What is the best Instagram post size in 2026?

1080×1350 pixels (4:5 portrait) is the recommended Instagram feed post size in 2026. It takes up the most vertical screen space in the feed, which translates to roughly 20% more visibility than a 1:1 square post.

What is the correct Instagram Story size?

Instagram Stories and Reels are 1080×1920 pixels (9:16 vertical). Keep important text and faces inside the central 1080×1420 safe zone — Instagram overlays the username, captions, and reaction UI at the top and bottom.

What size should an Instagram carousel be?

Use 1080×1350 (4:5) for the entire carousel, and keep every slide the same dimensions. Mixing aspect ratios inside one carousel forces Instagram to crop or letterbox slides inconsistently.

Does Instagram still support landscape posts?

Yes — 1080×566 (1.91:1) landscape is still supported, but it takes up the least feed real estate and consistently underperforms 4:5 portrait posts on engagement.

What file format should I upload to Instagram?

JPG for photos, PNG for graphics with text or logos. Keep files under 30 MB. Instagram re-encodes everything to JPG, so uploading already-compressed JPGs can stack compression artifacts — start from the highest-quality source you have.

4:5

Feed Post (Portrait)

Recommended

1,080 × 1,3504:5 · Instagram

The highest-performing feed format in 2026. Maximum vertical space without being cropped.

1:1

Feed Post (Square)

1,080 × 1,0801:1 · Instagram

Classic Instagram square. Safe choice when content needs to work as both a feed post and a profile-grid thumbnail.

1.91:1

Feed Post (Landscape)

1,080 × 5661.91:1 · Instagram

Smallest feed footprint. Best for repurposing 16:9 video stills or landscape photography.

9:16

Story / Reel

Recommended

1,080 × 1,9209:16 · Instagram

Full-bleed vertical. Keep key text inside the central 1080×1420 area so it isn't covered by the UI.

4:5

Carousel Slide

1,080 × 1,3504:5 · Instagram

Use the same ratio across every slide. Mixing ratios forces cropping.

1:1

Profile Picture

320 × 3201:1 · Instagram

Upload at 320×320 even though it renders smaller — Instagram uses the larger version on profile-view.
