* Height is measured in hands, not hh: The height of a horse is measured in "hands," not "hh." One hand equals 4 inches.
* Breed standards matter: Horse height is often categorized based on breed standards. For example, a pony is generally defined as a horse under 14.2 hands high.
* No single "under 14.2 hands" term: There's no standardized term for a horse that's under 14.2 hands, regardless of breed.
Here's what you could use instead:
* Pony: If the horse fits the general definition of a pony (under 14.2 hands), you can call it a pony.
* Small horse: This is a more general term for a horse that's smaller than average.
* Yearling/Weanling: If the horse is very young, you could refer to its age instead of its height.
If you're unsure of the specific term, it's always best to ask an experienced horse person or refer to breed standards.
