Aspect ratio parameter in Midjourney explained (with examples)

This great Twitter thread is worth to bookmark. It explains aspect ratios in Midjourney in depth. Make sure you give this person a follow!

The aspect ratio is one of the most powerful parameters when crafting a Midjourney prompt.

It plays a critical role in the composition, shape, and aesthetic of the image

Let's look at some examples and discuss🧵👇 (1/10)

--ar 1:1

The default aspect ratio (ar) in Midjourney is 1:1 or "--ar 1:1".

An ar of 1:1 is the classic square image. It is ideal for social media profile pics, icons, and logos.

--ar 16:9

This is the standard "wide-screen' ratio.

iPhone pictures and videos use an aspect ratio of 16:9.
It is typically used for presentations, animations, and videos. It is also Youtube's most common aspect ratio.

--ar 3:1 & 4:1

Do you like the 3 image stories that creators have been making lately? One way to make them is with a greater width to height ratio.

Wider aspect ratios are for landscape images when you want to show a broad horizontal expanse, such as panorama images.

--ar 1:3

The vertical champion!

This aspect ratio works great for tall generations, such as half- or full-body generations.

It also works great for generating stacked items like books or desserts.

--ar 9:16

One of the most popular aspect ratios for TikTok, Youtube shorts, and Instagram reels.

This aspect ratio provides greater height to your generation, while keeping the output more stable than --ar 1:3, which is an experimental aspect ratio.

--ar 3:2 & --ar 7:4

These aspect ratios are typically used for film photography, portraits, and art prints.

These are my personal favorite aspect ratios for content creation.

--ar 4:5

An aspect ratio of 4:5 is another very popular ar for generating portraits.

You are probably quite familiar with this aspect ratio because it is used for Instagram posts!

--ar 16:10

This aspect ratio is the standard adopted by Apple for their MacBooks and Microsoft for Surface tablets, which make it great for generating wallpapers.
