Leap of Faith and Cliffhanger use large enough platforms that it's not really an issue. Other jumping puzzles, especially the big one in Kugane, have tiny footholds that even a lalafell hangs off of.

And then once you manage to make it up the tower, you need to make a precise sprinting jump for the lamp post at the base for another point in the sightseeing log. That one's just sadism.
