I don't know if sections is really the ideal measurement unit for trams – maybe metres makes a bit more sense. Double-articulated buses are usually around 25 m long. In Germany, the default maximum legal length for a tram running in road traffic (including on dedicated transit lanes [1]) is 75 m. Of course not every tram network goes up to that limit, but at least ~40 m isn't too uncommon, which also approximatively corresponds to the length of a seven-section Citadis (around 43 or 44 m). [1] Unless all intersections with road traffic are signalized as full-on railway-style level crossings.
