Pole spacing calculator

Enter the road length, pole height and layout. You get a spacing range and a pole count range. It is a planning estimate, and a photometric report should confirm it.

How the estimate works

Spacing equals mounting height multiplied by a factor between 3 and 4. A staggered layout counts every pole along the road once, because poles alternate sides. An opposite layout doubles the count. A median layout uses one double-arm pole per station.

The result is a starting point. Tree cover, junction geometry, lux target, luminaire optics and maintenance factor all change the final number. Read the height and spacing guide for those details.
