The 2026 social media image size guide: exact recommended dimensions for Instagram, Facebook, X, LinkedIn, YouTube and TikTok, plus free resizing tips.
You spent an hour on the perfect photo. You upload it, and the platform crops your subject's head off, compresses it into a blurry smear, or letterboxes it with ugly bars. The image was fine — the size was wrong.
Size images for any platform: the free image resizer hits exact dimensions fast.
Every social platform has its own preferred dimensions, and they enforce them ruthlessly. Upload at the wrong size and you get automatic cropping, aggressive recompression, or both. This guide gives you the recommended dimensions for every major platform in 2026, explains why sizing matters more than most people think, and shows you how to resize anything in seconds for free.
Instagram is the fussiest platform about dimensions, and also the one where visuals matter most.
- Feed post (portrait): 1080 × 1350 px (4:5). This is the sweet spot — it takes up the most screen space in the feed.
- Feed post (square): 1080 × 1080 px (1:1). The classic; safe but smaller on screen.
- Feed post (landscape): 1080 × 566 px (1.91:1). Use only when the composition demands it.
- Stories and Reels: 1080 × 1920 px (9:16). Full vertical.
- Reel cover: 1080 × 1920 px, but keep key elements inside the central 1080 × 1350 zone — the feed preview crops the top and bottom.
- Profile picture: 320 × 320 px, displayed as a circle. Keep faces and logos away from the edges.
Note the pattern: 1080 px on the short edge is Instagram's standard. Uploading larger is fine — Instagram downscales — but uploading smaller means Instagram upscales, and upscaling is where blur comes from.
Facebook recompresses everything aggressively, so starting from a clean, correctly-sized file matters even more here.
- Feed post: 1200 × 630 px (1.91:1) for links, or 1080 × 1350 px (4:5) for photos.
- Stories: 1080 × 1920 px (9:16), same as Instagram.
- Cover photo: 820 × 312 px on desktop, 640 × 360 px on mobile — design for the mobile crop, because that is where most views happen.
- Profile picture: 720 × 720 px minimum, shown as a circle.
- Event cover: 1920 × 1005 px.
Facebook's compression is the harshest of any major platform. Export photos at high quality before uploading — the platform will do its own crushing, so give it the best possible starting point.
X (Twitter)
X keeps images closer to their original quality than Meta's platforms, but the timeline crop still catches people out.
- In-feed image: 1600 × 900 px (16:9). This is the size that displays uncropped in the timeline.
- Header: 1500 × 500 px.
- Profile picture: 400 × 400 px, displayed as a circle.
- Card/link image: 1200 × 628 px.
The timeline shows a 16:9 crop of taller images, so if your image is portrait, the preview will slice off the top and bottom until someone clicks through. Design accordingly.
LinkedIn is where blurry images do the most professional damage. A pixelated banner on a company page reads as carelessness.
- Personal profile banner: 1584 × 396 px. A very wide, short strip — most designs fail here because people treat it like a normal banner.
- Company page logo: 300 × 300 px.
- Company page banner: 1128 × 191 px.
- Post image: 1200 × 627 px (1.91:1), the same ratio as a link preview.
- Article cover: 1200 × 644 px.
Because the banner is so extremely wide, the common mistake is uploading a normal photo and letting LinkedIn crop a thin slice from the middle. Build the banner at the real dimensions instead.
YouTube
YouTube images are fewer but higher-stakes — the thumbnail decides whether anyone clicks at all.
- Video thumbnail: 1280 × 720 px (16:9). Minimum width 640 px. Keep text large — most views happen on phones where the thumbnail is tiny.
- Channel banner: 2560 × 1440 px, but only the central 1546 × 423 px "safe area" shows on all devices. Put your channel name and tagline in that strip; treat the rest as decorative bleed.
- Profile picture: 800 × 800 px, displayed as a circle.
- Shorts thumbnail: 1080 × 1920 px (9:16).
The banner safe area is the single most-ignored spec on this list. Design the full 2560 × 1440 canvas, but assume everything outside the middle strip is invisible on phones and tablets.
TikTok
TikTok is almost entirely vertical video, but still images show up in profile elements and photo carousels.
- Video/photo posts: 1080 × 1920 px (9:16).
- Profile picture: 200 × 200 px minimum, displayed as a circle.
- Photo carousels: 1080 × 1920 px per slide for full-screen display.
TikTok overlays its UI — username, caption, like buttons — on the right side and bottom of the screen. Keep important content away from those zones or it will be covered.
Why Getting Sizes Right Actually Matters
Automatic cropping. Every platform crops to its preferred shape without asking. Upload a landscape photo as a story and the platform picks what to keep — usually the middle, regardless of where your subject is.
Recompression. Platforms shrink and re-encode every upload. If your file is already at the platform's native resolution, the damage is minimal. If it is much larger, the downscale can introduce softness; if smaller, the upscale introduces blur. Either way, you lose.
Algorithmic signals. This is the part people underestimate. Platforms measure how long people look at and engage with your content. A crisp, well-framed image gets more attention than a blurry, awkwardly cropped one — and the algorithm notices the difference in engagement even though it never "sees" the image quality directly.
Brand perception. On LinkedIn and company pages especially, a stretched logo or pixelated banner quietly tells viewers you do not sweat the details. Correct sizing is one of the cheapest credibility upgrades available.
How to Resize Images Free in Seconds
Knowing the dimensions is half the battle; the other half is resizing without installing Photoshop. The workflow is simple:
- Pick your target dimensions from the lists above. When a platform accepts a range, use the recommended size, not the minimum.
- Open the free image resizer and upload your photo. If it runs entirely in your browser — test by going offline after the page loads — then nothing is uploaded to a server.
- Set the exact pixel dimensions and choose how to handle the shape difference: crop to fill (best for social), or fit with padding (best when you cannot lose any content).
- Download and check the result at actual size before uploading.
Two related jobs come up constantly alongside resizing. First, file size: a correctly-sized image can still be megabytes, and platforms punish slow-loading media. Run it through the free image compressor to shrink the file without visible quality loss. Second, format choice: modern formats like WebP and AVIF look better at smaller sizes than old JPEG. If you are unsure which format to use where, the image format guide breaks down JPG vs PNG vs WebP vs AVIF, and the compression guide goes deeper on shrinking files without the mush.
A practical habit: keep one high-resolution master of every important image, and generate each platform's size from the master. Never resize a resized copy — every generation loses detail.
Frequently Asked Questions
What happens if I upload the wrong size? The platform fixes it for you, badly. It will crop to its preferred aspect ratio (usually center-crop), then scale and recompress. Faces get cut, text gets sliced, and fine detail turns to mush. Resizing beforehand puts you in control of the crop.
Should I upload the largest size possible? Not necessarily. Uploading far above the recommended size just means the platform's downscaler does more work, and its downscaler is not gentle. Aim for the recommended dimensions or modestly above — roughly 1-2× the display size at most.
Why do my images look blurry after uploading? Three usual causes: the source was smaller than the display size (upscaling blur), the platform's compression was harsh (common on Facebook), or the file was saved at low quality before upload. Start from a high-quality file at the recommended dimensions.
Do these sizes change often? The core aspect ratios are stable — 9:16 vertical, 1:1 square, 16:9 landscape have been standard for years. Pixel recommendations drift upward slowly as screens get denser. Check this guide yearly; the ratios will almost certainly still be right.
Can I use one image size for all platforms? You can, but you should not. A square image works acceptably on Instagram and Facebook feeds, yet it will be cropped on X's timeline, letterboxed in stories, and look lost as a YouTube thumbnail. Two minutes of resizing per platform beats one compromised image everywhere.
Conclusion
Correct image sizes are unglamorous and disproportionately effective. No single change improves how your content looks across platforms more than uploading at each platform's recommended dimensions: 1080 × 1920 for vertical, 1080 × 1080 or 1080 × 1350 for Instagram feed, 1280 × 720 for YouTube thumbnails, and the rest from the lists above. Pair that with compression and the right format, and your visuals will look deliberate everywhere instead of accidentally cropped somewhere.

Why Sizes Matter More Than You Think
Every platform crops, compresses, and displays on its own terms. Upload the wrong size and the platform decides for you — usually by cropping the interesting part. The right size is not vanity; it is control. Control over what viewers see, how sharp it looks, and whether your carefully designed graphic survives the platform’s processing. Ten minutes with a size guide beats ten posts with cropped headlines.
The Universal Principles (Before Platform Specifics)
- Upload at recommended size or modestly above: roughly 1-2x the display size at most — more is wasted bytes.
- Keep text large and high-contrast: platform compression eats fine detail first.
- Design safe zones: keep critical content away from edges where cropping and overlays strike.
- Test on a real phone: most viewing is mobile; the desktop preview lies.
- Compress after resizing: right size plus compression is the complete formula.
Profile Images and Logos
Avatars display tiny and circular on most platforms — design for the small circle, not the large square. Simple, high-contrast marks survive; detailed logos do not. Keep a dedicated avatar version of your logo: simplified, centered, with breathing room. The full logo belongs on the website; the avatar is a different job.
Feed Posts and Banners
Banners and covers get cropped differently on desktop versus mobile — design with the overlap zone in mind, keeping text and faces in the area visible on both. Feed images should be sized to the platform’s preferred dimensions so they display fully instead of being awkwardly cropped in the grid. When a platform changes its layout (and they all do, regularly), re-check your key visuals.
Stories and Vertical Formats
Vertical is the native language of stories: full-screen 9:16, with the top and bottom margins reserved — platform UI overlays live there. Keep captions and calls-to-action in the middle band. Design vertically from the start; cropping a horizontal image into vertical is how heads get cut off. The vertical format rewards bold, simple compositions.
Video Thumbnails and Covers
Thumbnails are tiny billboards: readable at a glance, high contrast, minimal text (a few words at most), expressive imagery. They are judged in milliseconds against dozens of competitors. Size them to the platform’s spec, compress well, and A/B test when the platform allows — thumbnail changes are among the highest-leverage edits in content publishing.
When Platforms Change the Rules
They will — dimensions shift, layouts redesign, new formats appear. The durable strategy: keep master files at high resolution, export per-platform sizes from the masters, and re-export when specs change. Never upscale an old export to meet a new larger spec; go back to the master. A small "social sizes" folder per campaign, generated fresh each time, beats a graveyard of outdated exports. Treat every dimension in this guide as current as of 2026 and verify against each platform's official guidelines before final exports - specs change, and the platform's own documentation is the final word.
Common Mistakes
- One size for every platform: the most common failure — each platform gets its own export.
- Text too small: if you must squint at full size, mobile viewers have no chance.
- Ignoring safe zones: headlines hidden under profile overlays and UI chrome.
- Uploading uncompressed giants: slow uploads, platform recompression, wasted time.
- Forgetting to update after redesigns: stale banners signal a stale account.
The Efficient Workflow
Resize with the image resizer, compress with the image compressor, and keep a per-campaign folder of platform exports from high-resolution masters. Batch the exports: do all platforms for one visual in one sitting, while the design decisions are fresh. The whole pipeline takes minutes per visual — and every post looks intentional instead of accidental.
Frequently Asked Questions
Do I really need different sizes per platform? Yes — cropping and display differences are real, and the wrong size visibly degrades your content.
What if a platform changes its dimensions? Re-export from your high-resolution masters. This is why masters exist.
PNG or JPG for social images? Photos: JPG (or WebP where accepted). Graphics with text: PNG. Compress either way.
How often should I update banners? When they look dated, when the platform redesigns, or per campaign — whichever comes first.
"The right size is control: over what viewers see, how sharp it looks, and whether your design survives the platform."
Your Next Post
Before your next upload, check the platform’s current recommended size, export exactly that from your master, compress, and compare with your last post. The difference is usually visible immediately — sharper, better framed, more professional. Then build the habit: every visual, every platform, right size, every time. Your feed will thank you.
