Pole Height Calculator

Determine the optimal pole height for outdoor lighting based on coverage area, spacing-to-height ratio, and fixture beam angle. Calculates the illuminated circle diameter and recommended setback from obstruction.

Choosing pole height for area lighting

Pole height drives how much area each fixture covers and how even the light is. Taller poles light a wider area with fewer fixtures, but the light arrives at a shallower angle, so you need well-controlled optics to keep it on the ground rather than spilling sideways. A common planning rule ties spacing to height: fixtures are often spaced about 3 to 4 times the mounting height apart for general area lighting, tightening that ratio where you need higher uniformity. Typical heights run ~12–15 ft for walkways and small lots, 20–30 ft for parking areas, and 30–40+ ft for large lots on high-mast poles. Taller poles also raise glare and aiming sensitivity, so balance fewer poles against uniformity, maintenance access, and local height limits.
