Pick This Tool If you have spent any time in Midjourney, you have probably seen prompts that look like a secret code. Words like “–ar 16:9” or “–stylize 750” appear everywhere, and if you do not know what they mean, you are leaving a lot of creative power on the table.
At Pick This Tool, we have spent countless hours experimenting with Midjourney’s parameters. Some transform your output dramatically. Others make tiny adjustments that matter only in specific situations. The good news is that you do not need to memorize all of them. You just need to understand the ones that actually change your results.
Let us walk you through the essential Midjourney parameters and commands so you can stop guessing and start creating with intention.
Midjourney Parameters at a Glance
Before I dive into each parameter, here is a quick reference table I use whenever I need a refresher. These are the commands I reach for most often.
| Parameter | What It Does | Common Values |
| –ar | Sets aspect ratio | 16:9, 1:1, 9:16 |
| –stylize | Controls artistic interpretation | 0 to 1000 |
| –chaos | Adds variety to results | 0 to 100 |
| –quality | Adjusts rendering detail | 0.25, 0.5, 1 |
| –seed | Repeats a specific result | Any number |
| –no | Excludes elements | Objects, colors, styles |
| –v | Selects model version | 5, 5.1, 5.2, 6 |
| –style | Applies preset aesthetics | raw, cute, scenic |
| –tile | Creates seamless patterns | No value needed |
| –iw | Sets image prompt weight | 0 to 2 |
What Exactly Are Midjourney Parameters?
Midjourney parameters are special instructions you add to the end of your prompt. They tell the AI how to interpret your request. Think of them as the settings on a camera. Your prompt is the subject you are photographing, and the parameters are the aperture, shutter speed, and ISO that shape how the final image looks.
Without parameters, Midjourney makes assumptions. It picks a default aspect ratio, a default level of artistic flair, and a default model version. Parameters give you control over those decisions.
The syntax is simple. You type two dashes followed by the parameter name, then a space and a value. For example: –ar 16:9 tells Midjourney you want a widescreen image.
One important note: parameters go at the very end of your prompt. If you put them in the middle, Midjourney might ignore them or get confused.
The Parameters That Matter Most
Not all parameters deserve equal attention. Some will transform your workflow. Others are niche tools for specific situations. Here are the ones we recommend learning first.
Aspect Ratio (–ar)
This is the parameter I use in almost every prompt. It controls the shape of your image. The default is 1:1, which gives you a square. If you want a cinematic landscape, use –ar 16:9. If you need a vertical image for Instagram Stories or TikTok, try –ar 9:16.
Why it matters: The aspect ratio changes how Midjourney composes the scene. A wide image encourages sweeping landscapes. A tall image pushes the subject to fill vertical space. Getting this right saves you from cropping later.
Example: /imagine a futuristic cityscape at sunset –ar 21:9
Stylize (–stylize or –s)
This parameter controls how much artistic freedom Midjourney has. Low values keep the output closer to your literal prompt. High values let the AI add its own creative interpretation.
The scale runs from 0 to 1000. At –stylize 0, you get something very literal. At –stylize 1000, Midjourney goes wild with artistic flourishes.
Why it matters: If you are generating product mockups or realistic scenes, keep stylize low. If you want dreamy, painterly, or abstract results, crank it up.
Example: /imagine a portrait of a queen –stylize 750
Chaos (–chaos or –c)
Chaos determines how varied your initial grid of four images will be. At –chaos 0, all four images look similar. At –chaos 100, they might look like they came from completely different prompts.
Why it matters: When you are brainstorming, high chaos helps you explore unexpected directions. When you have a clear vision, keep chaos low.
Example: /imagine a mechanical butterfly –chaos 50
Quality (–quality or –q)
This parameter adjusts how much time Midjourney spends rendering your image. Lower values render faster but with less detail. Higher values take longer but produce finer results.
The scale is 0.25, 0.5, and 1. The default is 1. Using –quality 0.5 cuts your GPU usage in half, which matters if you are on a limited plan.
Why it matters: For quick concept sketches, drop the quality. For final pieces, keep it at 1.
Example: /imagine a detailed steampunk watch –quality 0.5
Seed (–seed)
Every image Midjourney generates has a seed number. If you use the same seed with the same prompt, you get the same result. This is invaluable for consistency.
Why it matters: If you generate an image you love and want to make small tweaks, lock the seed. You can change your prompt slightly and see how the output shifts without losing the overall composition.
Example: /imagine a cozy cabin in the woods –seed 12345
No (–no)
This parameter tells Midjourney what you do not want in your image. It is a negative prompt.
Why it matters: Sometimes it is easier to say what you do not want than to describe exactly what you do. If Midjourney keeps adding trees to your desert scene, use –no trees.
Example: /imagine a minimalist workspace –no clutter, cables, mess
Version (–v)
Midjourney releases new model versions regularly. Each version has its own strengths and aesthetic tendencies. You can specify which version to use.
Why it matters: Some prompts work better on older versions. If you loved the look of V5 but V6 changes things, you can still access V5.
Example: /imagine an oil painting of a stormy sea –v 5.2
Style (–style)
This parameter applies preset aesthetic styles. For example, –style raw reduces Midjourney’s default beautification, giving you more control. –style cute adds a playful, adorable quality.
Why it matters: Styles are shortcuts. They save you from writing long descriptions of the look you want.
Example: /imagine a robot chef –style cute
Tile (–tile)
This parameter creates seamless repeating patterns. It is perfect for textures, wallpapers, and fabric designs.
Why it matters: If you need a pattern that tiles without visible seams, this is the only way to get it in Midjourney.
Example: /imagine a floral pattern –tile
Image Weight (–iw)
When you use an image as part of your prompt, this parameter controls how much influence that image has. Higher values make Midjourney stick closer to your reference.
Why it matters: If you are trying to replicate a specific style or composition from a reference image, increase the image weight.
Example: /imagine prompt: [image URL] a portrait –iw 1.5
Commands vs. Parameters: What Is the Difference?
This trips up a lot of beginners, so let me clear it up.
Parameters modify a single prompt. They go at the end of your /imagine command. Examples include –ar, –stylize, and –chaos.
Commands are separate actions you type into the chat. They start with a forward slash. Examples include /imagine, /blend, /settings, and /info.
Think of parameters as settings and commands as tools. You use a command to start a task, and you use parameters to fine-tune how that task runs.
Essential Commands Worth Knowing
- /imagine – The core command. This is how you generate images.
- /blend – Upload two to five images, and Midjourney merges them into one.
- /settings – Opens a menu where you can set default parameters for all your prompts.
- /info – Shows your account status, subscription tier, and GPU usage.
- /describe – Upload an image and Midjourney suggests prompts that could recreate it.
- /shorten – Analyzes your prompt and suggests which words are most important.
How Do You Choose Which Parameters to Use?
At Pick This Tool, we suggest a simple approach. Start with just one or two parameters. Master them. Then add more.
Here is the order we recommend:
- Step 1: Learn –ar. Aspect ratio affects every image, and it is easy to understand.
- Step 2: Add –stylize. Once you know how much artistic flair you want, your results become more predictable.
- Step 3: Experiment with –chaos when you are brainstorming. Lower it when you are refining.
- Step 4: Use –seed when you find something you like and want to iterate.
- Step 5: Explore the rest as needed. Parameters like –tile and –iw are powerful but only for specific use cases.
Do not try to use every parameter in every prompt. That leads to messy results and confusion. Simplicity wins.
Common Mistakes to Avoid
I see the same errors repeatedly when helping people with Midjourney. Here is how to sidestep them.
- Putting parameters in the wrong place: Parameters go at the end of the prompt. Always.
- Using conflicting parameters: Do not use –quality 0.25 and then complain about lack of detail. Understand what each parameter does.
- Overloading the prompt: More parameters do not mean better images. Each one adds a constraint. Too many constraints create chaos.
- Ignoring the version: Different versions handle parameters differently. If a parameter is not working, check which version you are using.
- Forgetting to experiment: The best way to learn is to try. Generate the same prompt with different parameter values and compare the results.
What Do Readers Ask About Midjourney Parameters?
What is the most important Midjourney parameter for beginners?
Aspect ratio (–ar) is the one we recommend learning first. It has an immediate, visible effect on every image, and it is easy to understand. Once you are comfortable with –ar, move on to –stylize.
Can I use multiple parameters in one prompt?
Yes, you can stack as many as you want. Just separate them with spaces. For example: /imagine a dragon –ar 16:9 –stylize 500 –chaos 20. Keep in mind that more parameters mean more constraints, so use them thoughtfully.
How do I make Midjourney generate more realistic images?
Use –style raw to reduce the default beautification. Also, keep –stylize low. High stylize values push Midjourney toward artistic interpretation, which can make images look less realistic.
What does –chaos actually do?
Chaos controls variety in your initial grid of four images. At –chaos 0, all four images are very similar. At –chaos 100, they are wildly different. It is useful for brainstorming but not for refinement.
Is there a way to get consistent characters across multiple images?
Consistency is one of Midjourney’s biggest challenges. You can use –seed to lock the composition, and you can use image prompts with high –iw values. However, perfect character consistency is still difficult. Many users combine Midjourney with other tools for this purpose.
What is the difference between –v 5 and –v 6?
Each version has its own strengths. V6 tends to produce more detailed and coherent images, especially for complex scenes. V5 has a distinct aesthetic that some users prefer for certain styles. We recommend experimenting with both and seeing which fits your needs.
Do parameters cost extra?
Parameters do not cost extra credits on their own. However, some parameters affect rendering time. For example, –quality 1 takes longer than –quality 0.25. Longer renders use more GPU minutes, which can deplete your fast hours faster.
