Instagram Image Size Guide 2026 (Every Format & Dimension)
The complete Instagram image size guide for 2026: feed posts (1080×1350), Reels and Stories (1080×1920), carousels, profile photos, plus formats and why photos look blurry.
The ideal Instagram image size in 2026 is 1080 × 1350 pixels for feed posts (a 4:5 portrait), because it takes up the most screen space and gets more reach than square or landscape. But every format — Reels, Stories, profile, carousels — has its own ideal dimensions. Here's the complete, up-to-date Instagram size cheat sheet so your content never uploads blurry or cropped.
TL;DR. Use 1080 × 1350 (4:5 portrait) for feed posts, 1080 × 1920 (9:16) for Reels and Stories, 1080 × 1080 (1:1) for square posts, and a 320 × 320 profile photo. Always export at 1080px wide, keep files in JPG/PNG (photos) or MP4/MOV (video), and leave safe margins so text isn't cut off by the UI.

What is the best Instagram post size?
For feed posts, 1080 × 1350 (4:5 portrait) is the winner. It occupies more vertical space in the feed than a square, which means more screen attention and typically more reach. Square (1:1) still works and is safe for grids; landscape (1.91:1) takes the least space and is generally the weakest choice for engagement.
What size are Instagram Reels and Stories?
Both use full-screen vertical 1080 × 1920 (9:16). Keep important text and your logo in the center "safe zone" — roughly the middle 60% — because captions, the username, and action buttons cover the top and bottom edges. For length specs, see how long Instagram Reels can be.
What about carousel and grid sizing?
- Keep every carousel slide the same ratio (4:5 is ideal) so they don't get auto-cropped inconsistently.
- For seamless "panorama" carousels, design on a wide canvas and slice into 1080 × 1350 panels.
- Your grid thumbnails are square previews — keep key subjects centered so they look good both in-feed and on the profile grid.
What file format and quality should I use?
- Photos: JPG or PNG, exported at 1080px wide.
- Video: MP4 or MOV, up to 4GB.
- Resolution: always start at 1080px wide; uploading larger gets compressed, smaller looks blurry.
- Color: sRGB to avoid washed-out uploads.
Why do my Instagram photos look blurry or cropped?
The usual culprits:
- Wrong aspect ratio, so Instagram crops it.
- Exporting below 1080px wide (Instagram upscales = blur).
- Important text near the edges that the UI covers.
- Heavy compression from re-saving an already-compressed image.
Fix: design at the exact dimensions above, export fresh at 1080px, and keep text centered.
Stop resizing by hand
Manually cropping every photo and Reel to the right ratio is busywork — and easy to get wrong. WowPostio AI generates images and Reels already sized correctly for each Instagram format (4:5 feed, 9:16 Reels/Stories), so nothing uploads cropped or blurry.

Frequently asked questions
What is the best Instagram post size in 2026?
For feed posts, 1080 × 1350 pixels (4:5 portrait) is best because it fills more of the screen than square or landscape, which usually means more reach. Square (1080 × 1080) is a safe alternative; landscape takes the least space and is the weakest for engagement.
What size are Instagram Reels and Stories?
Both use a vertical 1080 × 1920 pixels (9:16) full-screen format. Keep important text and your logo in the center safe zone, since captions, the username, and buttons cover the top and bottom edges.
Why do my Instagram photos look blurry?
Usually because the image was exported below 1080px wide (Instagram upscales it), saved in the wrong aspect ratio and cropped, or heavily re-compressed. Export fresh at 1080px wide in sRGB at the correct ratio to fix it.
What file format should I use for Instagram?
Use JPG or PNG for photos (exported at 1080px wide) and MP4 or MOV for video (up to 4GB). Always start at 1080px wide and use the sRGB color profile to avoid blur and washed-out colors.
