The size of giant things is really inconsistent in Naruto, and pretty much always has been. The best examples are Orochimaru when he used the Eight Branches Technique (those heads are supposed to be the size of Manda's) and Kurama greatly changing size between panels during Hashirama vs. Madara. That aside, it does seem like Susanoo is intended to change size, given we see users manifest miniature versions of its skeleton all the time. Sometimes Susanoo is small enough to fit on a tailed beast's (or rather Aoda's) head, and other times it's equal in size to one. Though the Complete Body form (and oddly Madara's third "armoured" form) are consistently tailed beast-size, aside from Hagoromo's, which only appeared in filler.
