Lightmap Pack question

Hi all,

I have a question concerning UV unwrapping using the Lightmap Pack option; I have researched the issue, but I could find no answer; I hope some of you can help. I’m using the latest release of Blender 2.8 Beta.

When I unwrap using Lightmap Pack, one of the options is “Image Size”; but, once the unwrap is done, is there any way to check the actual size in pixels of the UVs generated by the Lightmap Pack option?

Thanks in advance for all your help.
