Graphic Design Terminology: Resolution
Resolution: All images have a resolution. Whether that image is displayed on a tv, computer, phone or printed in a book, brochure or magazine. Resolution refers to the detail of the image (see image below). Images with low resolution have less detail and images with high resolution have more details. Resolution is typically measured in pixels per inch (PPI) or dot per inch (DPI). These two measurements determine the amount of information displayed within a certain area. As a rule of thumb, screens use graphics that are 72 ppi and printed materials use 300 dpi. That’s why when you pull images off the internet and try to print them, the quality usually looks terrible. Printed materials require about 4x the amount of detail to look crisp. Check out the image below for an example of resolution. The image to the left is crisp and looses resolution to the right.
