Understanding the Resolution of Digital Images The resolution expressed in megapixels (MPX) In embroidery, the pattern of an image is created by placing colored dots on a grid, composed of a certain amount of squares. It is also the case for a digital image. The color dots, or pixels, are saved by a certain number of sensors, arranged on a grid. The more pixels, the greater the image details are fine. The "resolution" of the image corresponds to its size in pixels, often expressed in megapixels (MPX). It is calculated by multiplying the number of pixels in height by the number of pixels in width. Thus, for two images to the same "density" of pixels, the image at higher resolution will be of better "quality", because it provides finer details. Example The same image 600 x 900 px (0.54 mpx) and 1 200 x 1800 px (2.2 mpx). Example A pattern on a grid of 25 x 25 squares (625 squares) and 100 x 100 squares (10 000 squares).
