Using Parameters in Midjourney: Aspect Ratios, Quality Settings, and Style Controls

In Midjourney, parameters are modifiers added to prompts to control image generation aspects such as aspect ratio, quality, and style. They are appended at the end of your prompt with a double dash --.

Aspect Ratios (--ar or --aspect)

• Controls the shape of the image by setting the ratio of width to height (e.g., 16:9, 4:3, 1:1).
• The default aspect ratio is 1:1 (square).
• You can specify arbitrary integer ratios since version 5.0.
• Aspect ratio affects composition and framing but not the absolute pixel size.
• Common uses:
  • 16:9 for cinematic or video-style images.
  • 21:9 for ultra-wide cinematic looks.
  • 9:16 or 1:2 for vertical formats like stories or reels.
  • 1:1 for social media posts or balanced compositions.

Quality Settings (--q or --quality)

• Controls the rendering detail and processing time.
• Values can be 0.25, 0.5, 1 (default), or 2.
• Higher quality (--q 2) produces more detailed images but uses more GPU time and credits.
• Lower quality (--q 0.25 or 0.5) renders faster with less detail, useful for quick or abstract results.
• Adjusting quality helps balance speed, cost, and image refinement.

Style Controls (--stylize or --s)

• Determines how much Midjourney applies its artistic style to the image.
• Range: 0 (raw, literal interpretation) to 1000 (highly stylized).
• Lower values produce images closely matching the prompt with less artistic flair.
• Higher values create more abstract, artistic, or imaginative results.
• Default stylize value is around 100.
• Useful for controlling creativity level and visual abstraction in outputs.

Additional Notes

• Parameters can be combined in any order to refine results (e.g., --ar 16:9 --q 2 --stylize 500).
• Use --no to exclude unwanted elements.
• Modes like Standard and Raw affect how strictly the AI follows the prompt, with Raw being more literal and Standard allowing more creative freedom.

By mastering these parameters, you can tailor Midjourney outputs precisely for different formats, detail levels, and artistic styles.
