Midjourney Aspect Ratio FAQs
Check out these Midjourney aspect ratio FAQs and get the answers to questions to help you learn more about this powerful parameter.
Also, you can change the aspect ratio for an image whether you are using the Midjourney website or Discord to enter your prompts.
An aspect ratio is the width-to-height proportion of your image. Midjourney uses this ratio to determine the overall shape, such as square (1:1) or widescreen (16:9).
Use the parameter –ar followed by the ratio.
For example: abstract painting –ar 16:9 or oil painting –ar 9:16
The 16:9 produces a widescreen image. The 9:16 creates a portrait layout.
The default aspect ratio is 1:1, which creates a square image.
Add –ar and the ratio in whole numbers with colon (:) between the numbers.
Example: cute monster –ar 4:5
See this article on understanding Midjourney aspect ratios.
Yes, the aspect ratio must fit within Midjourney’s constraints. Extremely wide or tall ratios might not work. Stick to common formats like 16:9 or 2:3 for easier results.
No. Midjourney doesn’t support decimals. Instead, use whole numbers to express the ratio—for instance, –ar 3:2 or –ar 9:16
Yes and no. The aspect ratio changes the image’s shape but not its resolution. Use a photo editing software to specify the resolution separately if quality is critical. You can find a great free photo editing software at Photopea.
Aspect ratios define image proportions. Resolution, set with parameters the width and height, defines actual pixel dimensions. Ensure they match for optimal results if you would need to edit the image.
Midjourney defaults to a square image with a 1:1 ratio unless you specify a different aspect ratio.
Yes, but rendering times may increase with extreme ratios. Wide formats like 32:9 are possible but can look distorted.
- Social Media Posts: Use 1:1 for Instagram or 4:5 for posts.
- Widescreen Displays: Use 16:9 for videos and presentations.
- Mobile Screens: Use 9:16 for portrait orientation.

Yes, previews reflect your chosen aspect ratio. If it looks off, double-check the –ar value.
Yes. But you need to use the permutation parameter to run multiple image sizes. To do this: list your options separated with commas (,) within curly braces ({ }) in your prompt. By doing this, you can create multiple versions of a prompt with different aspect ratios.
Example Prompt: beautiful sunset –ar {2:1, 16:9, 3:4}
Midjourney adjusts composition to fit the specified shape. This might crop details from an original image to maintain balance.
Ensure your aspect ratio is properly formatted.
- Example: –ar 16:9 not 16×9
Do not add it into your prompt.
- Example: beautiful sunset, make the image 16×9.
If problems persist, try common ratios like 1:1 or 4:3 to test.

No, you can experiment with as many as you want. Just tweak the –ar value for each prompt.
No, using the –ar parameter doesn’t increase credit usage. It’s considered part of the regular generation process.
