The Ultimate Guide to Instagram Image Sizes in 2024
Stop Instagram from cropping your photos. Learn the exact dimensions for posts, stories, and reels to maximize engagement.
Instagram's algorithm favors high-quality images that occupy the maximum amount of screen real estate. If you upload an image with the wrong aspect ratio, Instagram will force a crop, potentially ruining your composition or blurring your photo through aggressive compression.
1. The Portrait Post (Recommended)
The 4:5 portrait ratio is the undisputed king of the Instagram feed. Because it is taller than a square, it takes up more vertical space on a smartphone screen. This forces users to scroll further to bypass your post, naturally increasing your engagement time.
- Dimensions: 1080 x 1350 pixels
- Aspect Ratio: 4:5
- Tool: Crop to Instagram Portrait
2. The Classic Square
While portrait posts perform better in the feed, the 1:1 square is how your images will be displayed on your profile grid. Many brands and artists prefer to upload perfect squares to maintain absolute control over their profile aesthetic.
- Dimensions: 1080 x 1080 pixels
- Aspect Ratio: 1:1
- Tool: Crop to Instagram Square
3. Stories and Reels
Instagram Stories and Reels demand full-screen vertical content. If you upload a horizontal video or square photo to your story, Instagram will generate ugly background bars to fill the empty space.
- Dimensions: 1080 x 1920 pixels
- Aspect Ratio: 9:16
- Pro Tip: Keep text away from the bottom 20% of the screen so it isn't covered by captions.
Why do my photos look blurry?
If you upload a massive 4K image directly from your DSLR camera, Instagram applies a brutal compression algorithm to shrink it for mobile delivery. To prevent this, always pre-compress your images to under 1MB using an Image Compressor before uploading.
