Im 61 (just to give you a framework on my physical) and have a flat right hand palm circumference at its widest point at 21.5cm or roughly 8.4in. The XL was a perfect fit. My hand was free to move, easy to take the glove off, plus the leather had a solid and very soft feel and smelled great! (Anyone whos ever bought gloves through online purchases knows faux leather and latex can be stinky.) I will order them again for a back up pair!
