Selecting the Instagram Feed placement will allow members of your audience to see your ad within their Instagram app feed. 


  • File type: jpg or png

  • Maximum file size: 30MB

  • Recommended resolution: highest possible

  • Minimum Image Width in Pixels : 500

  • Aspect Ratio Tolerance : 1%

  • Minimum Image Ratio : 4:5

  • Maximum Image Ratio : 1.91:1

Denim recommends the image ratio of 4:5 for ads being displayed on Feeds. 


These full screen vertical ads appear between Instagram user stories. Photo stories are visible for 5 seconds or until the user swipes out of the story.

Best practice: keep roughly 14% (250 pixels) of the top and bottom of the image free from text and logos. These two areas house the profile icon and the call-to-action. This means, if your image is 1080px x 1920px, ensure key elements appear within a 1080px x 1420px area.


  • Image ratios: 9:16 and 16:9 to 4:5

  • Minimum Image Width in Pixels : 500

  • Aspect Ratio Tolerance : 1%

  • Maximum Image Ratio : 9:16

Because most consumers hold their phones in portrait orientation, Denim recommends an image ratio of 9:16 for ads being displayed on Stories.
