# 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](/using-ideogram/generation-settings/available-models.md) for version-specific capabilities.

To select a specific aspect ratio:

1. Select the [Prompt Box](/using-ideogram/ui-overview/ui-components/prompt-box.md) to expand it (if not already expanded) and display the generation settings.
2. Select **Aspect Ratio** (displayed as the actual aspect ratio, such as <kbd>**1:1**</kbd>) to view the available formats.

## Default Aspect Ratios and Sizes

The table below shows the available default aspect ratios for each model and the size of the generated images they produce.

* <kbd>**9:16**</kbd> *–* Ideal for vertical display on smartphones and some social networking sites.
* <kbd>**10:16**</kbd> *–* Portrait format originally used in early Ideogram versions 0.1 and 0.2.
* <kbd>**2:3**</kbd> *–* Portrait format mainly used in digital photography and poster printing.
* <kbd>**3:4**</kbd> *–* Portrait aspect ratio mainly used in film photography.
* <kbd>**4:5**</kbd> *–* Common portrait ratio used in film photography.

### Square

* <kbd>**1:1**</kbd> *–* A square format, often used in social media and image sites.

### Horizontal

* <kbd>**5:4**</kbd> *–* Landscape aspect ratio mainly used in film photography.

## Custom Aspect Ratios

You can create a custom aspect ratio when the default options don’t meet your needs.

In versions 2.0 and later, users on the **Basic Plan** or higher can use custom aspect ratios in two ways:

1. Use the **Slider** under the *aspect ratio preview* to access continuous ratio values beyond the presets.
2. Select **Custom** to manually enter the desired aspect ratio or pixel dimensions. The interface automatically adjusts to the nearest supported ratio between <kbd>**1:3**</kbd> and <kbd>**3:1**</kbd>.

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.ideogram.ai/using-ideogram/generation-settings/aspect-ratio-and-dimensions.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
