What are the correct image sizes for Instagram?

Instagram supports several image dimensions: Square Post is 1080x1080 pixels, Portrait Post is 1080x1350 pixels (best for feed engagement), Landscape Post is 1080x566 pixels, Story/Reels is 1080x1920 pixels, and Profile Picture is 320x320 pixels (displayed at 110x110).

What is the best image size for Instagram feed posts?

The portrait format (1080x1350 pixels, 4:5 ratio) takes up the most screen space in the feed, which typically leads to higher engagement. Square (1080x1080) is the classic Instagram format and works well for product photos and graphics.

What resolution should Instagram Stories be?

Instagram Stories should be 1080x1920 pixels (9:16 ratio). This fills the entire phone screen. If your image is a different ratio, use the Fill mode to crop it to fit, or use Fit mode to add bars and show the full image.

Does Instagram compress uploaded images?

Yes, Instagram compresses all uploaded images. To minimize quality loss, upload images at exactly the recommended dimensions (e.g., 1080x1080 for square posts) and in JPG format. This tool resizes to the exact dimensions Instagram expects.

What's the difference between Fill and Fit modes?

Fill (Crop) mode scales and crops your image to exactly fill the target dimensions — parts of the image may be cut off. Fit (Letterbox) mode scales the image to fit inside the dimensions while showing the entire image, adding white bars if needed.
