Aren't electrons about 3 orders of magnitude smaller than a sub-atomic particles like protons? And I can't find an estimate of the diameter of a neutrino easily from google (do we even have one?), but it seems like neutrinos are even smaller still. And I think we still have a lot to discover in this area.

So maybe it's more like, about 40-50 orders of magnitude, but potentially much more as we explore the "extremely tiny" portion of the scale?

Quarks are supposed to be tiny. Why is the Top quark so gigantic?

As I understand it, it's believed that elementary particles (such as electron), don't have size.
