Learn everything you need to know about Resolution

Resolution is defined as the ratio between the number of pixels into which the screen is divided, both vertically (height) and horizontally (width). For example, if we have a video resolution of 1920×1080, it means that it has 1920 pixels horizontally and 1080 vertically.

This term is fundamental when determining the quality of a video, since it measures the precision of the images within it. If we compare two fragments with fixed size and the same content, the one with a higher resolution will have more and, therefore, the image quality will be higher.

Let’s take a look at some of the most common resolutions:

  • 720P. Contains 720 pixels vertically and, generally, 1280 horizontally.
  • 1080P. Contains 1080 pixels vertically and, usually, 1920 horizontally.
  • 2K. Contains 1,440 pixels vertically and, frequently, 2,560 horizontally.
  • 4K. Contains 2,160 pixels vertically and, typically, 4,096 horizontally.
