Instagram Photo & Video Resolution Guide: Dimensions & Formats (2026)

Posting media in incorrect dimensions causes Instagram’s compression algorithms to aggressively crop, downscale, or blur your content.

Use this complete reference sheet to optimize your photos and videos before publishing.

1. Master Resolution & Dimension Table

Placement Format	Aspect Ratio	Optimal Resolution	Supported File Types	Max File Size
Feed Square	1:1	1080 x 1080 px	JPEG, PNG, WebP	30 MB
Feed Portrait (Recommended)	4:5	1080 x 1350 px	JPEG, PNG, WebP	30 MB
Feed Landscape	1.91:1	1080 x 566 px	JPEG, PNG, WebP	30 MB
Instagram Stories	9:16	1080 x 1920 px	MP4, MOV, JPEG	4 GB (video)
Instagram Reels	9:16	1080 x 1920 px	MP4, MOV (H.264)	4 GB
Profile Avatar	1:1 (Circle)	1080 x 1080 px (displays 320x320)	JPEG, PNG	10 MB

Keep Width at Exactly 1080px: Any wider (e.g., 4K 3840px) will be downscaled aggressively by Meta's ingest server.

Export in sRGB Color Profile: Using Adobe RGB or DCI-P3 can cause washed-out colors on mobile screens.

Use High-Bitrate H.264 Video: Aim for 15–25 Mbps bitrate at 30 or 60 fps for Reels.
