Best Settings for Instagram Uploads (2026)
Instagram is notoriously aggressive with compression. Use these exact dimensions to prevent your photos from looking blurry or pixelated.
The Golden Rules of Instagram Sizes
Square Post (1:1)
1080 x 1080px
The classic format. Works universally.
Portrait Post (4:5)
1080 x 1350px
Takes up more feed space = more engagement.
Stories & Reels (9:16)
1080 x 1920px
Full screen mobile experience.
Landscape (1.91:1)
1080 x 566px
Not recommended (too small on screen).
Why Do My Photos Look Blurry?
If you upload an image wider than 1080px (like a 4000px raw photo from your camera), Instagram will brutally compress it down, often ruining the quality. If you upload something smaller than 320px, they will stretch it up, making it pixelated.
The Fix: Resize your image to exactly 1080px width before you upload. This enables you to control the quality yourself, using superior compression algorithms that preserve detail.
Understanding Instagram's Compression
Instagram uses aggressive JPEG compression to keep their servers fast and bandwidth low. Here's what happens to your photos:
- Automatic resizing: Images are scaled to max 1080px width
- Heavy compression: Typically 50-70 quality JPEG equivalent
- Color profile conversion: Everything becomes sRGB
- Metadata stripping: EXIF data is removed (including location)
By pre-optimizing at 1080px with quality 85-90%, your image only gets compressed once instead of suffering double-compression.
Pro Tip: Use sRGB Color Profile
Export your images in sRGB color profile before uploading. If you use Adobe RGB or ProPhoto RGB, Instagram will convert them—sometimes with unexpected color shifts.
Carousel Post Specifications
For carousel posts (multiple images), all images should be the same aspect ratio:
- Up to 10 slides: Mix photos and videos
- Consistent ratio: First image sets the ratio for all slides
- Recommended: Use 1080x1350 (4:5 portrait) for maximum screen presence
- Videos: Keep under 60 seconds per slide
Profile Picture & Thumbnails
Additional sizes you might need:
- Profile picture: 320 x 320px (displays at 110px on mobile)
- Story highlight covers: 161 x 161px
- Feed thumbnail: 161 x 161px (center of image is most visible)
Feed Preview and Cropping
Instagram's feed grid shows center-cropped squares of your posts. If you're using portrait (4:5) images, plan your composition knowing that the top and bottom will be hidden in the grid view.
- Keep important elements centered: The middle 1080x1080px area is always visible
- Avoid text at edges: It may get cropped in grid view
- Consider your grid aesthetic: Preview how posts look together
File Formats
Instagram converts everything to JPG. We recommend uploading high-quality JPGs to begin with to minimize double-compression artifacts. PNGs are okay for graphics but will be converted, potentially losing some sharpness.
