Studio users: What Slide Size (Standard or Widescreen) Are You Using? Dec 07, 2015 By David Anderson Hey everyone! We were talking about aspect ratios today (yeah, geek chat) and were curious what your preferred aspect ratio was for Studio projects. Now that PowerPoint 2013 defaults to widescreen, it would seem that it would be the default ratio for e-learning projects. Is that fair? Can you help us with an informal survey by answering two questions: 1. What aspect ratio, standard (4:3) or widescreen (16:9), are you using for Studio projects? 2. Which version of PowerPoint are you using?
