Complete Social Media Image Size Guide 2026 (Instagram, Facebook, LinkedIn, X, YouTube, Pinterest, TikTok)
If you have ever uploaded a perfectly good photo to a cover banner slot and watched the platform crop your subject's head clean off, you already know why this guide exists. Every social network compresses, crops, and re-encodes your images the moment they land on their servers — and each one does it according to its own, rarely-documented rulebook.
This handbook consolidates the exact 2026 pixel dimensions, aspect ratios, and file-size ceilings for every major platform, along with the "safe zone" logic that decides what actually stays visible after a platform's auto-crop runs. Bookmark it, because platforms tend to quietly revise these numbers roughly once a year.
1. Why Platforms Resize Your Images Automatically
Every social network normalizes uploaded media into a small number of standard containers before it renders your image in feeds, grids, stories, and search cards. Three things determine how your photo will look after upload:
- Server-side re-compression: Platforms almost universally re-encode images to JPEG or WebP at a lower bitrate to save bandwidth, which is why sharp originals sometimes look slightly soft after upload.
- Aspect-ratio cropping: If your source image doesn't match the platform's expected ratio, an algorithm — not you — decides which part of the frame to keep.
- Safe zones: Circular profile pictures, avatar overlaps on banners, and mobile-vs-desktop reflow areas all clip differently, so text or faces placed near the edges are the first casualties.
Uploading at the *exact* target dimension sidesteps all three problems, because there is nothing left for the platform's algorithm to guess.
2. Instagram Image Sizes
Instagram remains one of the strictest platforms for aspect ratio enforcement, especially in the feed.
| Placement | Recommended Pixels | Aspect Ratio | Notes |
|---|---|---|---|
| Square Post | 1080 × 1080 px | 1:1 | Safest default for feed grids |
| Portrait Post | 1080 × 1350 px | 4:5 | Occupies the most vertical feed space |
| Landscape Post | 1080 × 566 px | 1.91:1 | Rarely ideal — gets cropped on mobile |
| Story / Reel | 1080 × 1920 px | 9:16 | Keep key text inside the middle 60% |
| Profile Picture | 320 × 320 px | 1:1 (circular) | Displayed in a circular mask |
| Reel Cover | 1080 × 1920 px | 9:16 | Text must sit above the bottom UI bar |
Common mistake: uploading a horizontal landscape photo straight to the feed. Instagram will crop it to 1.91:1 without warning, which often slices off the edges of group photos.
3. Facebook Image Sizes
Facebook runs on a mix of legacy and modern placements, and the numbers below are the current 2026 specs across Pages, personal profiles, and Events.
| Placement | Recommended Pixels | Notes |
|---|---|---|
| Cover Photo | 851 × 315 px | Displays differently on desktop vs mobile — keep subjects centered |
| Profile Picture | 360 × 360 px | Cropped into a circle on most surfaces |
| Shared Post Image | 1200 × 630 px | Also the standard Open Graph share-card size |
| Event Cover | 1200 × 628 px | Nearly identical to post images but a distinct upload slot |
Facebook's cover photo is the single most-abused dimension on the platform. Because desktop and mobile render different crops of the same 851×315 canvas, always keep faces and logos within the centre 70% of the frame.
4. LinkedIn Image Sizes
LinkedIn's professional audience makes crisp, correctly-sized banners disproportionately important for personal branding and company pages.
| Placement | Recommended Pixels | Notes |
|---|---|---|
| Profile Picture | 400 × 400 px | Square headshot, cropped circular in the feed |
| Personal Banner | 1584 × 396 px | Avoid placing text behind the avatar overlap zone (bottom-left) |
| Company Page Cover | 1128 × 191 px | Much shorter aspect ratio than the personal banner |
| Feed Post Image | 1200 × 1200 px | Square performs most consistently across mobile and desktop |
5. X (Twitter) Image Sizes
| Placement | Recommended Pixels | Notes |
|---|---|---|
| Profile Picture | 400 × 400 px | Circular crop applied automatically |
| Header / Banner | 1500 × 500 px | 3:1 ratio; avoid text near the avatar corner |
| Timeline Post Image | 1200 × 675 px | 16:9 ratio, the platform's preferred landscape crop |
6. YouTube Image Sizes
| Placement | Recommended Pixels | File Size Limit | Notes |
|---|---|---|---|
| Video Thumbnail | 1280 × 720 px | Under 2 MB | 16:9 ratio, JPG/PNG/GIF/WebP accepted |
| Channel Banner | 2560 × 1440 px | — | Only the centre 1546 × 423 px "TV-safe" zone is guaranteed visible on every device |
| Channel Profile Picture | 800 × 800 px | — | Displayed circular; final render is often only 98 × 98 px |
The channel banner is notoriously unforgiving: the full canvas is 2560×1440, but text or logos outside the middle safe zone will be cropped off on TVs and some desktop browsers.
7. Pinterest Image Sizes
| Placement | Recommended Pixels | Aspect Ratio | Notes |
|---|---|---|---|
| Standard Pin | 1000 × 1500 px | 2:3 | Taller pins get more visibility in the feed |
| Board Cover | 1000 × 1000 px | 1:1 | Square crop for the board thumbnail |
| Profile Picture | 165 × 165 px | 1:1 (circular) | Small — keep logos simple |
8. TikTok and WhatsApp Image Sizes
| Platform | Placement | Recommended Pixels | Notes |
|---|---|---|---|
| TikTok | Profile Picture | 200 × 200 px | Circular crop |
| TikTok | Channel Cover | 900 × 300 px | 3:1 widescreen banner |
| Display Picture (DP) | 640 × 640 px | Circular crop on most devices | |
| Status | 1080 × 1920 px | Full-screen 9:16 vertical |

10. Five Mistakes That Ruin Social Media Images
Even with the correct pixel dimensions in hand, a few recurring habits still undermine image quality across every platform:
- Uploading a screenshot instead of the original file. Screenshots re-compress an already-compressed image, stacking two rounds of quality loss on top of each other. Always start from the original photo or export, never a screenshot of it.
- Resizing up from a small source. Stretching a 400×400 px image up to fill a 1920×1080 px banner slot doesn't add detail — it just blurs existing pixels across a larger canvas. If your source is smaller than the target dimension, look for a higher-resolution original instead of upscaling.
- Ignoring the safe zone on circular crops. Profile pictures across every platform are displayed inside a circular mask, even though you upload a square file. Important details placed in the corners of a square upload — like the edge of a logo — get silently clipped by the circle.
- Forgetting mobile vs. desktop crop differences. Facebook and LinkedIn banners render different visible regions on mobile versus desktop from the same source file. Centering your key content, rather than placing it near any edge, avoids losing it on one device type or the other.
- Saving in the wrong file format for the content type. Photographs compress well as JPG; screenshots, graphics with text, and logos with flat colors hold up far better as PNG, since JPG's compression tends to introduce visible artifacts around sharp text edges.
11. Frequently Asked Questions
Why does my Instagram photo look zoomed in after uploading?
This almost always happens when the source image's aspect ratio doesn't match Instagram's expected ratio for that placement (1:1, 4:5, or 9:16). Instagram crops to fit rather than adding letterboxing, so any mismatch results in an automatic — and sometimes unflattering — crop.
Should I upload at higher resolution than the platform requires "just in case"?
Generally no. Platforms re-compress everything server-side regardless of what you upload, so oversized files mostly just slow down your upload without improving final quality. Matching the recommended dimension closely, at good source quality, is the more reliable approach.
Do these dimensions change often?
Platforms revise banner and cover dimensions periodically, usually alongside major redesigns — LinkedIn and Facebook have both changed banner specs more than once in recent years. It's worth rechecking dimensions for high-visibility assets like company banners every year or so.
12. How to Batch-Resize for Every Platform in One Session
Manually cropping the same source photo a dozen different ways is tedious and error-prone. ResizeHub's platform-specific resizers apply the exact pixel canvas and safe-zone guides automatically, entirely inside your browser:
- Pick the platform preset: Open the dedicated resizer for the placement you need — for example
/tools/instagram-photo-resizeror/tools/linkedin-banner. - Drop in your source image: Use your highest-resolution original, not a screenshot or an already-compressed copy.
- Align using the safe-zone overlay: Many of our social presets show avatar-overlap and TV-safe guides directly on the canvas.
- Export and upload: Download the correctly-sized file and upload it directly — no further platform-side cropping surprises.
