Part 1. Common Midjourney Aspect Ratios

Midjourney defaults to a 1:1 aspect ratio, creating a square image. This is great for portraits or balanced compositions. But sometimes, this is not the best option. The true magic happens when you explore other Midjourney aspect ratios.

A Snapshot of Popular Midjourney Aspect Ratio

Square: 1:1 is the default Midjourney aspect ratio. It offers balanced compositions, social media compatibility, a timeless aesthetic, and easy cropping for future edits.

Landscape: Unleash your inner cinematographer with the wide-screen feel, perfect for capturing sweeping vistas. The classic 5:4 ratio offers a timeless elegance for general compositions. 3:2 is often chosen for print photography. 4:3 ratio is a favorite for older TVs and computer screens. 16:9 aspect ratio is the pick for widescreens. 7:4 aspect ratio aligns with HD TV screens and many smartphones. And 5:4 is widely used for framing and print.

Portraits: Elevate your portraits with the 2:3 ratio, emphasizing the subject's features. Don't be afraid to experiment with taller ratios to add a unique and artistic touch to your portraits. For example, 9:16 is perfect for mobile wallpapers, offering a sleek, elongated look that draws the viewer's eye down the image. 4:5 aspect ratio reminds of classic film photography, adding a touch of vintage charm and elegance to your portraits. And 3:4 ratio provides a more intimate and focused framing for your subject.

Part 2. How to Set the Aspect Ratio in Midjourney

1. Set Midjourney Aspect Ratio Using --aspect or --ar Command

If you’re about to create an image, simply use the --aspect or --ar parameter within your prompt to set the aspect ratio. It changes the width-to-height ratio of the generated image. It is typically expressed as two numbers separated by a colon, such as 7:4, 3:2 etc. For example, --ar 3:2 will generate an image with a width-to-height ratio of 3 to 2.

2. Set Midjourney Ratio Using Website Settings

The Midjourney website provides a convenient way to set a default aspect ratio that applies to all your prompts unless you override it. Use the Portrait button for a classic 3:4 ratio or the Landscape button for a wider 4:3 format. For more control, use the slider. Slide left for taller ratios (up to 1:2, great for portraits) or right for wider ones (up to 2:1, ideal for landscapes).

While the slider offers a range, it doesn’t suitable for all Midjourney dimensions. Fortunately, the --ar parameter within your prompt lets you set any aspect ratio imaginable!

Part 3. How to Change Aspect Ratio in Midjourney

1. Change Midjourney Image Size Using Zoom Out Feature

If you want to change the aspect ratio of an image that already have been generated in Midjourney, you can try the zoom out feature after upscaling. To upscale the image in Midjourney, select one of the image option from U1 to U4. Then Midjourney will generated an upscaled version of your selected image. And below the image, you can see some Zoom Out features, like Zoom Out 2x, Zoom Out 1.5x and Custom Zoom. Just choose the one that you desired.

For example, select the “Custom Zoom”option and it reveals a panel where you can define your desired aspect ratio. Set the zoom value to 1 using --zoom 1, which will maintain the original zoom level. Then define the Midjourney aspect ratio like --ar 3:2.

2. Utilize Pan Feature to Change Aspect Ratio of Midjourney

The Pan feature can also help Midjourney change aspect ratio. After upscaling your image, four arrows appear (up, down, left, right). Clicking one extends the image in that direction, letting you explore beyond the original frame. You can pan the image in a single direction or multiple direction according to your needs.

For example, here is the image adjusted from a 1:1 aspect ratio to 3:2 by panning leftward.
