I am looking for a horse/pony that my 9 year old daughter and I can share. She will use it for 4-h and I would like to ride for exercise and pleasure. We have been looking for quite a few months to find a safe quiet mount that is well trained and in our price range. We tried a pony this weekend that meets our requirements; however she is advertised as 14.2 hands but really I think she is closer to 14 hands if that. On the plus side she is very stocky. I am 5'2 and 191 pounds. She is a great size for my daughter but I am wondering if she can carry me. On the trial ride she seemed fine but it wasn't a hugely long ride.
Generally horses are pretty tough. I would say it depends on the pony. I'm not sure that I'd agree that, say, a Welsh would be a good match.
However, you can get some pony crosses that have very substantial bone and can be the right height.
It's really hard to say without seeing pictures.
It REALLY irks me when I see adults riding mini's, though. Not that you are. That's just a side note.
Looking at the picture, she doesn't even look 14 hand to me too. Her ad says 14.2 but she has to be measured wrong. It seems to me that measuring horses is a very unscientific thing. I have been asking people how tall their horses are for over a year trying to get a handle on what size we feels right and one 15 hand horse looks enormous while another looks small. Makes horse shopping frustrating.
