On that topic - I was taught that a rough guide to how long your leathers should be was to put your fingertips against the stirrup bar and if the iron reached to your armpit that was a good starting point.
Me too!!! My instructor says I should ride with them that length, but I always end up shortening them
My second horse had a racing saddle, and I went through a brief phase of wanting to be a jockey (but I grew too much!) and my position has never recovered from all those days spent with stirrups about 2' long! I still ride too short!
