Smallest I could ride?

[ahlam1399]

I'm 5'3 and 58kg (127lbs) I usually ride a 15.2hh Cob but I was wondering how small I could go. I've ridden a 12.2hh Welsh before (in the picture) but that was just once a week for 15mins to exercise him. I know it depends on horse breed, how fit they are etc but in general what does everyone think?file:///home/chronos/u-aa84cd2c7ab212bf800e03fa7b5910a30e92da09/Downloads/image_123923953.JPG
