Midjourney Parameters Explained: How to Control the Output

Ready to take your Midjourney projects to the next level? Understanding Midjourney parameters is essential for anyone looking to produce consistently high-quality AI-generated art. In this guide, we’ll break down what parameters are, why they matter, and how you can use them to control everything from aspect ratio to stylization. Whether you’re a beginner or a seasoned pro, these insights will help you craft more effective prompts and get the exact visual output you envision.

What Are Midjourney Parameters?

In Midjourney, parameters are optional modifiers you add to your textual prompt to customize how the AI generates images. They control various aspects—like aspect ratio, rendering style, or even the version of the Midjourney model in use—to produce outputs tailored to your needs. Think of them as advanced settings that let you tell the AI exactly what you want, beyond just the subject and descriptive adjectives.

Parameters often appear at the end of your prompt, usually preceded by double hyphens (--). For example, --ar 16:9 sets a wide aspect ratio, while --v 4 selects version 4 of the model. Mastering these parameters is the fastest way to supercharge the quality and accuracy of your Midjourney art.

Key Parameters to Know

  • --ar (Aspect Ratio)
    Changes the image’s dimensions, e.g., --ar 16:9 for widescreen or --ar 1:1 for a square.
  • --v (Version)
    Specifies which version of the Midjourney model you want to use, e.g., --v 4 or --v 5. Each version may have unique strengths and stylistic nuances.
  • --seed (Random Seed)
    Fixes a particular seed for reproducible results. If you want the same prompt to yield the same image, use a seed value like --seed 12345.
  • --stylize
    Determines how “artistic” or abstract the final image will be. Higher values usually mean more creativity but can veer away from realism.
  • --uplight
    Produces moderate detail in the rendering. It’s a neat option when you want the output to be less cluttered, focusing on key elements.

How to Apply Parameters for Better Results

To use parameters effectively, simply append them to the end of your prompt. For instance, if you want a dramatic cyberpunk cityscape in a wide format, you might write:

/imagine prompt: A neon-lit cyberpunk skyline at night, rainy streets, futuristic buildings --ar 16:9 --v 4

Experiment by tweaking multiple parameters at once. For example:

/imagine prompt: A photorealistic portrait of an elegant phoenix with glowing feathers --ar 3:4 --v 5 --seed 2023 --stylize 50

In this case, you’re using:

  • --ar 3:4 for a vertical portrait style
  • --v 5 to harness the latest model’s capabilities
  • --seed 2023 for reproducible results
  • --stylize 50 to add a moderate level of artistic flair

Common Mistakes & How to Avoid Them

  • Overusing Parameters: While it’s tempting to stack multiple parameters, overloading can lead to confusion or unexpected results.
  • Conflicting Settings: Make sure your chosen parameters don’t contradict each other. For example, specifying --v 4 and --v 5 simultaneously isn’t possible.
  • Ignoring Prompt Quality: Parameters refine your art, but they can’t fix a poorly written prompt. Always start with a clear, detailed description.
  • Forgetting Community Standards: Some AI art communities have rules against certain content or aesthetic extremes. Use parameters responsibly.

FAQs About Midjourney Parameters

1. Can I use multiple aspect ratios in a single prompt?

No. Midjourney only recognizes one --ar value per prompt. If you list multiple, only the last one might be applied—or you’ll get an error.

2. How high should I set the --stylize parameter?

This depends on the effect you’re after. A lower stylize value yields more literal, controlled results, while higher values can produce more creative or abstract imagery.

3. Do all models support the same parameters?

Most core parameters like --ar and --seed are universal, but some advanced parameters may vary by model version. Always consult the latest documentation to confirm compatibility.

4. Is the --seed parameter always necessary?

Not necessarily. --seed is optional. Use it if you want consistent results for a specific prompt, or if you plan to compare outputs by changing only one other variable.

5. What if I want high detail without too much abstraction?

Consider using --uplight and moderate stylize values (e.g., --stylize 25). This combination can yield detailed yet cohesive images without overdoing artistic flourishes.

Conclusion

Midjourney parameters are the hidden levers behind precise AI-generated art, allowing you to control size, style, and even randomization. Mastering these commands will let you produce more predictable and intentional images, whether you’re crafting futuristic cityscapes, dreamy watercolor landscapes, or photorealistic portraits. Combine parameters with clear, well-structured prompts to unlock Midjourney’s full potential.
