Image Size for PPT Presentations

The following slide provides you with the dimensions for images used in a PowerPoint presentation. Images with a resolution of 72 ppi will successfully project with little distortion according to the different dimensions provided. Many slide projectors will project at higher resolutions, which means you can increase your resolution from 72 ppi to 150 ppi for images used in PPT. Higher resolutions than 150 ppi will result in slow uploads to the screen.
