Window Tint Darkness Calculator
Window Tint Darkness
Calculate window tint percentages, visible light transmission, and estimated cost for different tint levels and window counts.
Formula
Total Cost = (Number of Windows x Cost Per Window) + Windshield Strip; VLT = Percentage of visible light passing through; Heat Rejection varies by film type (15% dyed to 70% ceramic)
Frequently Asked Questions
What tint percentage is legal?
Legal VLT varies by state and window position. Most states allow 35 percent or darker on rear windows but restrict front side windows to 35 to 70 percent VLT. Always check local laws before tinting.
What does VLT mean?
VLT stands for Visible Light Transmission, the percentage of visible light that passes through the film. Lower VLT means darker tint. A 5 percent VLT allows only 5 percent of light through.
Is ceramic tint worth the extra cost?
Ceramic tint provides the best heat rejection without interfering with electronics, and it does not fade over time like dyed films. It offers the best combination of visibility and heat reduction.
