legal in 27. One catch: the limit is metered through film and glass together, and on the car a 25% film usually reads about 18 to 20%, so a film that only matches the number can meter under it.
- Looks: Dark but still easy to see out of in daylight.
- Typical use: Front sides only where the limit is 25% or lower (Texas, Louisiana and a few others), and windows behind the driver in more states.
- Darker than allowed on front side windows in 44 jurisdictions, including Alabama, Alaska, Arizona, California.
- Exactly at or just above the front limit in 7 states, where a strict meter on darker factory glass can read under it.
What 25% tint looks like
Medium tint. 25% of visible light passes through; 75% is blocked.
- Heat rejection depends on the film, not the shade: a 70% ceramic film can reject more heat than a 20% dyed film.
- Legal minimums differ by state and by window. Check yours before you pick.
Where 25% tint is legal, state by state
Verdicts compare 25% with each state's statute number for passenger cars (sedans). "Legal" means it clears the limit even metered on darker factory glass (72%). *"Legal, at the limit" means it matches or just clears the number but can meter under it on darker glass, so have the installer meter your windows. Many states exempt SUVs and vans behind the driver, and most states with no limit behind the driver require outside mirrors on both sides; open a state for the statute, exemptions and tolerances.

Darkness is not heat rejection
The percentage only describes visible light. Most of the heat that warms a cabin is infrared, which a good ceramic film blocks at any shade. If the goal is a cooler car rather than privacy, a lighter ceramic film can beat a darker dyed one; see ceramic tint and compare published heat figures in the tint film comparer.
Frequently asked questions
Is 25% tint legal?
It depends on the state and the window. By the statute numbers, 25% meets the front side window limit in 7 of the 50 states and DC and is darker than allowed in 44. On back side windows of a sedan it is legal in 27; many states also exempt SUVs and vans behind the driver. The table on this page lists every state.
What does 25% tint mean?
The film lets 25% of visible light through on its own. Officers meter the film and the glass together, and factory side glass already blocks 20 to 28%, so a 25% film usually meters about 18 to 20% on the car.
How dark is 25% tint?
Dark but still easy to see out of in daylight. Front sides only where the limit is 25% or lower (Texas, Louisiana and a few others), and windows behind the driver in more states.
Does 25% tint block more heat than a lighter shade?
Only a little. Darkness is visible light; most of the heat you feel is infrared. A light ceramic film can reject more heat than a dark dyed one, so compare the film's total solar energy rejected (TSER), not the percentage.
