Should I get 35 or 20 tint?

Whether you should get 35 percent or 20 percent window tint depends on your priorities for privacy, legality, night visibility, and heat rejection. 35 percent tint allows 35 percent of visible light through, so it is lighter, while 20 percent allows only 20 percent through, so it is noticeably darker. 35 percent is often considered the best all-around choice for front side windows because it provides good heat and UV rejection, reduces glare, offers moderate privacy during the day, yet still allows decent visibility at night and is closer to legal limits in many states, including California where front windows must allow 70 percent, so even 35 percent is technically illegal on fronts but less likely to be noticed than 20 percent. 20 percent provides more privacy, better heat rejection, and a darker, more stylish look, especially on rear windows, but it makes night driving harder, especially in poorly lit areas, and is more likely to attract attention from law enforcement on front windows. Many people choose a combination, 35 percent on front side windows for better visibility and legality, and 20 percent on rear side and back windows for privacy and heat. If you drive a lot at night or in rural areas, choose 35 percent, if you prioritize privacy and aesthetics and mostly drive in cities, choose 20 percent for rear windows.
