Follow the steps below to add extra custom sizes to your ad set. Note that this action can be performed from both the "Single" and "All" view modes:
From the "Single" view mode ad editor:
Click on the sizes dropdown in the toolbar.
The sizes that are currently added to the adset will display in a list. To add new ones, click on “Add size” in the dropdown.
Click on the “Add size” button to add your custom size.
Enter a name, width, and height, and click on “Add custom size”
💡 Good to know: Not all networks allow all custom sizes so before you add your custom size make sure your network supports it.
From the "All" view ad editor:
Once you are in the "All" view ad editor, click on the sizes dropdown menu:
The sizes that are currently added to the adset will display in a list. To add new ones, click on “Add size” in the dropdown.
Click on the “Add size” button to add your custom size.
Enter a name, width, and height, and click on “Add custom size”.
That's it!
Do you need to have the same size more than once in your ad set?
This is possible. Simply add the size you need as a custom size again. By default, when a size is added to an ad set, you can't select it again. However, you can manually add it as a "custom size" as many times as needed.
