i dont know if this has been covered, but im curious since i dont know what size is common for my height.
if you have a regular putter (not belly or other long putters), how tall are you and what size do you have?
Putting posture is so individual that I suppose while 33" might not be too long or short for someone your size, there's no reason you couldn't be equally comfortable with a different size. If your putting improved with a different stance and a 36" putter, wouldn't THAT be the right size for you?
I'm 6' 7" tall and tend to bend over quite a bit to putt. I use a 35" putter, but have an old putter from my childhood that is 33" and I occasionally use it. Anyone remember the Acushnet Bullseye putters? That's the one. You just can't throw them away.
