How to check resolution of UVs?
 

Hey all,

First time getting into texturing after finishing a model in zbrush,
and bringing it into Maya I see the first step is UVs

Now Im following a tutorial and the tutorial has given me their final model as a reference.
Now I hear about 2k,4k,8k, etc maps all the time
and wanted to check what was the size of the UV map of the teachers model so I can do the same for mine.

However I have no idea where I can find the value, anyone know?
