| 16:9 | --ar 16:9 |
YouTube Thumbnails, Desktop Wallpapers, Landscape Banner |
| 9:16 | --ar 9:16 |
TikTok, Instagram Reels, YouTube Shorts, Phone Wallpapers |
| 4:5 | --ar 4:5 |
Instagram Feed Posts, Portrait Photography Prints |

Frequently Asked Questions
What does the --ar parameter do in Midjourney?
The --ar (aspect ratio) parameter modifies the canvas dimensions of your generated image. Adding flags like --ar 16:9 or --ar 9:16 formats the output specifically for wide desktop monitors or vertical phone screens.
What is the difference between Midjourney v6 and RAW Mode?
Midjourney v6 applies automated cinematic stylization. Adding --style raw reduces opinionated defaults, granting strict adherence to your text prompt and photo-realistic lighting.
Can I use these generated strings on Flux.1?
Yes. Selecting Flux.1 or Stable Diffusion XL in our studio automatically formats the output command string to work across open-source AI generation tools.
Which aspect ratio is best for social media content?
Use 9:16 for vertical videos (TikTok, Instagram Reels, Shorts), 4:5 for regular Instagram feed image posts, and 16:9 for horizontal YouTube thumbnails.
Does changing aspect ratio reduce image quality?
No. Midjourney renders directly to your chosen aspect ratio during generation without stretching or cropping post-render, keeping detail high.
