Wrong Dimensions: Why Your Images Look Bad After Upload
Every social media platform has a native display size for each content type. When you upload an image that does not match these dimensions, one of three things happens: the platform crops the image (often cutting off the important part), the platform stretches or squishes it (distorting the aspect ratio), or the platform resamples it (causing blurriness).
The platforms' image processing pipelines are optimized for their native sizes. Images uploaded at exactly the right dimensions pass through with minimal additional processing. Images at wrong sizes trigger resampling algorithms that introduce blurriness and quality loss.
Platforms also boost native-format content. Instagram's algorithm measurably favors Reels at 9:16 and feed posts at 4:5 (portrait). Facebook prioritizes images with the correct aspect ratio for link previews. Getting dimensions right is partly an SEO/algorithm issue, not just an aesthetics issue. See our guide on why images look blurry after uploading for a deeper explanation of what platforms do to your images.
Here are the current recommended dimensions for every major platform in 2026. Where platforms accept a range, we have listed the optimal size for maximum quality and algorithm compatibility.
Instagram Image Sizes 2026
Instagram supports three feed aspect ratios: square, portrait, and landscape. Portrait (4:5) consistently outperforms square and landscape in reach because it takes up more vertical screen space in the feed, keeping users on your content longer.
| Content Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Feed (square) | 1080 x 1080 px | 1:1 | Classic format; works well for branded content |
| Feed (portrait) | 1080 x 1350 px | 4:5 | Best reach; takes up most feed space |
| Feed (landscape) | 1080 x 566 px | 1.91:1 | Good for wide scenes and panoramas |
| Stories & Reels | 1080 x 1920 px | 9:16 | Full-screen vertical; leave safe zones at top and bottom |
| Profile picture | 320 x 320 px | 1:1 | Displayed as small circles; use simple, centered imagery |
| Explore grid thumbnail | 1080 x 1080 px | 1:1 | Square crop used in Explore; design for center |
Safe zone for Stories and Reels: Instagram overlays UI elements (username, reactions, caption) at the top and bottom of Stories. Keep your main subject and any text within the central 1080x1420 px area (leaving 250px of padding at top and bottom).
Twitter / X Image Sizes 2026
Twitter/X displays images in the feed at a fixed aspect ratio regardless of what you upload. Portrait images are cropped to a landscape crop in the feed preview, with users needing to click to see the full image. Upload images at the native display ratio to avoid unexpected crops.
| Content Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| In-feed image (single) | 1600 x 900 px | 16:9 | Best quality; displays at full width in feed |
| In-feed image (1:1) | 1080 x 1080 px | 1:1 | Square crops reliably in feed preview |
| Profile picture | 400 x 400 px | 1:1 | Displayed as circle; minimum 200x200 |
| Header / banner | 1500 x 500 px | 3:1 | Keep important content in center; edges crop on mobile |
| Twitter Card image | 1200 x 628 px | 1.91:1 | Used when sharing links; set via og:image meta tag |
Twitter/X compresses PNG to JPEG automatically when the PNG is above a certain file size. To control quality: upload JPEG files with quality 85-90%, or upload PNG for graphics with text where JPEG artifacts would be visible on sharp edges.
Facebook Image Sizes 2026
Facebook has multiple content surfaces with different optimal sizes. The most important dimension to get right is the link preview image — this is the image shown when you share a URL and it directly affects click-through rates on shared links.
| Content Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Feed photo post | 1200 x 630 px | 1.91:1 | Reliable display across feed and sharing |
| Feed square post | 1080 x 1080 px | 1:1 | Good for product shots and branded images |
| Story | 1080 x 1920 px | 9:16 | Full-screen vertical; same as Instagram Stories |
| Profile picture | 170 x 170 px | 1:1 | Displayed as circle; keep subject centered |
| Cover photo | 820 x 312 px | 2.63:1 | Crops to 640x360 on mobile — design for both |
| Event cover | 1200 x 628 px | 1.91:1 | Same as feed posts |
| Link preview (og:image) | 1200 x 628 px | 1.91:1 | Critical for link clicks; set via open graph meta |
The og:image tag matters beyond Facebook. The 1200x628 image you set via og:image is also used by WhatsApp, Slack, Telegram, LinkedIn, and Twitter when your URL is shared. Setting this single image correctly improves previews across the entire social web.
LinkedIn Image Sizes 2026
LinkedIn has a more professional audience and a feed that emphasizes document and article content. Images here need to look sharp and professional — blurriness from wrong dimensions will undermine credibility more than on casual platforms.
| Content Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Feed post image | 1200 x 627 px | 1.91:1 | Standard feed image; 4:5 portrait also works well |
| Feed portrait image | 1080 x 1350 px | 4:5 | Takes more feed space; increases engagement |
| Article cover image | 1920 x 1080 px | 16:9 | Used as hero in long-form LinkedIn articles |
| Profile photo | 400 x 400 px | 1:1 | Professional headshot; displayed as circle |
| Company logo | 300 x 300 px | 1:1 | Appears next to company name in feed and search |
| Company cover | 1128 x 191 px | 5.9:1 | Wide banner; keep branding to left side |
YouTube Image Sizes 2026
YouTube's most important image is the video thumbnail — the image that determines whether someone clicks on your video in search results, recommendations, and the home feed. A well-designed thumbnail at the correct dimensions is one of the highest-leverage things you can do for YouTube growth.
| Content Type | Recommended Size | Aspect Ratio | Notes |
|---|---|---|---|
| Video thumbnail | 1280 x 720 px | 16:9 | Minimum 640x360; 1280x720 is the sweet spot |
| Channel banner | 2560 x 1440 px | 16:9 | Displays at different crops on TV, desktop, and mobile |
| Channel icon | 800 x 800 px | 1:1 | Displayed as circle; minimum 98x98 |
| Shorts | 1080 x 1920 px | 9:16 | Vertical format; same as TikTok and Reels |
| Video watermark | 150 x 150 px | 1:1 | Small corner overlay; keep design simple |
YouTube thumbnail file size limit is 2MB. A 1280x720 JPEG at 85% quality is typically 80-150KB, well within this limit. Use the JPEG compressor if your exported thumbnail exceeds the limit.
TikTok and Pinterest Image Sizes 2026
| Platform | Content Type | Recommended Size | Notes |
|---|---|---|---|
| TikTok | Videos and photos | 1080 x 1920 px | 9:16 vertical; same as all short-form video |
| TikTok | Profile picture | 200 x 200 px | Keep it simple and recognizable at small sizes |
| Standard pin | 1000 x 1500 px | 2:3 ratio performs best in the feed | |
| Square pin | 1000 x 1000 px | 1:1; less feed space but works for some content | |
| Profile photo | 165 x 165 px | Upload at 400x400 minimum for quality |
Pinterest is still a major traffic source for blogs and e-commerce. A well-designed 1000x1500 pin with clear text overlay and your URL visible in the image consistently outperforms shorter pins. The 2:3 ratio fills the most screen space in Pinterest's masonry feed.
Resize Images for Any Platform — Free, in Seconds
You do not need design software to resize images for social media. These free tools handle all the platform sizes described above:
Use the Social Media Resizer for preset platform sizes
The Social Media Resizer includes preset dimensions for every major platform — Instagram square, portrait, Stories, Twitter, Facebook, LinkedIn, YouTube thumbnail, and more. Select your platform, upload your image, and download the correctly sized version in seconds.
Use the Image Resizer for custom dimensions
When you need a specific pixel dimension not covered by presets — like a LinkedIn article cover at 1920x1080 or a Pinterest pin at 1000x1500 — the Image Resizer lets you set exact pixel dimensions with optional aspect ratio lock.
Use the Image Cropper to fit a specific aspect ratio
When your image is the right size overall but the wrong aspect ratio, the Image Cropper lets you select and export exactly the region you want — without distorting the image by stretching.
Compress after resizing
After resizing to the correct dimensions, compress the output to keep file sizes small. Instagram has a 30MB limit for photos but compresses anything above about 1MB — compressing to 200-500KB before upload gives you control over the compression output.

<a href="/edit/social-media-resizer/" style="color:#d4960f;font-weight:600;">Preset sizes for all platforms</a> — Instagram, Twitter, Facebook, LinkedIn, YouTube, TikTok.
Image Resizer
<a href="/edit/image-resizer/" style="color:#d4960f;font-weight:600;">Custom pixel dimensions</a> — set exact width and height with aspect ratio lock.
Image Cropper
<a href="/edit/image-cropper/" style="color:#d4960f;font-weight:600;">Crop to any ratio</a> — select the exact region you want without distortion.
Compress for Upload
<a href="/compress/compress-jpg/" style="color:#d4960f;font-weight:600;">Compress JPEG</a> or <a href="/compress/compress-png/" style="color:#d4960f;font-weight:600;">PNG</a> after resizing to control quality before the platform recompresses.
If your images are still looking blurry after resizing to the correct dimensions, the issue is likely platform re-compression of already-compressed images. See our guide on why images look blurry after uploading for the full explanation and fixes.
