Geometry-first estimate
How many feet of lights does this route need?
Rooflines are straight runs. Posts and trunks are circumference repeated up the height. Controllers and outlets add their own travel. Measure each job separately.
Length is not electrical capacity
This result plans physical route only. The exact string and controller instructions still set connected-run, wattage, location, and extension limits.
Current safety boundary: CPSC seasonal and decorative lighting guidance. Route length never overrides product markings or instructions.
