The scale ranges from Class 1, the darkest skies available on Earth, through Class 9, inner-city skies. It gives several criteria for each level beyond naked-eye limiting magnitude (NELM). The accuracy and utility of the scale have been questioned in recent research. The table below summarizes Bortle's descriptions of the classes.

One of the easiest ways to identify the brightness of your night sky is to use the Bortle scale. A light pollution map will show that a large city radiates white to red from the center, and rural areas will appear green to blue. These colors represent the amount of artificial light in the area, and how bright the night sky will look.
