How To Solve Midjourney Aspect Ratio Not Working Problem

Are you having trouble making images look the way you want them to while using aspect ratio in Midjourney? There are several reasons why this might be happening.


In this article, I will explain seven things that you might be doing wrong that cause problems with the image aspect ratio.

I will also tell you how to solve these problems and make sure you get the dimensions you want.

What is aspect ratio?

Aspect ratio refers to the relationship between the width and height of an image, video, or other display media. It is shown by two numbers separated by a colon, such as 16:9 or 4:3.

The first number represents the width, and the second number tells you the height in ratio.
It determines the shape and size of pictures.

Meaning that aspect ratio affects how images look on different devices. For example, wider ratios like 16:9 are used for landscape, while 9:16 was more commonly used for portrait images.



Why is midjourney aspect ratio v5 not working?

Midjourney is a software program on Discord that generates images. By default, the images it makes are square, with an aspect ratio of 1:1.

However, you can create images with any dimensions using this tool.

Sometimes, though, you might get an error message when you try to make images with custom aspect ratios in Midjourney.

Here are seven possible reasons for this error and how to fix them:



You are using the wrong version

Versions 1 to 3 of Midjourney do not support custom aspect ratios. Version 4 allows aspect ratios between 1:2 to 2:1.

However, in version 5 and above, you can use any aspect ratio you want. So, check your setting to make sure you are using Midjourney version 5 or above.


The prompt format is wrong

To create custom aspect ratios in Midjourney, you need to use specific parameters, like “–aspect width:height” or “–ar width:height”.

For example, "--aspect 9:16" or "--ar 9:16".

So, make sure you spell everything correctly and use a colon instead of a semicolon.


There is a space in your prompt

This is a common mistake that causes issues with aspect ratios for many people. You want to make sure there is only one space in the parameter format, which is after the “–ar” or “–aspect” and before the values.

For example, don't write it like this: "-- ar 16:9" or "--aspect 16 : 9".


You added a comma at the end

If you add a comma at the end of the aspect ratio parameter, Midjourney might show an error message or ignore it completely.

So, there should be no comma at the end of your prompt when using a custom aspect ratio.

For example, don't write it like this: --ar 3:2, or --aspect 2:1,


You used an image as a prompt

In Midjourney, if you include an image link in your prompt, it will copy the aspect ratio of that image.

This means that if you use a square image but want to create a landscape image, the program will get confused.

Midjourney will ignore your custom aspect ratio parameter; or it fills the extra space with color.

Sometimes, it stretches out or compress the image in an attempt to fit your new aspect ratio prompt.

Wrong placement of parameter

When using a custom aspect ratio in Midjourney, you must add it at the end of your prompt. It should not be at the beginning or in the middle.

You should instead describe the image you want, and then add the aspect ratio.

Also, you can use the aspect ratio with other parameters at the end of the prompt. See prompt example image below:

Uncommon image dimensions

Midjourney was trained on images made by humans, so it works best with common aspect ratios. If you try to create an image with unique dimension, you might encounter problems.

For example, 16:9 is a very common aspect ratio for videos. But using 200:2 as an aspect ratio might not work.

According to Midjourney documentation, any aspect ratio greater than 2:1 is experimental and might give unpredictable results.
