I'm the same height as you are, and my Morgan mare is either 14.2 or 15hh depending on how you hold the measure tape and squint. Lol We fit each fine. 14.2hh should be no problem at all for you so no worries! Like others have said, the smaller ponies depends on their build and your leg length (I have short legs so I really enjoy riding ponies). Good luck and have fun!
