How do I determine the correct driver length? I'm 5ft 8in tall.

Well, there's a few theories out there:

1) Driver length is irrelevant. Due to the low loft, having the club seriously toe up or down doesn't really effect anything. Play a length that's comfortable.

2) The USGA (and R&A) allow a maximum driver of 48". Since that's the max allowed, play it.

3) Using a Wrist To Floor (WTF) measurement, your ideal clublength is calculated using a standard chart.

4) Using a Wrist To Floor (WTF) measurement, your ideal clublength is calculated using a complex spreadsheet, based off an ideal golf setup position and the known lie angle of the club.

5) Demo like crazy. Hit progressively shorter drivers until you find a length that you can hit the fairway with 8/10 times. Or, start with shorter drivers and hit progressively longer ones until you dip below 8/10.

I use Option 4 (aka TrueLength Technology - http://www.danscustomgolfshop.com/truelength.html), and love it.

I say it too often: If it's golf club shaped, you can play with it.

For the record, I'm a club doctor, not a swing doctor.
