We have a 2200 character limit on captions for ads targeting Instagram only, and return an error if you try to create this ad. If an ad targets both Instagram and Facebook and is over this limit, your request to create an ad succeeds, but we do not deliver it on Instagram.

Image and Video Requirements

Aspect Ratio

Instagram’s recommended aspect ratio for both image and video in Instagram stream is 1:1. We recommend square images and videos to utilize the maximum area on mobile devices. Instagram stream also supports images and videos with:

1.91:1 aspect ratio

4:5 aspect ratio

any aspect ratios in between 1.91:1 and 4:5

Size

We require all images and videos to have at least a 600px width, independent of the ad’s placement. However, our recommended numbers for images can change by placement:

Placement	Image Size Recommendation
Instagram	640px width or larger
Facebook	1080px by 1080px or larger

If you run Advantage+ catalog ads, product images specified in product feeds must be at least 600px or more in both width and height.

Video Length

Videos need to have between 3 and 60 seconds. A video plays in an endless loop on Instagram but only once on Facebook.

Video Thumbnail

video_data requires a thumbnail image. That image must have the same aspect ratio as the video, with a width of at least 600px.

Video File Size

The video file size cannot be over 2.3GB. After uploaded to Facebook and compressed, it cannot be larger than an internal limit. To see whether video file works as an Instagram ad, you should upload it first, and to use this API call to check the is_instagram_eligible boolean value:

curl -G \
-d "access_token=<ACCESS_TOKEN>"\
-d "fields=is_instagram_eligible"\
"https://graph.facebook.com/<API_VERSION>/<VIDEO_ID>"

The response looks like this if your video is not eligible:

{
  "is_instagram_eligible": false,
  "id": "<VIDEO_ID>"
}

Cropping

Videos cannot be cropped, but images can. The following information is only valid for images.

The cropping behavior depends on whether you send us a cropping spec. For Facebook placements, you can also use use_flexible_image_aspect_ratio.

If you provide a 100x100 cropping spec in link_data:

We use that for cropping for both Instagram and Facebook placements.

If an image is wider than 1.91:1, Instagram crops an ad to 1.91:1.

If you do not provide a cropping spec:

If an image is taller than 4:5 without a cropping spec, Instagram crops it to 4:5.

Additional Images

We usually deliver the default image specified by image_url, but you can delivery additonal_image_urls if you set additional_image_index in the ad template creative. To preview Advantage+ catalog ads using additional_image_index, you must pass the entire object_story_spec to the /generatepreviews endpoint. You cannot only pass object_story_id.

If a product has an image that is too small for Instagram, you do not see any errors when you create ads, but this ad is not delivered by Instagram Advantage+ catalog ads.

Instagram Story Ads

Image and Video Requirements

Aspect Ratio

For Instagram Stories, we recommend an aspect ratio for both image and video of 9:16. Instagram Stories also supports images and videos with:

4:5 portrait

Any aspect ratios in 1.91:1 and 4:5

For Carousel ads on Instagram Stories, check our Carousel Ads section.

Size

The minimum image or video width is 600px.

Cropping

Videos cannot be cropped, so you should provide videos between 1.91:1 and 4:5 or 9: 16 and taller.

Images can be cropped. You can use image cropping specs for image ads on Instagram Stories using 90x160, 100x100 and 191x100 crop keys:

If an image is wider than 1.91:1 and you provide no crop spec, we crop your image to 1.91:1.

If an image ratio is between 4:5 to 9:16 and you do not provide a cropping spec, we crop it to 4:5.
