How To Canvas Size In Obs

OBS, short for Open Broadcasting Software, is a highly adaptable and robust live streaming tool that offers a wide range of functions, including the option to modify your canvas dimensions. This feature is vital as it enables you to personalize the size of your stream output to suit your preferences and the platform you’re streaming on. Let’s explore the step-by-step process of adjusting the canvas size in OBS.

Step 1: Open OBS

Firstly, you need to open the OBS application. This could be either OBS Studio or Streamlabs OBS. The process is essentially the same for both versions.

Step 2: Navigate to Settings

Once the OBS is open, navigate to the ‘Settings’ option. This will open a new window where you can adjust various settings related to OBS.

Step 3: Go to Video Settings

Inside the settings window, select the ‘Video’ tab on the left side. This will reveal options related to video such as Base (Canvas) Resolution and Output (Scaled) Resolution.

Step 4: Adjusting the Canvas Size

In the ‘Base (Canvas) Resolution’ section, you can set the size of your canvas. This is typically the size of the screen that OBS captures. The default value is usually your screen resolution, but you can adjust it to your needs.

For example, if you want to set the canvas size to 1280×720, you would input it as shown below:

Base (Canvas) Resolution: 1280x720

Keep in mind, choosing a canvas size will depend on the platform you’re streaming on and your computer’s power.

Step 5: Apply the Changes

Once you have set your desired canvas size, click the ‘Apply’ button at the bottom of the settings window to save the changes. Now, your OBS canvas will be the size you set!


Adjusting canvas size in OBS is a straightforward process that allows you to customize your streaming setup to suit your needs. Whether you’re streaming games, tutorials or any other content, knowing how to set your canvas size correctly will ensure that your viewers have the best possible experience. Happy streaming!
