I am 6’ 2”, 210 lbs and I ordered the Large. This is my third golf shirt from Swannies and they all fit perfectly. Only suggestion I would make is that they make them a little longer as by the end of the day, they will be a little untucked and you’ll look slightly disheveled. If you’re like me you won’t care because you’ll be wasted by the end of the round anyway, and the way it fits now will allow you to wear the shirt outside of the golf course too other events. Cheers!
