PPI is a measurement used to describe the density of what?

• A. Inches per pixel
• B. Dots per inch
• C. Pixels per inch
• D. Picas per inch

Answer: (C)

PPI describes how many pixels fit into one inch of a digital image or display, measuring the density of the image’s pixels. A higher PPI means more pixels per inch, so the image appears sharper and more detailed at a given size; a lower PPI results in a blurrier appearance when viewed at the same size. The other terms don’t match this concept: inches per pixel is the reciprocal of PPI, dots per inch refers to printer output and ink dots rather than screen pixels, and picas per inch isn’t a standard measure of image density.
