Image Resolution refers to the level of detail that any digital design or printed product has. The higher the resolution of digital design, the sharper the image will look when it’s printed. To get the correct ‘level of detail’ for your image, you need to look at the number of pixels or dots contained within that image. The image resolution is measured by the number of dots or pixels within a linear unit.

A dot or a pixel is the most basic or the smallest element of an image. If you zoom in on an image very close, you will see pixels and dots.

DPI stands for Dots per Inch. DPI is a measure of the number of dots that will fall side by side along one inch. So, the higher the DPI, the higher the printed resolution.
