Best aspect ratios for YouTube uploads

The standard YouTube aspect ratio for a computer is 16:9. If your video has a different aspect ratio, the YouTube video player will automatically change to the ideal size to match your video and the viewer’s device.

Let’s take a look at some of the best aspect ratios for YouTube video uploads, including the top use cases and pros and cons for each.

16:9 aspect ratio

The 16:9 aspect ratio is the top-used aspect ratio on YouTube for a reason. Widely used in filmmaking, broadcast television, and online streaming platforms, it’s the standard aspect ratio for HD and Full HD content on most TVs, monitors, and devices.

Pros:

  • Creates a balanced and symmetrical appearance.
  • Works well for mobile viewing as it occupies more screen space.

Cons:

  • May require extra effort in framing shots.

4:3 aspect ratio

This aspect ratio was commonly used in older TV sets and some digital cameras. However, it can stil be suitable for certain types of artistic or nostalgic videos where a vintage look is desired.

Pros:

  • Can evoke a sense of nostalgia or classic filmmaking.

Cons:

  • Not optimal for modern widescreen displays.
  • May result in letterboxing (black bars on the sides) when viewed on newer devices.

Cons:

  • Can limit the viewing experience on larger screens or traditional formats.
