What term describes the ratio of the size of an image to the number of grids per unit?

This concept is about how tightly detail is packed in an image. The quantity you’re describing—how many picture elements fit into each unit of length—is called resolution. It expresses the density of the image’s detail, essentially the ratio of image size to the number of grid samples per unit. For example, if a 2000-pixel-wide image is printed to 10 inches, you’re using 200 pixels per inch, which is a concrete way resolution quantifies how much detail appears in each inch. DPI is a related measure used mainly for printing and describes dots per inch produced by a printer, which is related but not the general term for the image’s density across any medium. Image size refers to the overall pixel dimensions, not how densely those pixels are arranged per unit length. Pixels per meter would be a density metric, but it isn’t the standard term used to describe this ratio in common imaging practice.
