Hi. Richard:

So I think what or asking is how do I calculate the creepage and
clearance necesary for a given volltage.

I remember seen a small blurb on this in ipc-2221

You will need the voltage, the dielectic constant
(I belive the table is for air - outer layer trace)
And altitud.  The chart will then give you air gap necessary beetween
the two conductors.

If you don't have ipc-2221 try googling electrical creepage and clearance.

Hope that helps

Carlos
