It is interesting that we speak of the photography of small (but not microscopic) objects as macrophotography (or photomacrography) given that "macro" is a particle of Geek origin that means "large."
My belief is that this reflects that the initial use of macrophotography (or photomacrography) was to distinguish it from the photography of microscopic objects (then called microphotography (or photomicrography), the particle "micro" being of Greek origin and meaning "small".
So the "large" objects shot in macrophotography are large compared to the objects shot in microphotography, but small compared to the objects shot in portrait photography (other than for pet spiders and the like).

A related curiosity is the custom of speaking of a macrophotographic setup as worthy of that name only if the image magnification is 1.00 or greater.
That mans that, with an 8" × 10" camera and such a qualifying setup, it would be suitable for photographing an object as small as, say, a lady's high-heeled shoe.
