When is a horse not a horse?

A horse under a certain number of hands (a unit of measurement) is called a pony.

The correct term for a horse under four years of age is called a foal, if it is male then a colt and if it is a female, a filly.

If a horse is 14.2hh (hands)or more, (144.272cm) then it is classed as a horse and cannot enter pony classes.

If it is under 14.2hh (144.272cm) then it is classified as a pony.

There are some horses and ponies that are just on the line and you can make them a horse or a pony by shoeing and hoof trimming.
