EVERY INSTAGRAM SIZE

Every Instagram photo size

The exact dimensions Instagram displays, so your photos never get cropped or compressed unexpectedly.

Square post

1080 x 1080 px

Aspect ratio 1:1. The safe default for mixed content.

Portrait post

1080 x 1350 px

Aspect ratio 4:5. Biggest feed footprint, usually the best choice.

Tall portrait post

1080 x 1440 px

Aspect ratio 3:4. Matches Instagram’s grid thumbnail exactly.

Landscape post

1080 x 566 px

Aspect ratio 1.91:1. Suits wide scenes, smallest feed footprint.

Story or Reel

1080 x 1920 px

Aspect ratio 9:16. Full screen format for Stories and Reels.

Profile picture

320 x 320 px

Aspect ratio 1:1. Displays as a circle, so center your subject.

GETTING IT RIGHT

Which size should you pick

Instagram crops or compresses anything that doesn’t match its display sizes. Here’s how to keep it in your control.

Why size matters

If your image doesn’t match a supported ratio, Instagram crops it automatically. If it’s much larger than needed, Instagram compresses it hard, which is where blurry posts come from.

Best size for feed posts

Portrait 4:5 takes up the most space as people scroll. Square 1:1 is the safe default, and landscape 1.91:1 suits wide scenes.

Grid thumbnails

Instagram’s profile grid now shows 3:4 rectangles. Upload natively at 1080×1440 to control that crop yourself instead of leaving it to Instagram.

Tips for sharp photos

Start from the highest resolution you have and keep the width at 1080px so Instagram doesn’t upscale it. Use JPEG for photos, a higher quality setting for graphics and text.

Frequently Asked Questions

Upload your photo, pick the Instagram format you need, crop and zoom to frame your shot, and download. The tool exports at the exact pixel dimensions Instagram displays, so nothing gets cropped or squashed when you post it.

Portrait posts are 1080 x 1350 pixels (4:5), square posts are 1080 x 1080 (1:1), and landscape posts are 1080 x 566 (1.91:1). Portrait 4:5 takes up the most space in the feed, which is why most accounts default to it.

Stories and Reels use the full screen 9:16 format at 1080 x 1920 pixels. Keep important text and faces away from the very top and bottom of the frame, where Instagram overlays the profile name and reply bar.

Instagram displays profile pictures at 320 x 320 pixels in a circle. Center your subject so nothing important gets clipped by the circular crop.

Instagram switched profile grid previews from squares to 3:4 rectangles. Your posts still display at their full ratio in the feed, but the grid thumbnail is cropped to 3:4, so keep faces and text centered vertically. You can also upload natively at 3:4 (1080 x 1440) to control that crop yourself.

No, not if you start from a reasonably sharp photo. It usually improves how the post looks, since uploading an oversized image forces Instagram to compress it with its own aggressive settings instead.

JPEG is the safe default for photos, smaller files, fast uploads, and no visible quality loss at a high quality setting. If your image has flat colors, text, or sharp edges, a higher quality export avoids compression artifacts.

Yes, completely free, no login, no watermark, no download limits.
