Aspect ratio expresses the proportional dimensions of the width and height of an image or screen. The number on the left of the colon represents the width (x axis) and the number on the right of the colon is the height (y axis). The two most popular aspect ratios are 4:3 and 16:9. These should look familiar to you if ever adjusted your TV screen or monitor settings before. The 4:3 aspect ration is the standard screen size for older TV’s and monitors and has a more box-like display. The newer high definition televisions and monitors today have the 16:9 aspect ratio which has a wider display. The 3:4 aspect ratio is useful in Divi for displaying portraits.
