Midjourney Parameters and Pro Tips – Get the Result You Want

Parameters control aspect ratio, stylization, variety, and quality in Midjourney. This guide sums up the most useful ones and how to use them in real prompts.

👉 Use Midjourney

Core parameters (put at the end of your prompt)

Parameter	Short	What it does	Example
Aspect ratio	--ar	Width : height (default square)	--ar 16:9
Stylize	--s	How much the model “interprets” your prompt (more artistic)	--s 100 or --s 250
Chaos	--c	Variation between the 4 grids (0–100)	--chaos 30
No	--no	Things you don’t want in the image	--no text, watermark
Quality	--q	GPU time / detail (not resolution)	--q 1 or --q 2

Example:

a mountain cabin at dusk, smoke from chimney --ar 16:9 --s 150 --no text

Aspect ratio (—ar)

• 16:9 – Landscape, wallpaper, video thumbnails
• 3:2 – Photo-like
• 1:1 – Default square
• 9:16 – Portrait, stories

Use one --ar per prompt; it applies to the whole image.

Stylize (—s)

• Lower (e.g. 50) – Closer to your literal description.
• Higher (e.g. 200–300) – More stylized and “artistic”.

If the result is too far from your idea, try lowering --s.

Chaos (—chaos)

• 0 – Four images are quite similar.
• 30–50 – Noticeable variation.
• 80–100 – Very different options each time.

Useful when you want several distinct ideas from one prompt.

What to exclude (—no)

Add --no plus comma-separated words for things you don’t want, e.g.:

• --no text
• --no watermark, signature
• --no blurry, distorted hands

Multi-prompts and weights

Split the prompt with :: and optionally add a weight (number) so the model emphasizes one part:

forest :: river :: moonlight :: 0.5

Weights are advanced; start with simple :: splits and then try numbers if you need more control.

When to use other tools

• Describe – You have an image and want prompt ideas. Use /describe and then refine one of the suggestions.
• Style reference (—sref) – You want the look of another image (mood, colors, style).
• Image prompt – You want to mix your photo with text; put the image URL in the prompt.

Pro tips

1. One main idea per prompt – One subject + one style + one or two parameters often works better than long lists.
2. Iterate – Use U1–U4 to upscale, V1–V4 to vary; then adjust the text and run again.
3. Save good prompts – Keep a note of prompts (and parameters) that work so you can reuse and tweak them.
