Every social media platform has different image size requirements, and they change frequently. Using the wrong dimensions means your images get cropped awkwardly, display blurry, or lose important content at the edges.
This cheat sheet lists every major image dimension for every major platform in 2026. Bookmark it, and use BestPNG's social resize tool to instantly resize your images to any platform's specifications.
Instagram Image Sizes
Instagram is the most dimension-sensitive platform. Feed posts, stories, reels, and profile pictures all have different requirements.
| Image Type | Dimensions (px) | Aspect Ratio | Max File Size |
|---|---|---|---|
| Square Post | 1080 x 1080 | 1:1 | 30 MB |
| Portrait Post | 1080 x 1350 | 4:5 | 30 MB |
| Landscape Post | 1080 x 566 | 1.91:1 | 30 MB |
| Story / Reel | 1080 x 1920 | 9:16 | 30 MB |
| Profile Picture | 320 x 320 | 1:1 | — |
| Carousel | 1080 x 1080 or 1080 x 1350 | 1:1 or 4:5 | 30 MB per image |
Tips:
- Portrait (4:5) posts take up the most screen real estate in the feed and generally perform best
- All carousel images must use the same aspect ratio — the first image sets it for the entire set
- Profile pictures display at 150x150 on mobile but upload at 320x320 minimum
- Keep text and important elements away from the top and bottom 250px of stories (UI overlay zones)
Facebook Image Sizes
Facebook uses multiple image formats across feed posts, cover photos, events, and ads.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Feed Post (Link Share) | 1200 x 630 | 1.91:1 |
| Feed Post (Photo) | 1200 x 1200 or 1200 x 630 | 1:1 or 1.91:1 |
| Cover Photo | 820 x 312 | 2.63:1 |
| Profile Picture | 170 x 170 | 1:1 |
| Event Cover | 1200 x 628 | 1.91:1 |
| Group Cover | 1640 x 856 | 1.91:1 |
| Story | 1080 x 1920 | 9:16 |
Tips:
- Cover photos display differently on mobile (640x360 crop) vs desktop (820x312) — keep text centered
- Square images (1:1) get more engagement than landscape in the feed
- Facebook compresses images aggressively; upload PNG for graphics with text and JPG for photos
Twitter/X Image Sizes
Twitter/X crops images in the feed timeline and expands them when clicked.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Single Image Tweet | 1600 x 900 | 16:9 |
| Two Images | 700 x 800 each | 7:8 |
| Three Images | 700 x 800 (left) + 700 x 400 (right x2) | Mixed |
| Four Images | 700 x 400 each | 7:4 |
| Header / Banner | 1500 x 500 | 3:1 |
| Profile Picture | 400 x 400 | 1:1 |
| Card Image (link preview) | 800 x 418 | 1.91:1 |
Tips:
- Single image tweets: 16:9 fills the timeline perfectly without cropping
- Timeline preview crops to roughly 2:1 on mobile — center your content vertically
- Profile pictures are displayed as circles; keep content within the circular safe zone
LinkedIn Image Sizes
LinkedIn has specific sizes for personal profiles, company pages, and article covers.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Feed Post | 1200 x 627 or 1080 x 1080 | 1.91:1 or 1:1 |
| Article Cover | 1200 x 644 | 1.86:1 |
| Profile Photo | 400 x 400 | 1:1 |
| Background Photo | 1584 x 396 | 4:1 |
| Company Logo | 300 x 300 | 1:1 |
| Company Cover | 1128 x 191 | 5.9:1 |
Tips:
- Square (1:1) images and documents/carousels perform best in the LinkedIn feed
- Company cover images are extremely wide — use simple designs with centered text
- LinkedIn supports PDF carousel posts (upload as documents) which outperform regular posts
TikTok Image Sizes
TikTok is primarily video, but image-based content (photo carousel posts) and profile elements matter.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Video / Photo Post | 1080 x 1920 | 9:16 |
| Profile Picture | 200 x 200 | 1:1 |
| Photo Carousel | 1080 x 1920 | 9:16 |
Tips:
- All visual content is vertical (9:16) — never post horizontal content on TikTok
- Keep important content in the center 60% of the screen; the top and bottom are covered by UI elements
- Photo carousel posts (TikTok Photo Mode) use the same 9:16 dimensions as video
Pinterest Image Sizes
Pinterest favors tall, vertical images. Taller pins get more visibility in the feed.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Standard Pin | 1000 x 1500 | 2:3 |
| Long Pin | 1000 x 2100 | 1:2.1 |
| Square Pin | 1000 x 1000 | 1:1 |
| Profile Picture | 165 x 165 | 1:1 |
| Board Cover | 222 x 150 | 3:2 |
Tips:
- 2:3 ratio (1000x1500) is the sweet spot — tall enough to dominate the feed, short enough to display fully
- Pins taller than 2:3 get truncated in the feed and require a tap to see fully
- Use bold, readable text at the top of pins — most users scan quickly without opening
YouTube Image Sizes
YouTube has specific requirements for thumbnails, channel art, and community posts.
| Image Type | Dimensions (px) | Aspect Ratio |
|---|---|---|
| Video Thumbnail | 1280 x 720 | 16:9 |
| Channel Banner | 2560 x 1440 | 16:9 (safe area: 1546 x 423) |
| Profile Picture | 800 x 800 | 1:1 |
| Community Post Image | 1200 x 675 | 16:9 |
Tips:
- Thumbnails are displayed as small as 168x94 pixels — use large, bold text (3-4 words max)
- Channel banners have a "safe area" of 1546x423 centered within the full 2560x1440; text and logos must stay in the safe zone
- Custom thumbnails require a verified account; they're the single most important factor for click-through rate

How to Resize for Any Platform with BestPNG
Instead of memorizing these dimensions, use BestPNG's social resize tool which has all platform presets built in:
- Go to bestpng.com/tools/social-resize
- Upload your image
- Select the target platform and image type from the preset menu
- The tool automatically sets the correct dimensions and shows a crop preview
- Adjust the crop area to frame your content correctly
- Download the resized image
The tool handles both downscaling (large images to platform size) and aspect ratio conversion (cropping landscape to portrait or vice versa).
Frequently Asked Questions
What image format should I use for social media?
JPG for photographs (smaller file size, good quality). PNG for graphics with text, logos, or transparency (sharper text rendering, no compression artifacts). Most platforms accept both.
Do social platforms compress my images?
Yes, every major platform re-compresses uploaded images. To minimize quality loss, upload at the recommended dimensions (not larger) and use high-quality source files. Facebook and Instagram compress more aggressively than Twitter/X or LinkedIn.
What if my image doesn't match the recommended aspect ratio?
The platform will crop it automatically, usually centering the crop. This often cuts off important content at the edges. Using BestPNG's social resize tool lets you control exactly what gets cropped before uploading.
Can I use the same image across all platforms?
You can, but it won't look optimal anywhere. A 1080x1350 Instagram portrait gets awkwardly cropped on Twitter (which expects 16:9) and wastes vertical space on Pinterest (which prefers 2:3). For best results, resize specifically for each platform.
How often do social media image sizes change?
Platforms update their dimensions once or twice a year, usually with redesigns or new features. This guide is current as of early 2026. Check back periodically for updates, or use BestPNG's social resize presets which are kept up to date.
Conclusion
Getting social media image sizes right is one of the easiest ways to make your content look professional. The wrong dimensions lead to awkward crops, blurry images, and lost engagement.
