I'm 5.2ft and rode my two 13.2hh veterans until last year. I now have a 17hh and will be riding my remaining 13.2hh also this year. No pics on the work Pc but i look fine on both. (maybe ride with longer stirrups on the big boy though )
Im 5ft 9 & 8 stone & Cooie (templedruid sauvignon) hadly knows im there, she also does marathon trials with her disabled driver with ease despite both driver & backstep being larger ladies.
really being miss being able too pop on Cooie for a ride but following drs advice on the vain hope i can ride again one day.
most ponies really are deceiving in their size/weight ratio's.
You will be fine I did a lot of work with an 11something welsh a he carried me fine and could still leap over puddles and different coloured grass and his favourite thing to do was to go for a good blast. I'm 5'2 and around 8 stone so I'm sure you will be fine at the same time I was also riding a 13hh new forest who loved fast hacks. I currently own a 14.2 Connie who also carries me without any problems even my dad has hopped on for a walk about on him I will try to find some pictures for you but if you want to see my current boy I posted some videos a while back.
I own and ride western a 13hh grey fell mare and a black 13.2 fell mare, I am 5'2" and very fat! They carry me and a big western saddle no probs but I only ride no longer then an hour as I have an old injury. The are fine and happy with it all, doing all western manovers.
I am 5'9"....not particularly skinny, probably about 12 and a half stone, 13 stone defending on how much cake I've eaten
This is my 14 hand, very chunky traditional cob.....as you can see, he's really struggling!!
Because he is so wide, he also takes up my leg nicely
this is me on an 11 something we had just hacked 2.5 miles and then went round the fields a few times before hacking back so we did over 5 miles that day and not at any point did he struggle, in fact he was still full of energy.
and this is me on a 13hh new forest
and this is my 14.2
and again (had a play on photo bucket with this one)
