An electronic bubble level display is provided for determining surface normality when coupled with three sensors (18, 20, 22) sensing distance to the surface. The signals from the sensors are provided to an electronic processor (34) for computing the surface angularity and translating the angularity to specific positions on an LED dot matrix display chip (38).
