What is resolution?

Resolution refers to the number of pixels in a digital image or display. It influences the sharpness and level of detail of the display. Resolution is usually given in pixel dimensions (e.g. 1920×1080) or in dpi (dots per inch) for print. In design, web and print, the right resolution is decisive for quality and professionalism. Higher resolutions are suitable for large-format or high-resolution applications, while lower values are often used in fast web applications.
