What Is DPI? Is It the Same as PPI? Macro shot of “halftone” ink dots printed on paper. If you were to print it at 10 x 10 inches, the density of the pixels would be sufficient for a high-quality print, but you’d encounter image quality issues at a significantly larger print size (like 20 x 20 inches) because the density of the pixels would be lower. A 3000 x 3000 pixel image could be considered a high resolution image for digital use, appearing large on your screen. The more pixels, the higher the resolution. Simply put, resolution is the relationship between the dimensions of an image and the number of pixels contained within those dimensions. However, newer computers and mobile devices have the ability to display more pixels in a smaller physical space, resulting in a crisp, smooth appearance. On older computer monitors, these pixels were more easily visible because they were less dense.
“Pixel” is a portmanteau of “picture” and “element.” You can think of pixels as tiny building blocks of graphic information.Įverything you see on a screen is comprised of pixels. Pixels are the standard unit of measurement for screens.
Let’s start with some common questions and vocabulary pertaining to image resolution. Today, we’re learning all about the lingo of image resizing, how to quickly determine image resolution, how to convert from inches to pixels, centimeters to pixels (and vice versa), and how to resize your image using Adobe Photoshop or Shutterstock Create, all while retaining quality.
