This article is everything you must know about the Unreal Engine aspect ratio! Unreal Engine is a powerful game development tool used by developers worldwide.
One important aspect of Unreal Engine is the aspect ratio, which affects how a game is displayed on different screen sizes and resolutions. In this guide, we will explore everything you need to know about the Unreal Engine aspect ratio, including how to set it up and enforce a user-defined aspect ratio.

What Is The Unreal Engine Aspect Ratio?

The aspect ratio in the Unreal Engine is the ratio of the width of the game viewport (the area where the game is displayed on the screen) to its height. It defines the proportions of the game’s visuals and affects how the game is displayed on different screen sizes and resolutions.
By default, the aspect ratio in the Unreal Engine is 16:9, which is the standard widescreen aspect ratio used in most modern devices, such as TVs, monitors, and smartphones. However, the engine allows developers to customize the aspect ratio to suit their specific needs.
To change the aspect ratio in the Unreal Engine, you can go to the project settings and navigate to the “General Settings” tab. From there, you can adjust the aspect ratio by changing the values in the “Default Viewport Settings” section under the “Game Viewport” category.

How To Get The Current Camera Aspect Ratio

In Unreal Engine, you can get the current camera aspect ratio by accessing the camera component attached to your player character or any other object in your level. Here’s an example of how to do it using Blueprint:
- First, select the camera component you want to get the aspect ratio for.
- Right-click in the Blueprint Graph and search for “Get Aspect Ratio”. Select the “Get Camera Aspect Ratio.”
- Connect the output pin of the camera component to the input pin of the “Get Camera Aspect Ratio” function.
- The output pin of the “Get Camera Aspect Ratio” function will give you the current aspect ratio of the camera.
- You can then use this value in your Blueprint logic to adjust other elements in your game, such as the user interface or other visual elements, to match the aspect ratio of the camera.
Alternatively, if you prefer to use C++ to get the current camera aspect ratio, you can access the camera component and call the “GetAspectRatio()” function, which returns a float representing the current aspect ratio of the camera.

How To Enforce A User-Defined Aspect Ratio

Enforcing a user-defined aspect ratio in Unreal Engine can be done by setting the desired aspect ratio in the project settings and adjusting the viewport settings of the camera to match it. You can follow these steps:
- Open the project settings by going to the Edit menu and selecting Project Settings.
- In the Project Settings window, navigate to the General settings category and select the section labeled “Default Viewport”.
- Under the “Default Viewport” section, locate the fields labeled “Desired Width” and “Desired Height” and set them to the values representing your desired aspect ratio. For example, if you want a 4:3 aspect ratio, set the width to 4 and the height to 3.
- Save. Then close the Project Settings window.
- Next, select the camera in your level for which you want to enforce the aspect ratio.
- In the Details panel, scroll down to the “Camera” category and locate the “Post Process Settings” section.
- Expand the “Post Process Settings” section. Then locate the “Aspect Ratio” field.
- Set the “Aspect Ratio” field to “Custom” and enter the same values you used in step 3 for the desired width and height.
- Save the changes and run your game to test the new aspect ratio. The camera viewport should now be constrained to the aspect ratio you defined.

F.A.Q.S
What Aspect Ratio Is An Unreal Engine Camera?
The letterbox aspect ratio is 2.35:1 by default.
What Is The 2.35 1 Aspect Ratio?
The 2.35:1 aspect ratio is a widescreen aspect ratio commonly used in the film industry. It is also known as the CinemaScope aspect ratio or anamorphic widescreen. The aspect ratio is defined as a horizontal-to-vertical ratio of 2.35 units to 1 unit, meaning the image is 2.35 times wider than it is tall.
What Are The 4 Landscape Sizes In Unreal Engine?
In Unreal Engine, there are four landscape sizes available for creating terrain on a level. These landscape sizes are 63×63, 127×127, 255×255, and 513×513.
Each landscape size has its own benefits and drawbacks, depending on the specific needs of a project. Game developers can choose the landscape size that best suits their project requirements and hardware capabilities.
What Is The Size Of The Landscape In Unreal Engine 5?
In Unreal Engine 5, the size of the landscape has significantly increased compared to previous versions of the engine.
The new maximum size for a landscape in Unreal Engine 5 is 100 square miles (approximately 259 square kilometers), which is a significant increase from the maximum size of 25 square miles (approximately 64 square kilometers) in Unreal Engine 4.
What Aspect Ratio Is VR?
Virtual Reality (VR) does not have a fixed aspect ratio, as it depends on the specific VR system and device being used. VR typically involves using a headset with two displays, one for each eye, which is positioned close to the user’s eyes to create an immersive 3D experience.
Conclusion
Understanding the Unreal Engine aspect ratio is crucial for game developers who want to ensure their game is displayed correctly on different devices. By setting up and enforcing a user-defined aspect ratio, developers can create a consistent visual experience for their players.
With the knowledge gained from this guide, developers can confidently incorporate aspect ratio considerations into their game development process. For more articles about Unreal Engine, visit Animost!
