Definitely try out the saddle first. They're all slightly different. I'm 5'4 and 135 pounds, and mine is a 17.5", fits me perfectly. Also, it depends on how YOU like your saddle to fit your bum! Many people like their saddles a bit on the large side because there's more room for your seat to move, while others want their seat to be wedged between the pommel and cantle for a more "secure" feeling. I would never buy a saddle without trying it out first on both you and your horse.
Where there's a bay, there's a way!
