The Complete Social Media Image Size Guide
ResizerPhoto.in Blog
Every major social platform has its own preferred image dimensions, and those dimensions change often enough that keeping track of them from memory is nearly impossible. A photo that looks perfectly framed on Instagram can end up awkwardly cropped the moment it's reused as a LinkedIn banner or a Twitter header, simply because each platform expects a different shape and resolution. This guide brings together the current recommended sizes for the platforms most people actually use, along with the reasoning behind why these specific dimensions exist in the first place.
The underlying reason sizing matters so much comes down to how each platform actually displays images. Every platform reserves a specific amount of screen space for a given image type — a profile picture, a feed post, a cover photo — and if the uploaded image doesn't match that space's aspect ratio, the platform has to decide how to make it fit. Most platforms solve this by automatically cropping or scaling the image, and that automatic decision rarely centers on the exact part of the photo you intended to be the focal point, which is why a photo can look fine in your files but strange once it's live on the platform.
On Instagram, feed posts are most reliably displayed as a square at 1080 by 1080 pixels, even though the platform now supports some flexibility in aspect ratio for portrait and landscape posts. Instagram Stories use a completely different, much taller shape at 1080 by 1920 pixels, filling the entire phone screen from edge to edge. Profile pictures are displayed as a circle, though the underlying uploaded file is expected to be a square, with the platform applying its own circular mask on top.
Facebook's cover photo, the wide banner-style image at the top of a profile or page, is displayed at 820 by 312 pixels, a notably wide and short shape that rarely matches how most photos are originally framed. It's worth noting that Facebook cover photos are partially covered by the profile picture in the bottom-left corner on most layouts, so important content should be kept away from that specific region.
LinkedIn separates its image requirements between a profile banner and images attached to individual feed posts. The profile banner spans the full width of a profile page at a wide aspect ratio similar to Facebook's cover photo, while feed post images follow a more standard landscape or square ratio. Because LinkedIn is used in a professional context, images that are cleanly cropped tend to be taken more seriously than those left to an inconsistent automatic crop.
On X, formerly Twitter, a profile header image spans the full width of a profile similarly to Facebook and LinkedIn banners, while individual post images are typically displayed closer to a 16:9 landscape ratio in the timeline. Because timeline images are often viewed while quickly scrolling, a clean, properly cropped image tends to catch more attention than one that's been awkwardly cut off by the platform's own automatic preview crop.
Pinterest is unusual among major platforms in that it strongly favors tall, vertical images rather than square or landscape ones, since its masonry-style grid layout gives taller pins significantly more visual space and prominence in search results. A pin at a tall vertical ratio tends to perform noticeably better than a square or landscape image competing in the same feed.
YouTube has two distinct image requirements that are easy to confuse: the channel banner, which spans the top of a channel page at 2560 by 1440 pixels to accommodate everything from mobile phones to television screens, and the video thumbnail, which follows the standard 16:9 widescreen ratio at 1280 by 720 pixels. Because YouTube crops different portions of the channel banner depending on the viewer's device, keeping key branding elements within the platform's known safe area in the center of the banner is essential.
WhatsApp and TikTok both expect a square profile picture, which is then displayed as a circular thumbnail throughout each app. Because the circular display crops away the corners of the uploaded square image, keeping the main subject centered within the square, rather than positioned toward any edge, is important on both platforms to avoid anything important being cut off.
Given how often these exact dimensions change as platforms redesign their interfaces, it's worth treating any specific number as a helpful current guideline rather than a permanent fixed rule. In practice, using a dedicated cropping tool built around each platform's current recommended size, rather than trying to remember exact pixel values from memory, removes most of the guesswork entirely.
ResizerPhoto.in includes dedicated cropping tools for every platform and image type covered in this guide — Instagram posts and stories, Facebook covers, LinkedIn posts and banners, X posts and headers, Pinterest pins, YouTube banners and thumbnails, and WhatsApp and TikTok profile pictures — each one locking the crop selection to the platform's exact current aspect ratio so you can frame your photo correctly and export it at the right resolution in under a minute, directly in your browser.
