When you see lengths over 235, you are talking low angle style.  Also, the paddler's size is important.  A paddle at a minimum must be as long as the paddler's elbow to elbow distance (arm's outstretched) plus the length of the blades plus around 4".  For me, this means I can not have a paddle less than around 205 -- even for high angle.  A touring paddle shoud be around 25% longer than this minimum.

The following  was posted to rec.boats.paddle and works for me:
--------

A frequent question asked of this newsgroup is "what is the best paddle length for me?"

The usual answers are understandably vague as in:
     A taller person needs a longer paddle
     Use a shorter paddle for play-boating, etc.

In an attempt to give a more specific answer, I measured the  bodies, boats and paddles of several kayakers I know.  I then  put the question to the best engineering minds at my company.

They say the best fit of this data gives the following equation:

     PL = 2*BL+BS*(.38*EE+1.2*SQRT((BW/2-SW/2)^2+SL^2))

Where:
   PL = calculated paddle length in cm
   BL = blade length in cm
   BS = boating style factor
     Touring, use 1.2
     River Running, use 1.0
     Play Boating, use .95
   EE = elbow to elbow distance ( with your arms straight out to the sides ) in cm
   BW = boat width in cm
   SW = shoulder width in cm
   SL = spine length ( sitting down, measure the distance from the  chair seat to the top of your shoulder ) in cm
-------

I have this set up in an MS/Works spreadsheet (.wks) and can email it as an attachment to anyone with math phobia.  Remember to use cm for all measurements.
