It depends on a variety of factors however most 33" putters work great for people your size. You could go to a local golf store and demo some Scotty Cameron putters that are 33" and 34" to double check.

The key is that you want the putter flat on the turf at address, you could adjust the lie angle up to two degrees flat or upright but generally 70 degrees is what most Scotty's come in since that covers the majority of people in golf, including myself! (I am 6 feet 6 inches tall!!)

Good Luck!

Just curious are you wanting to change style(s) or just upgrade? Like Chris said go and compare, even take your current putter so you can see how the new one looks at address compared to what you play now. Different styles (mallet, Blade, Futuristic) all look different at address. You might even check your current putter loft (3 or 4 degree) & match it as well.

Its all about how it feels in your hands and how it looks to your eyes. Good luck

33 is pr bably your best bet and have a club pro or a fitting pro look at your putting stroke he/she will be able to recommend a putter that suits your stroke the best

I agree with Chris, I went to PGA Super Store and demoed some Scotty's. Found the one I liked and Blammo it followed me home.

I think you should use a Scotty Cameron GoLo. It is my favorite putter. It's very forgiving and has great feel. I would talk to people at a local golf shop or golf club to see what you really need. Those are just reccomendations, but good luck and have fun!
