Instagram has different image specs per format. Feed posts can be 1:1 square (1080x1080), 4:5 portrait (1080x1350 - takes maximum feed real estate), or 1.91:1 landscape (1080x566). Stories and Reels use 9:16 (1080x1920). Resize once for any of these with the preset; tweak with a manual crop if needed.
When to use this
Resize for: Instagram feed posts, Stories, Reels covers, Highlights covers, IGTV cover images (legacy), profile pictures, IG ads, IG Shopping product images. Same image, multiple formats - faster than doing each manually in Photoshop / Canva.
Frequently Asked Questions
What's the best image size for Instagram feed?
Portrait 4:5 (1080x1350) takes the most vertical space in the feed without being cropped, so engagement rates are typically higher than square (1:1) and landscape (1.91:1). Square is the safe default that crops well into the profile grid.
Does Instagram compress my images?
Yes - Instagram re-encodes everything you upload to its own JPEG quality (~70-80%). Uploading at higher resolution doesn't help; we recommend matching exactly the spec (1080 wide for square/portrait, 1920 high for Stories) to avoid double-compression artifacts.
