I guess it's a bit of a quibble about using the term "size" that goes way back. But whenever we talk about the size of an object, whether it's a galaxy, an elephant, an atom, or a neutrino, we have to define exactly what it means. The definition Richard gives is as good as any and, since Rutherford, I think the most common for these objects. And, actually, since each of the atoms of the elephant don't have a size in the way that we think of size, neither does the elephant itself - no matter how you define that size.
