Wood poles are manufactured in fixed lengths to keep stocking simple and installation predictable. The standard practice is to produce them in 5-foot increments, beginning at 30 feet. This means typical lengths include 30, 35, 40, 45 feet, and so on. Starting at 30 feet reflects common span requirements for many distribution installations, giving crews a length that works well for a wide range of poles while still allowing precise fit by stepping in small, 5-foot increments. The 5-foot spacing makes it easy to select a length that closely matches the needed span without having to carry many uncommon sizes.

Other options don’t align with how poles are typically stocked. 2-foot increments would create far too many smaller lengths and isn’t how poles are standardized. Beginning at 20 feet omits the widely used 30-foot length. Starting at 40 feet with 10-foot increments would skip the common shorter poles that crews rely on for many jobs.
