The --aspect or --ar parameter changes the aspect ratio of the image.

That's the width-to-height ratio of an image. It's normally expressed as two numbers separated by a colon, such as 7:4 or 4:3.

V5 introduces any aspect ratios. That means you can do crazy stuff like 100:1 (width is 100x longer than height).

Note: aspect ratio is not the same as resolution. An image can be 1000px × 1000px, or 1500px × 1500px, and the aspect ratio would still be 1:1.

Here are some common aspect ratios in real life, that you create Midjourney images for:

  • --ar 16:10 the standard for MacBook displays for years
  • --ar 16:9 iPhone takes pictures and videos at a 16:9 aspect ratio. The is also Youtube's most common aspect ratio
  • --ar 3:1 The Twitter profile banner
  • --ar 4:1 The Etsy shop banner
  • --ar 3:2 Most typical for film photography
  • --ar 3:2 / --ar 7:4 Common for art prints

The aspect ratio impacts the shape and composition of a generated image. Some aspect ratios may be slightly changed when upscaling.

Let's see the --ar command in action:
