Aspect Ratio and Dimensions
Aspect Ratio controls the proportions of your generated images. Depending on the Ideogram model version, you can choose from different preset and custom ratio options. See Available Models for version-specific capabilities.
To select a specific aspect ratio:
Select the Prompt Box to expand it (if not already expanded) and display the generation settings.
Select Aspect Ratio (displayed as the actual aspect ratio, such as 1:1) to view the available formats.

Select Custom to manually enter the desired aspect ratio or pixel dimensions. The interface automatically adjusts to the nearest supported ratio between 1:3 and 3:1.
