Aspect ratio is the relationship between an image’s or screen’s width and height, usually written as width:height. For example, 16:9 is a common widescreen format, while 1:1 is a square format.

Quick Scoop

  • It tells you how wide or tall something looks, not how big it is overall.
  • Common examples:
    • 16:9 for TVs, laptops, and many videos.
* **4:3** for older TVs and some classic displays.

* **1:1** for square posts or images.

* **9:16** for vertical video like Shorts or Reels.
  • A ratio like 16:9 means that for every 16 units of width, there are 9 units of height.

Simple Example

If an image is 1920 x 1080 , its aspect ratio is 16:9 because 1920 divided by 1080 reduces to that ratio.

Why It Matters

Choosing the right aspect ratio helps content fit the screen properly and avoids cropping or awkward black bars.
