Nozzle sizes that came with Ender 3

I did something stupid when I cleaned the nozzle clog a few days ago. Apparently I didn’t tighten it enough because it started forcing filament around the threads and caked the outside of the brass. I got it cleaned up, but as I was trying to get it back on, the wrench slipped and the nozzle disappeared into the void. Q1: what size is the nozzle that’s preinstalled? Q2: is the extra nozzle included in the bag of parts the same size? Any help would be greatly appreciated.

Hello !

Just for information (not the same type of nozzle, what is the version of your ender ?

And generally the default size is 0,4mm
