Social Media Image Sizes Cheat Sheet 2026
Every major social platform has its own pixel dimensions for a profile picture, a cover image and a post, and most of them have changed those dimensions at least once in the last few years without much announcement. The table below lists the sizes the Social Media Image Resizer uses for YouTube, Instagram, Facebook, LinkedIn, X, Pinterest, TikTok and WhatsApp. For each size it names the official help page we opened on 8 November 2026 and says what that page states. Where a page gives the same size the table says Confirmed, where the size sits inside a range or a narrower case the page describes it says Partly confirmed, and where the page gives a different size or none it says Not confirmed. A row with no page named is a size we have not matched to any official source. Bookmark this page rather than the numbers themselves, since a platform can revise a size at any time.
Quick answer: The table below lists the 25 sizes the Social Media Image Resizer uses across eight platforms, such as 1080 x 1080 for an Instagram square post. Each row says whether the platform's own help page confirmed the size, and 13 of the 25 are not. The shape of an image matters more than its exact pixel count.

Why these numbers keep changing
Platforms revise their recommended sizes as they redesign their own interfaces, add new features like Stories or Reels, or change how they crop and compress an uploaded image on their end. A size that was correct a year or two ago can quietly become slightly wrong, which usually shows up as an image being cropped in a way the person who uploaded it did not intend, rather than an outright error. This is also why a screenshot of a size chart from an old blog post is a common source of the wrong number: the chart was accurate when it was written, and nobody went back to update it. That is why the table records which official help page we opened for 22 of the 25 sizes and on what date, so a reader can see what was checked and when before relying on a number.
The sizes that matter most for most people
If only remembering a handful of these, the profile picture sizes and the two most common post shapes cover most day to day posting: a square 1080 x 1080 for Instagram and LinkedIn, a 1200 pixel wide link style image for Facebook and LinkedIn posts, and each platform's cover or banner size for a profile page. Those are all sizes in the table above, and its last columns show which of them a platform's own help page confirmed: for the two square sizes the pages only give a range that contains 1080 x 1080, and the Facebook post size is not confirmed there. The table also lists the same 1080 x 1920 vertical shape for an Instagram Story or Reel and for a TikTok video cover. Neither platform's page gave us that figure, though Instagram's Reels page allows ratios up to 9:16, the shape of 1080 x 1920. A single vertical graphic built at that shape can serve both platforms without a second export, as long as you check each platform's current size before you rely on it.
Safe zones on cover and banner images
A cover or banner image is not shown at its full size on every device: YouTube's channel banner and Facebook's cover photo, in particular, both get cropped differently on desktop versus mobile, so content placed near the edges on one can be cut off on the other. A safe zone marks the area guaranteed to stay visible everywhere, and it matters most for a logo, a name, or any text on the banner. Keeping that content centered within the safe zone rather than spread across the full width avoids a banner that looks fine on desktop and cuts off a name on a phone.
Aspect ratio matters more than the exact pixel count
The precise pixel numbers matter less than the underlying ratio between width and height. A 1080 x 1080 Instagram post and a 2160 x 2160 version of the same image are both perfectly square, and either uploads correctly, since Instagram displays it at whatever size its own interface needs regardless of the exact pixel count you send, as long as the shape is right. Where sizing genuinely goes wrong is uploading the wrong ratio entirely, a landscape photo forced into a square post slot, which forces the platform's own automatic crop to decide what to keep, usually cutting off part of the image nobody intended to lose.
That said, uploading at roughly the size a platform recommends, where it names one, rather than something far larger or far smaller avoids two separate problems: a much larger image than needed just means extra upload time and file size for no visible benefit, since the platform compresses it down anyway, while a much smaller image than needed can come out visibly soft once the platform displays it at a size larger than the source actually supports.
Sizes for a video thumbnail versus a video cover
YouTube's thumbnail and TikTok's video cover serve the same basic purpose, a still image representing a video before someone presses play, but at very different shapes. The table lists 1280 x 720 for the YouTube thumbnail, a wide 16:9 frame, and YouTube's own page asks for the same 16:9 shape at a larger size, 3840 x 2160. It lists 1080 x 1920 for the TikTok video cover, the same tall 9:16 shape as a vertical video, and TikTok's page gives no cover size. Preparing a cover image for one platform and reusing it directly on the other, without reframing, is one of the more common social media sizing mistakes, since the two shapes are effectively rotated versions of each other rather than close enough to swap freely.
How much of a phone photo each crop keeps
A typical 12 megapixel phone photo is 4000 x 3000 pixels, a 4:3 landscape frame. Crop to fill scales it until the preset is fully covered and trims whatever overflows, so the share of the original that survives depends on how far the preset's shape is from 4:3:
| Preset | Size (pixels) | Part of the photo kept (percent) | Measured along |
|---|---|---|---|
| Instagram square post | 1080 x 1080 | 75 | Width |
| Instagram portrait post | 1080 x 1350 | 60 | Width |
| Instagram Story or Reel | 1080 x 1920 | 42 | Width |
| Pinterest pin | 1000 x 1500 | 50 | Width |
| YouTube thumbnail | 1280 x 720 | 75 | Height |
| LinkedIn personal banner | 1584 x 396 | 33 | Height |
The crop is centered unless the Position setting moves it toward the top, bottom, left or right, which helps when the subject sits off center. In the tall formats a horizontal photo loses more than half its width, so a group shot or a wide view rarely works as a Story; a photo taken in portrait orientation is the simpler fix.
The safe zones in numbers
Two presets draw a dashed safe zone on the preview. On the YouTube channel banner it marks the central 1546 x 423 pixels of the 2560 x 1440 canvas, less than 18 percent of the whole image, and that narrow middle band is the only part sure to show on every screen. On the tool's Facebook desktop cover preset it marks the middle 640 x 312 pixels of 820 x 312, which means the outer 90 pixels on each side can be cut off when the cover is viewed on a phone.
One tool, every platform
Rather than looking up each platform's current size separately, the Social Media Image Resizer keeps this whole list in one place, grouped by platform, so switching between a YouTube thumbnail and an Instagram Story is a matter of picking a different preset rather than opening a different tab to find the number. The dedicated YouTube, Instagram, Facebook, LinkedIn and X pages cover the same presets individually for anyone who only ever needs one platform's sizes and prefers a shorter list.
