Quick body measurements for type of tri bike to ride?

I’ve searched through the fit articles here. Maybe I just missed it, but, are there a few anatomical measurements I can take to determine (at least in the ballpark) what type of tri bike my body is suited for (long/low versus short/tall)?

P.S. I really don’t feel like paying a shopt $75 to take measurements with a tape measure to determine this. Especially when I can’t guarantee I won’t “magically” fit the bikes they sell.

I’m curious to know as well.

Seriously, nothing on this?

there is (or at least used to be) a calculator tool, similar to what you are seeking on competitivecyclist.com. Unfortunately it is more geared to road bike sizing than tt bikes, but it may be a good start.
