Trimsheet Plane size ?

Elliott

Hi guys, 

I'm trying to make my first trimsheet texture using a plane as low poly in Maya who will be baked in substance painter. I saw multiples tutorials on the subject but every times, they make a different plane size. 

So, I don't know wich size that plane must be for a 2k texture for exemple. And how do you know the plane size for each texture size ?

Thank you for your time

It doesn't matter to SP at all. If you want to keep things in line with texel density in an engine, then 2x2m is pretty standard for a 2k texture, but that would only be relevant if you were importing the same plane into your engine for testing purposes. 
If you want to sculpt on it in Zbrush, then 2x2m is a good size for Zbrush tools.
