The aspect ratio of an image displayed on a computer will be different from the aspect ratio of that same image displayed on a phone.Īspect ratios are a critical part of web content because images need to be uploaded at different aspect ratios for different uses, like desktop vs. However, an image’s aspect ratio will change depending on the medium in which it is presented. The relationship between its width and height determines the ratio and shape, but not the image’s actual size.

This means that an image measured in centimeters will have the same aspect ratio even if it was measured in inches. An aspect ratio does not have units attached – instead, it represents how large the width is in comparison to the height. For instance, a 6 x 4 inch image has an aspect ratio of 3:2. You will recognize it as two numbers separated by a colon in an x:y format. The aspect ratio of an image is the proportional relationship of the width to the height.
