Which of the following describes the relationship of width and height of an image?

The relationship of width and height of an image is referred to as the aspect ratio. This term specifically defines the proportional relationship between the two dimensions, which is often expressed as two numbers separated by a colon (e.g., 16:9 or 4:3). Understanding aspect ratio is crucial in various fields such as video production, graphic design, and photography, as it affects how images are displayed and perceived. A proper aspect ratio ensures that images maintain their intended appearance without distortion when viewed on different screens or mediums.

The other terms, while related to image quality and display, do not accurately define the relationship of width to height. Resolution pertains to the number of pixels in an image and dictates its clarity and detail, while pixel density refers to the amount of pixels in a given area, influencing the sharpness of the image. Image quality is a broader term that encompasses several factors, including resolution and color accuracy, but it does not specifically describe the dimensions of an image.
