Instagram Feed video ad specs
Meta's Ads Guide entry for Instagram Feed video lists a 9:16 ratio (1% tolerance) at 1080 x 1920 pixels, MP4, MOV or GIF up to 4 GB, and 1 second to 60 minutes. Primary text is 125 characters, with up to 30 hashtags. The Facebook Feed entry recommends 4:5 instead, so check both before reusing a file.

Two Meta guides, two ratios
The Instagram Feed entry lists 9:16, while Meta's Facebook Feed entry recommends 4:5 at 1440 x 1800. If you run one asset across both feeds with Advantage+ placements, Meta will fit it to each surface, which can mean cropping. Building a 4:5 feed cut and a separate 9:16 vertical cut keeps you in control of what gets cut off.
We report what each guide states rather than resolving the difference ourselves. Meta updates these pages, so check the live entry when you build.
Writing for the Instagram feed
- Primary text over 125 characters is truncated, so lead with the claim.
- Hashtags are allowed (up to 30) but rarely help a paid post. Use them only where they add meaning.
- Captions and sound are optional but recommended; most feed viewing starts muted.
