How to Determine the Resolution of a Digital Image

The resolution of an image generally determines its quality. The higher the resolution, the sharper and clearer images are. Digital images consist of multiple dots (pixels). The resolution of an image is determined by the number of pixels or dots per inch (DPI). Resolutions are also identified by the height and width of an image. On a PC or a Mac, use built-in tools to determine the resolution of your images.

If you are unsure of the location of your image, click the "Start" button in the left corner of your screen and click "Computer" to open Windows Explorer. Browse your computer for the image you are looking for by typing its name in the search box.

    Right-click on the image file and click "Properties." The image properties window launches.
