Question: Does anybody know how to calculate the width of a 50 Ohm
microstrip line on Arlon PTFE circuit board (Type GX-0065-45-11). It is
0.0065" thick, double sided and has a k=2.45. Looking at my chart, it
looks like I leave the bottom as complete copper groundplane and take
off all copper around stripline on the top side of the board and leave
the stripline as 0.0195" wide? That doesn't sound very wide!!

It isn't very wide at all.

I've built stuff on 15 mil 5880, twice as thick as your
paper-thin material. And it was still a handful.

What are you building? Why so thin?
