Help with CC edit formats (PC, phones, tablets)

Hi Forum,

Im quite new to this, so sorry if im in the wrong forum for this :slight_smile:

But I need to make sure that my video and effects is suitable for both PC, tablets and phones, but I can’t fint a function in CC where I can see the margins in order to edit properly?

I guess(hope) that there is some place where I can get it to show like I draw my self in paint down below? Or is it the same format/view for both phone, PC and tablets?

Im using CC2019 on Windows.

Hope you can help a n00b out

Kind Regards
