Pitch	Pitch Angle
4/12	18.44°

The pitch of a skylight is calculated by the using the formula: pitch = arctangent of the rise / run. You may enter any degree of pitch from 15° to 45° or refer to the table above.

The pitch of your skylight will ultimately determine the overall height of the unit. For instance, an 8"x 8" pyramid with a 15° pitch would have an overall height of approximately 19 inches while the approximate height the same pyramid with a 45° pitch would be 54 inches.
