Image Sizes for Instagram, X (Twitter), and LinkedIn — 2026 Reference
Every social platform has its own pixel grid. Upload the wrong size and your post gets cropped, blurred, or letterboxed — at exactly the moment your message needs to land cleanly. This page documents the dimensions that actually work in 2026, and gives you a 10-second workflow to resize multiple images at once without uploading them anywhere.

Instagram supports 4 native aspect ratios. Outside of these the platform crops or letterboxes.
| Slot | Aspect | Pixel size (recommended) |
|---|---|---|
| Feed — square | 1:1 | 1080 × 1080 |
| Feed — portrait | 4:5 | 1080 × 1350 |
| Feed — landscape | 1.91:1 | 1080 × 566 |
| Story / Reel | 9:16 | 1080 × 1920 |
| Profile photo | 1:1 | 320 × 320 (displayed; upload 600+) |
Why 1080 px wide and not 2048? Instagram downsamples anything over 1080 px on the longest edge for feed posts. Uploading larger files wastes time and may trigger Instagram's own compression more aggressively than your own. Story/Reel is the exception — 1080×1920 is exactly what the player shows.
X (Twitter)
X has the most generous in-feed sizing as of 2026. Images display at their native ratio between 2:1 (very wide) and 4:5 (portrait).
| Slot | Aspect | Pixel size |
|---|---|---|
| Single image (landscape) | 16:9 | 1600 × 900 |
| Single image (portrait) | 4:5 | 1200 × 1500 |
| Two-image collage | each 1:1 | 1200 × 1200 each |
| Three-image collage | varies | ~1200 × 686 (wide) |
| Header / cover | 3:1 | 1500 × 500 |
| Profile photo | 1:1 | 400 × 400 |
X's image compression is aggressive on JPG (often re-encodes at quality 75). Upload PNG for screenshots with text — even though the file is larger, X's re-encode preserves text better.
LinkedIn favors landscape and square. Portrait works but crops in mobile preview.
| Slot | Aspect | Pixel size |
|---|---|---|
| Single post image | 1.91:1 | 1200 × 627 |
| Square post image | 1:1 | 1200 × 1200 |
| Document / carousel cover | 1:1 | 1080 × 1080 |
| Article header | 1.91:1 | 1280 × 670 |
| Company page cover | 4:1 | 1128 × 191 |
| Profile background | 4:1 | 1584 × 396 |
| Profile photo | 1:1 | 400 × 400 |
LinkedIn keeps the original resolution up to 1200 px wide. Anything larger gets downsampled with surprisingly soft results.
Bonus: Facebook, WhatsApp, TikTok, YouTube
Kept brief because these are less commonly missed:
- Facebook feed: 1200 × 630 (1.91:1) or 1080 × 1080 (square)
- Facebook story: 1080 × 1920 (9:16)
- WhatsApp status: 1080 × 1920 (9:16)
- TikTok video poster / thumbnail: 1080 × 1920
- YouTube thumbnail: 1280 × 720 (must be 16:9)
- YouTube Shorts: 1080 × 1920
The Fast Resize Workflow
When you have a batch of product photos or a graphic to push to 3 platforms, opening Photoshop is overkill. Browser-based resize handles it in seconds:
- Open /resize in any modern browser
- Paste from clipboard (Ctrl+V / ⌘+V) or drag your files in
- Pick the social preset — Instagram Square, Story, X Landscape, LinkedIn Post — or enter custom pixels
- Pick "Cover" (crop to fit) or "Contain" (letterbox if needed)
- Download all as a zip
All computation happens locally. The platform never sees your image before you choose to upload it — handy when you're prepping not-yet-public campaign assets.
Tips That Save Real Time
Design once at 1080 × 1920 (Story/Reel size). Then crop down to feed sizes — going from larger to smaller preserves quality. The reverse (upscaling a 1080×1080 feed image to 1080×1920) requires AI tools or accepting blur.
Keep an "export 4-up" template. For every brand asset, save versions at 1:1, 4:5, 16:9, and 9:16. You'll cover Instagram feed, Instagram portrait, X landscape, and Story/Reel from a single source.
Compress AFTER resizing. Resizing changes dimensions, not file size relative to dimensions. Run /compress on the resized output — typical resized social images are 200-400 KB raw and 50-80 KB after WebP-80.
Test mobile preview first. Most social posts get viewed on phones. The platform's mobile preview will tell you if your text is too small or your subject is in the cropped zone faster than guessing from desktop.
