Is it safe to use the above route spacing settings or should I consider to increase it a bit more?

CrossRoads

That's like 0.033", very very thin.
Change the grid view to inch, and make the traces at least 0.1".

0.127mm = 0.00127cm x 2.54"/cm =  0.0032"

Go with 0.16" or 0.2" for power traces.

CrossRoads, just laughed out loud... I use 0.15-0.16" for signal traces, and 0.24" minimum for power...  One of my boards features a +5V ring around the perimeter that is about 0.5" wide... keeps losses low! Probably overkill.

Actually I think I was off by a factor or 10.
I design with 0.02" (20 mil) for power, and 0.01" (10mil) for signal traces.

Whoops, me too. 15-16mil and 24 mil respectively, it is.

Yeah, I do 24mil too when I have power going out to LEDs or something.
