What Percentage Window Tint Should You Choose?
A practical guide to VLT percentages — 5%, 20%, 35%, 50%, and 70% tint — plus state law and how to match shade to your goals.
Window tint percentage refers to Visible Light Transmission (VLT) — how much visible light the film allows through. The shade you choose affects privacy, heat rejection, glare, nighttime visibility, and whether your installation is legal in your state.
What VLT Percentage Actually Means
A 5% VLT film allows only 5% of visible light through, producing the darkest result. A 70% VLT film allows most light through and appears nearly clear from inside and outside.
5% Tint
Delivers maximum privacy and the darkest appearance. Legal for rear windows in most states but typically not on front sides; nighttime visibility is limited.
20% Tint
Popular for rear windows on trucks and SUVs — strong privacy while still allowing enough light for reasonable low-light visibility.
35% Tint
One of the most widely chosen shades for front side windows because it falls within the legal limit in many states while providing meaningful glare reduction.
50% Tint
Light tint with subtle darkening that reduces glare and UV without significantly changing glass appearance — common when buyers want protection without a visible tint effect.
70% Tint
Nearly invisible on glass, used primarily for UV and infrared protection where appearance must stay unchanged, including some windshield and commercial applications.
Matching Your Shade to Your Priority
Most states set a minimum VLT for front side windows, typically around 35%. Confirm legal limits for each window position before deciding.
- Privacy first 5% or 20% on rear windows where permitted delivers the strongest visual barrier from outside.
- Heat without dark look 50% or 70% paired with ceramic film delivers strong infrared rejection without a dark appearance.
- Balanced front windows 35% is the common street-legal choice for front sides in most US states.
Shade choice involves personal preference and legal requirements that vary by state. Choosing without verifying limits for each window risks citation or failed inspection regardless of film quality.
Working with an unverified installer increases the risk that illegal shades are applied without warning, leaving compliance risk entirely with the buyer.
