It is important that your saddle pad is based on the length of the saddle, and not necessarily on the length of the horse’s back. The saddle pad should always be slightly longer than the saddle. The saddle pad model should also match the saddle model (e.g. dressage, allround).

P (Pony) saddle pads generally fit saddle sizes 14-16.5

F (Full) saddle pads generally fit saddle sizes 16-18.5

Pony size fits all horses less than 148 cm (14.2 hh) high at the withers. "Full" fits all horses over 148 cm (14.2 hh) at the withers.
