Report Background Design

Hello,

I have been using powerpoint 2010 to design the backgrounds for my reports in Power BI. Typically I create all of my reports as 16:9 in Power BI and I also setup my powerpoints to be a custom size as 16:9.  I have noticed though when I do this the grids in powerpoint do not line up with Power BI and my powerpoint background tends to take many revisions until it actually fits in Power BI.

I know that using powerpoint as a way to design backgrounds was suggested in a webinar so I was wondering if anybody else uses powerpoint and has any tips on designing backgrounds. 

Thanks for any feeback!
