It refers to the number of pixels within one square inch on a digital screen.ĭPI (dots per inch) refers to the number of dots of ink in one square inch of a printed image. PPI-pixels per inch-is the digital equivalent. DPI-dots per inch-is a printing term that identifies the number of dots of ink in one square inch of a printed image. It’s essential to understand DPI and PPI if you want to resize an image or photograph without losing quality. Pixel density leads us to another couple of technical terms related to image resampling-DPI and PPI. Therefore, to enlarge an image without losing quality, pixel density must be taken into account when resizing. If you printed it at 20 x 20, however, you’d encounter image quality issues because the density of the pixels would be lower. If you were to print this image at 10 x 10 inches, the density of the pixels would be sufficient for a nice, high-quality print. The more pixels, the higher the resolution. The more pixels, the higher the resolution.Ī 3000 x 3000 pixel image could be considered a high-resolution image for digital use, for example, appearing to be large on your screen. Simply put, resolution is the relationship between the dimensions of an image and the number of pixels contained within those dimensions. If you enlarge images without careful resampling, the number of pixels in your image will remain the same, creating a blurrier, pixelated result and a lower resolution quality (see below).Ī macro shot of pixels on a screen. In terms of how to resize images without losing quality, the important thing to remember is that the more pixels you have making up an image, the crisper and better quality the image will appear. You can think of pixels as tiny building blocks of graphic information. 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.
