A digital image only has so many pixels, and print quality depends on how densely you spread them across the paper, measured in dots per inch. This calculator works both ways. Enter your image width and height in pixels along with a target DPI, and it tells you the largest print size you can make at that quality in both inches and centimeters. Or enter a desired print size and it tells you the resulting DPI so you know whether the result will look crisp or soft. Photo labs usually want 300 DPI for sharp prints held at arms length, while large posters viewed from a distance look fine at 150 DPI or even less. This helps you decide how big you can safely print without visible pixelation. Everything is calculated in your browser and nothing you enter is uploaded anywhere.
