It’s just modern cultural convention to linguistically differentiate them by their size. “Goblins” is a more archaic and folksy word for them.
The orcs referred to as Uruk-hai are members of that race that have been specially bred to be larger, more intelligent, and unphased by sunlight, but “Uruk-hai” just means “orc-folk” in the Black Speech.
