Hi,

how would I go around figuring out the nozzle size for my Kossel 2020 printer?

I've set it to the default 0.5mm but not sure at all it is the correct.

Additionally, I'm running 205C and bed 65C. The nozzle seems to be leaking plastic. It just doesnt look like a clean print, everytime I start printing, there's a bunch of ugly strands

Nozzle size can be determined by extruding in free air. Let the filament cool and measure the diameter with calipers.

The cause for a leaking hotend is often the way the nozzle is countered in the heater block.
The nozzle has to be countered against the M6 heatbarrier, NOT against the heater block.
