Aspect ratio (AR) image ratio-ar

Use-aspect or-ar parameters to change the aspect ratio of the generated picture, that is, the aspect ratio, such as 4:3, 16:9. The width and height of a square image are equal, which is described by the aspect ratio of 1: 1. The picture can be 1000px 1000px, or 1500px 1500px, and the aspect ratio is still 1: 1.

The default aspect ratio of MidJourney is 1: 1.

Aspect parameter must be an integer. Using the aspect ratio of 139: 100 instead of 1.39: 1 will affect the shape and composition of the generated picture. When you zoom in, some aspect ratios may change slightly.

Different versions of Midjourney have different maximum aspect ratios.

The-ar parameter can accept any aspect ratio from 1: 1 (squared) to the maximum value of each model. However, in the process of image generation or enlargement, the final output result may be slightly modified. For example, using a hint of -ar 16: 9 (1.78) will create an image with an aspect ratio of 7:4 (1.75).

Quick example: vibrant California poppy -ar 5: 4

Commonly used half-way picture ratio is as follows:

-Aspect 1: 1 default aspect ratio

-Appearance 5: 4 general frames and printing scale

-Aspect 3.2 Common proportions in print photography

-The aspect ratio of 7: 4 is close to HDTV screen and smartphone screen.

The commonly used aspect ratios of Xiaohongshu are:
