Image sensors form pictures in different widths and heights, often referred to as aspect ratios. The aspect ratio of the sensor is the dimension of the digital image or the image output to print. Understanding the dimensions of the image and the anticipated resolution will provide an idea as to the proportion of the image for placement into print or Web applications. An aspect ratio of 2:1 would mean the image will be 2 times wider than the height. The aspect ratio of a camera can be calculated by dividing the largest number of the resolution by the smallest number such as the following:
