How to determine the size of the images in your feed

When you customize your In-feed ad, it's useful to know the size of the images in your feed so you can set your ad's image size to match. If you don't know the size of your images, you can use your browser's developer tools to find their exact dimensions. For example, if you're using Google Chrome, you can use the inspect element tool in the Chrome DevTools.

To determine the size of an image using Chrome, follow these steps:

1. Open the page with your feed in Chrome.
2. Right-click the image whose size you want to know and select Inspect.
3. View your image's width and height displayed in the Chrome DevTools. (Note, the first number is always the width). If your image is not highlighted by default, click the inspect element button  and hover over the image.
