Midjourney Parameter Cheat Sheet: Master Commands, Aspect Ratios & Modifiers (2026)

Midjourney v6 parameters control rendering mechanics, aspect ratios, image seeds, aesthetic weightings, and character consistency. Appending precise command parameters to the end of your prompt transforms random output grids into reproducible, production-grade visual assets.

1. Master Midjourney v6 Parameter Reference

| Parameter | Syntax Example | Valid Range | Core Function & Operational Mechanism |

| :--- | :--- | :--- | :--- |

| Aspect Ratio | `--ar 16:9` | Any integer ratio | Controls canvas width-to-height dimensions (e.g. `16:9`, `9:16`, `1:1`, `4:5`). |

| Stylize | `--stylize 250` or `--s 250` | `0` - `1000` | Controls strength of Midjourney's default aesthetic filter. |

| Chaos | `--chaos 20` or `--c 20` | `0` - `100` | Controls initial grid diversity. Higher values produce distinct compositional variations. |

| Weird | `--weird 500` or `--w 500` | `0` - `3000` | Introduces eccentric, surreal, and unconventional visual elements. |

| Raw Mode | `--style raw` | Fixed flag | Decreases default Midjourney artistic opinion; maximizes photographic realism. |

| Style Reference | `--sref https://...` | Image URL(s) | Transfers color, texture, and aesthetic style from reference image. |

| Character Reference| `--cref https://...` | Image URL | Maintains character facial consistency across scene prompts. |

| Character Weight | `--cw 100` | `0` - `100` | `--cw 100` tracks face, hair, and clothing; `--cw 0` tracks face only. |

3. Parameter Troubleshooting Matrix

Issue: Subject faces distort when using high --stylize values.

- Fix: Reduce `--stylize` to `50` - `100` or append `--style raw`.

Issue: Character clothing changes unexpectedly between scenes.

- Fix: Increase character weight to `--cw 100` and describe explicit clothing items in the text prompt.

Issue: Output grid variants look identical.

- Fix: Increase chaos value to `--chaos 25` or `--chaos 50`.

Frequently Asked Questions

What is the default stylize value in Midjourney v6?

The default --stylize (--s) value in Midjourney v6 is 100. Values range from 0 (strict prompt adherence, raw realism) up to 1000 (maximum artistic interpretation).

How does the Style Reference (--sref) parameter maintain brand consistency?

--sref allows you to pass one or more image URLs into your prompt. Midjourney extracts the color palette, lighting, texture, and aesthetic style of the reference image and applies it to your new generation.

Can I combine Character Reference (--cref) and Style Reference (--sref) in a single prompt?

Yes! You can use --cref [URL] to lock in a character's facial features alongside --sref [URL] to lock in environmental art style.
