Frequently asked questions
What size is an Instagram post?
A square post is 1080 × 1080 pixels and a portrait post 1080 × 1350 pixels (4:5), the tallest format the feed shows. Stories and Reels are 1080 × 1920 (9:16).
Square or portrait?
Portrait takes more room in the feed, so it's usually the better pick for a product or an ad. Square is the safe choice for a grid that looks even.
