Midjourney prompt builder

A Midjourney prompt is a vivid description plus parameters like --ar, --stylize and --chaos. Compose and reuse them faster with snippets and saved presets.

How Midjourney prompts work

  • Structure: a clear image description first, then style references, then parameters at the end.
  • Key parameters: --ar 16:9 (aspect ratio), --stylize 250 (artistic strength), --chaos 20 (variety), --no thing (exclude), --v 6 (model version).
  • Weight phrases with double colons: forest::2 fog::1 makes the forest twice as important as the fog.
  • Image references go at the very start as URLs; style references use --sref.

Example Midjourney prompt

a weathered fisherman mending nets on a misty harbour at dawn, soft rim light, muted teal palette, photojournalistic, 35mm --ar 3:2 --stylize 300 --v 6

Frequently asked questions

What does --stylize do in Midjourney?

It controls how strongly Midjourney applies its house aesthetic. Low (50–100) stays literal to your prompt; high (500+) is more artistic and stylised.

How do I set the aspect ratio?

Append --ar W:H, for example --ar 16:9 for widescreen or --ar 2:3 for portrait.

How do I weight parts of a Midjourney prompt?

Use :: with a number, e.g. castle::2 fog::1 makes the castle twice as important as the fog.
