I know Murderbot is canonically supposed to be tall even in the books but I cannot avoid picturing it as just. Completely average height. Absolutely dead center of the "height of an adult human" bell curve averaged across the entire Corporation Rim. Maybe at most average height for AMAB adults. Still marginally taller than many of the humans it interacts with but I really love the idea that it's physically completely unassuming when it's pretending to be a human. Technically 2cm shorter than average post Artificial Condition.
Not because whoever originally came up with the Secunit standard specs didn't want them to be imposing looking, necessarily, but because they are canonically cheap and built by the lowest bidder and you cannot tell me that a bunch of corporate beancounters would actually make those constructs 6'4" or whatever when they could make the maintenance cubicles and transport containers marginally smaller, and make the material costs of the cheap armor they're mass producing slightly lower, and save a very small amount of money on shipping costs every rental and so on, and make sure that if a situation ever requires putting one into an evac suit / enviro suit that they do not have to waste money ordering special models. I can't see them going "But if it's taller it can see over a crowd more easily" when they're designed to interface with security cameras and drones anyway" if they can be cheap bastards instead.
