The amount of detail contained in any print or online image, such as a photograph image. 300dpi (dots per inch) is the“high-resolution” standard for printing. Printing at below this level will often result in obvious distortions or in the image appearing “pixelated” (showing dots rather than a consistent surface). Medium-resolution images (150dpi) are often acceptable for online flipbooks and digital editions, while low-res images (72dpi) are the norm for website images. It’s best to start with the highest DPI standard possible (300dpi for print, 72dpi for the Web) and stick to it, in order to avoid unexpected resolution problems.
