# 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 <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>**1:3**</kbd> – Very tall banner.
* <kbd>**1:2**</kbd> – Tall vertical format. Sometimes used in artworks or creative compositions. *Version 2.0 and higher.*
* <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.

### 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.
* <kbd>**4:3**</kbd> *–* Landscape format, used by old traditional standard definition television. Also used in film photography.

* <kbd>**2:1**</kbd> *–* Large banner. Commonly used for 360° equirectangular panoramas.
* <kbd>**3:1**</kbd> *–* Very large banner.

## 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>.
