Instagram Image Size Cheat Sheet 2026

The standard Instagram post size is 1080x1080 pixels (1:1 square). Portrait posts at 1080x1350 (4:5) take up more feed space. Landscape posts at 1080x566 (1.91:1) are also supported but show smaller in the feed.

Instagram stories should be 1080x1920 pixels (9:16 aspect ratio). This fills the entire screen on most devices. Images smaller than this will be upscaled and may look blurry.

Instagram profile photos should be at least 320x320 pixels. The image is displayed as a circle at 110px in the feed and 150px on the profile page. Upload a higher resolution for the sharpest result.

Yes. Instagram applies JPEG compression to uploads. To minimize quality loss, use the intended aspect ratio, keep feed images around 1080px wide, avoid uploading previously compressed images, and start with high-quality source files.

Reel covers are 1080x1920 (9:16), the same as stories. However, they are cropped to a square (1:1) in the profile grid and to 9:16 in the Reels tab, so keep important content centered.

Instagram Reels should be 1080x1920 pixels (9:16 aspect ratio). The maximum file size is 250MB and maximum duration is 90 seconds. Use H.264 codec in MP4 container for best compatibility.

MP4 with H.264 video codec and AAC audio is the safest format for Instagram video types: Reels, feed videos, and stories. Keep the resolution at 1080px wide (1080x1920 for vertical, 1080x1350 for portrait feed). Instagram re-encodes uploads, so a clean H.264 source produces the best result.
