Depends. Canonically, the Transformers of the Beast Era were descended from the Micromasters, and on the show most of the characters were supposed to be around the size of biggish humans in robot mode. They were supposedly not using outright size changing in Beast Wars (which is why e.g. Waspinator is a freaking gigantic wasp), but as is almost always the case with Transformers properties, there was a lot of pretty dubious variation even when they were ostensibly trying to avoid it. For instance, Optimus Primal and Megatron were about the same size in robot mode, but their beast forms were wildly disparate in size.

Essentially, I think the true answer is (as it usually is in the actual TV shows), "Scale, schmale." :)
