# 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](https://docs.ideogram.ai/using-ideogram/generation-settings/available-models) for version-specific capabilities.
To select a specific aspect ratio:
1. Select the [Prompt Box](https://docs.ideogram.ai/using-ideogram/ui-overview/ui-components/prompt-box) to expand it (if not already expanded) and display the generation settings.
2. Select **Aspect Ratio** (displayed as the actual aspect ratio, such as **1:1**) to view the available formats.
