Image ad specs 

Design recommendations from Facebook:

The image featured on your ad needs to look stunning, regardless of the device. To make your ads stand out on a busy feed, follow these tips from Facebook. Also, take note of the limitations placed on the amount of text allowed on an image:

  • File type: .jpg or .png
  • Image ratio: 1.91:1 to 4:5
  • Recommended resolution: There’s no restriction on the maximum resolution, so upload the highest resolution image available 
  • The text on an image should be kept below 20%. You can check if your ad image meets the 20% limit by using Facebook’s Text Overlay tool. An ad image with too much text is one of the 7 Deadly Sins That Kills Facebook Ads, committing one of them could stop a promising ad campaign in its tracks.
