WINDOW TINT PERCENTAGES

What Window Tint Percentage Means

Tint percentage is normally discussed as VLT, or visible light transmission. A 70% VLT film allows more visible light through than 35%; 20% and 5% are progressively darker. The number describes light transmission, not heat-rejection performance.

70% VLT

70% is a very light appearance. It is commonly considered when the goal is performance with minimal visual darkening, subject to the glass, film and applicable law.

50% VLT

50% is a light tint that creates a more noticeable change while preserving substantial visibility. It can be useful for drivers who want a subtle appearance.

35% VLT

35% is a visibly tinted appearance and a common comparison point because current North Dakota state guidance references 35% light transmission for certain windows. The combined glass-and-film result still matters.

20% VLT

20% is dark. It can create significantly more privacy and a stronger visual change, but it is not appropriate for every window or every legal situation.

5% VLT

5% is extremely dark and is often called limo tint. It should not be treated as a universal road-legal choice.

Factory Glass Changes the Starting Point

An SUV or truck may already have dark rear privacy glass. Adding film over factory-dark glass creates a different final VLT than applying the same film to clear glass. That is why the Bismarck Tint simulator asks for the factory-glass baseline before previewing film shades.

Darkness Is Not the Same as Heat Rejection

Do not choose a shade solely because you want better heat control. Film construction matters. Ceramic film can deliver stronger solar performance without requiring the darkest appearance.
