I work at a local tack store. And last night a man came in and was looking at saddles so I went over to help him. He was looking at a 13 inch saddle. His little girl sat in it and I was helping make sure it fit her and everything and the guy was like is this going to fit my pony (He asked kind of rudely) and I told him that I can't be 100% positive but it is a pony saddle. And he was like well she is just a pony she is like this tall (Holds his hand out to about his hip) and I was like well again I can't be sure because I don't know if it is a wider pony or skinny, or if she has high withers or if she is mutton withered. But this is a pony saddle so my guess would be it would fit, if you would like to try it out you can take the saddle for 3 days and try it out. He just got mad and was like nevermind. And him and his little girl went and looked at other items.
I know it isn't a big deal, but it bothered me because I was very friendly to him and was trying to help him, but he wouldn't understand that even though I was like 90% sure it would fit the pony, I can't be positive because all equines are built different.
