Midjourney Parameters: Complete Reference

What Are Parameters?

Parameters are special options you can add to your prompts to control how Midjourney generates images. They allow you to adjust aspect ratios, stylization levels, randomness, quality, and much more. Parameters always start with -- and are added at the end of your prompt.

Quick Syntax
/imagine prompt: ... --param1 value --param2 value

Essential Parameters

ParameterAliasValuesDescriptionExample
--aspect--arwidth:height (e.g., 16:9, 4:5, 3:2)Sets the aspect ratio of the generated image--ar 16:9
--chaos--c0-100 (default: 0)Controls variation in the initial image grid. Higher values = more diverse results--c 50
--stylize--s0-1000 (default: 100)How strongly Midjourney applies its artistic style. Lower = more literal, Higher = more artistic--s 600
--quality--q.25, .5, 1, 2Rendering quality time. Higher values take longer but add more detail--q 2
--seed--seed0-4294967295Creates reproducible results. Same seed + same prompt = similar images--seed 123456
--stop--stop10-100 (default: 100)Stops generation at a percentage. Lower values = more abstract--stop 80
