PowerPoint Image Resolution

When importing pictures and other graphics into PowerPoint, it is generally best to choose a resolution for those items that is at or near 1024 x 768 if you intend the image to be full screen. Anything larger will automatically be scaled down by PowerPoint. As a result the image may appear different than when displayed at a higher resolution. And a resolution larger than 1024 x 768 will offer no advantage on a monitor or projector that can only show that resolution.

Additionally, if you import images that are smaller than 1024 x 768, PowerPoint will manipulate the image up to the larger resolution of the monitor of projector. This can result in the image being less clear due to distortion.

If you are using an image that is larger than 1024 x 768 you can resize it to a smaller resolution in PhotoShop or other image manipulation software. In addition to making the image more compatible with PowerPoint, this process will also make the file size smaller. Presentations with smaller file sizes run more reliably. Also, a slide that includes a large image may advance less quickly because it takes more time to load.

Most projectors and monitors on the Williams Campus are setup to display a resolution of 1024 x 768. These figures represent the horizontal and vertical quantity of pixels (small dots, think impressionist painting) that each show different colors to create the image we see on a monitor or projected image. Currently, this may also be considered “standard resolution” for most computing, the exceptions being old computers and computers used for fine art work and high end still and video graphics.
