What is the gullet size in most pony saddles?
Most Pony saddles have a “Pony Tree” with 4 1/2 inch gullet. They customarily do not make pony saddles with Quarter horse trees (with a 6 3/4 inch gullet) as the seat would be so wide it would be uncomfortable for a child to ride. If it helps I raised 4 kids on a saddle like this and rode Shetland ponies all the way to large AQHA horses. If you ride a full size horse you will a full size cinch, tie strap and off billets.
