Instagram Photo Dimensions & Aspect Ratios (2026)

Feed Photos (Single Post)

Instagram supports three main feed aspect ratios:

• **Square (1:1)** — 1080×1080 px. The classic Instagram look. Safe for any crop.
• **Portrait (4:5)** — 1080×1350 px. Takes the most screen space on mobile feeds — best engagement.
• **Landscape (1.91:1)** — 1080×566 px. Smallest visual footprint; use only when content demands it.

Recommended: portrait 4:5 for almost all photos. Largest preview area in feed without being cropped.

Carousel Posts (Multi-Photo)

All photos in a carousel must use the same aspect ratio. If you mix sizes, Instagram crops to the first photo's ratio.

• Up to 10 photos / videos per post
• Each at 1080 width
• Use the 4:5 portrait ratio for best mobile experience

Pro tip: design a "swipe to see more" hook in the first image — it drives more swipe-throughs and signals engagement to the algorithm.

Stories & Reels

• **Stories**: 1080×1920 px (9:16 vertical). Safe zone: keep important content within the center 1080×1670 area (top 250px and bottom 250px get covered by UI).
• **Reels cover**: 1080×1920 px, same as the Reel itself.
• **Reel feed thumbnail (in grid view)**: cropped to 1080×1350 (4:5). Design your cover so the important visual sits in the center.

Profile & Highlights

• **Profile picture**: uploaded at 320×320, displayed in a circle. Use 1080×1080 for crispness on retina.
• **Highlight cover**: 1080×1920 (9:16) but only the center circle (1080×1080) is visible. Important visual must fit in that circle.
• **Profile grid preview**: 1080×1080 (the center square of any post).

File Format & Quality

• **Format**: JPEG (preferred) or PNG. WebP is supported but JPEG renders most consistently.
• **Max file size**: 30 MB per image.
• **Color profile**: sRGB. Other profiles get auto-converted with noticeable shift.
• **Compression**: Instagram applies its own compression. Upload at 1080 width minimum — anything smaller will look worse after re-compression.

Common Mistakes to Avoid

• Uploading 1920×1920 thinking bigger is better. Instagram down-scales to 1080. Larger files just take longer to upload.
• Mixing aspect ratios in carousels (auto-cropped to first photo).
• Putting text near the top/bottom of Story photos (covered by UI).
• Using PNG for photos (way larger file, no visual benefit on Instagram).
• Forgetting Reels feed thumbnails are cropped — design for both the full 9:16 and the 4:5 crop.
