What is the best image size for Instagram?

Instagram recommends 1080x1080 pixels for square posts, 1080x1350 for portrait posts, and 1080x1920 for stories and reels. All should be under 30MB.

Will resizing reduce my photo quality?

If your original photo is larger than 1080px, resizing down preserves quality perfectly. Instagram itself compresses images, so uploading at exactly 1080px width gives the best results.

What aspect ratios does Instagram support?

Instagram supports 1:1 (square), 4:5 (portrait), and 1.91:1 (landscape) for feed posts, and 9:16 for stories and reels.
