How to change image aspect ratio in Midjourney

Do you want to create images in different aspect ratio in MidJourney? Many midjourney users have faced aspect ratio problem for a long time because MidJourney used to only make images in a 1:1 ratio.

The latest version of midjourney v6 provides much more freedom in aspect ratio. For example, suppose you want to create a wide landscape or a tall portrait, you can easily generate it by typing the appropriate aspect ratio. You can also tried weird aspect ratios.

So, how can we do this? This article will explain aspect ratio parameters and how you can generate images in different aspect ratios?

Importance of Aspect ratio?

Aspect ratio is the size parameter used both for image and video. It describes the relationship between an image’s width and height. It consists of two numbers separated by colon. First number shows the width , second shows the height. For example, If the image aspect ratio is 1:1 it means that the image has equal height and width forming a square. One type of aspect ratio is not suitable for all types of screens. Different screen and platforms have different type of aspect ratios.

Aspect ratio is the most powerful parameter in midjourney. It plays important role in image composition , shape and aesthetics. The aspect ratio selection depends on your intent. There are different types of images users generate in midjourney, whether it’s wallpaper, coloring book pages, illustrations, social media banners, etc.

Common types of aspect ratios including 3:2(portrait) , 1:1 default(square), 16:9(landscape), 1:1(square), 9:16(vertical). The default aspect ratio in midjourney is 1:1, so if you don’t specify any aspect ratio, it will generate in square .It will also generate in custom size, but in this case, you will need to specify the size in pixels.

Method to change the aspect ratio in midjourney?

There are three ways to change the aspect ratio of images in midjourney. Let’s look at all three methods.

Method 1 : Using —ar parameter

This is the most popular method for changing the aspect ratio and it gives the accurate result. When you generate the new image you can easily control the aspect ratio through prompt. The parameters are added at the end of the prompt, so you need to include them according to your requirements. You have to add –ar (double dash without spaces with ar) at the end of the prompt. Midjourney will generate the image in the ratio you specified instead of the default 1:1 ratio. This makes it easy to get the exact dimensions you want for your image.

Method 2 : Using Custom Zoom

If you’ve made an image but want to change its shape, using the same method might give you a different picture. For example, if you first made a rectangular image with a ratio of 16:9, and now you want a taller, narrower one with a ratio of 9:16, you can do this by custom zoom option. You will have an opportunity to change in a prompt. If you give the prompt again in the “imagine” option and change the aspect ratio at the end, a new image will be generated.

1- After generating the images, click on the custom zoom option from the menu below the image.

2- Here your image prompt will appear. Change the aspect ratio into another value.

How to Fix Aspect Ratio Not Working

Some times midjourney aspect ratio does not work and midjourney give invalid parameter message.

Do not type invalid ratio

Sometimes you might use an aspect ratio that MidJourney doesn’t understand. It’s best to use only the aspect ratios that MidJourney supports. Common ratios that midjourney supports are 9:16 , 16:9 , 2:1 , 3:2.

Check the Syntax

Make sure there is no mistake in your syntax of aspect ratio. You must add the space after the end of the prompt then add the attached double hyphen with ar. There is no case sensitive problem in ar. Do not use any other syntax such as ~~, __ .

Use latest versions

You must use the latest versions of midjourney. Older versions have limited functionality when it comes to aspect ratios. Currently midjourney version 6 is best for all aspect ratios.

Conclusion

Midjourney v6 provides you with higher resolutions and custom aspect ratios. Being consistent in a midjourney can be valuable to you. The aspect ratio is a tricky way to change from the images. It depends on you how you effectively used this feature to make it a good dimension. An aspect ratio is just a value used for making the correct dimensions.
