About Social Media Size Guide
The Social Media Image Size Guide is a comprehensive reference tool that covers exact pixel dimensions and aspect ratios for every major content type across Instagram, Facebook, X (Twitter), LinkedIn, YouTube, and TikTok. Whether you need the dimensions for an Instagram Feed Post (1080×1080 at 1:1), a LinkedIn Cover Photo (1584×396 at 4:1), a YouTube Channel Art (2560×1440), or a TikTok In-Feed Ad (1080×1920), all values are organized by platform and content type for quick lookup.
This tool is used daily by graphic designers sizing Figma or Photoshop canvases, social media managers creating content calendars, marketers setting up ad creatives, and content creators who need to quickly verify dimensions before exporting. Having the correct dimensions is critical because uploading undersized images results in quality loss from upscaling, while incorrect aspect ratios cause unwanted cropping at the platform level — both of which reduce visual impact and engagement.
The tool renders a small visual preview box beside each size entry that is proportionally scaled to the actual aspect ratio, giving users an intuitive sense of the image shape before they start designing. Clicking the "Copy" button beside any size entry copies the dimensions (e.g., "1080 x 1920") to the clipboard instantly, so they can be pasted directly into design tools without manual typing.

Frequently Asked Questions
What is the correct size for an Instagram Feed Post?
Instagram Feed Posts support three aspect ratios: Square (1080×1080, 1:1), Portrait (1080×1350, 4:5), and Landscape (1080×566, 1.91:1). The portrait format (4:5) takes up the most vertical real estate in the feed and generally performs best for organic reach. Instagram also supports Carousel posts (up to 10 slides) using the same 1:1 square format.
What size should I use for Instagram Stories and Reels?
Instagram Stories and Reels both use a 9:16 vertical format at 1080×1920 pixels. This is the full-screen vertical format optimized for mobile viewing. When designing, keep key visual elements and text within the center safe zone (approximately 1080×1420) to avoid overlap with the UI interface elements at the top and bottom of the screen.
What are the correct dimensions for a YouTube thumbnail?
YouTube thumbnails should be 1280×720 pixels (16:9 aspect ratio). This is the standard HD format that displays correctly across all devices. YouTube recommends keeping file size under 2MB and using JPG, GIF, BMP, or PNG format. For YouTube Channel Art (banner), use 2560×1440 pixels, but design with a safe zone of 1546×423 pixels centered to ensure the content is visible across all devices.
What image size does LinkedIn use for profile and cover photos?
LinkedIn Profile Photos are displayed at 400×400 pixels (1:1). The LinkedIn Cover Photo (background banner) is 1584×396 pixels (4:1). For Company Pages, the logo is 300×300 pixels and the Life Tab Hero image is 1128×376 pixels. Blog Post images shared on LinkedIn feed use 1200×627 pixels (close to 1.91:1).
What is the best image size for a Facebook Cover Photo?
Facebook Cover Photos display at 820×312 pixels on desktop and 640×360 pixels on mobile. The recommended upload size is 820×312 pixels (2.63:1 ratio), but uploading at 1640×624 for retina displays is a good practice. Facebook Feed Posts use 1200×630 (1.91:1), while Event Covers use 1920×1005 pixels.
What dimensions are used for X (Twitter) images?
X (Twitter) In-Stream Photos use 1600×900 pixels (16:9). Profile Photos are 400×400 pixels (1:1) and Header Photos are 1500×500 pixels (3:1). Twitter Card Images (used in link previews) are 800×418 pixels. When posting multiple images in a single tweet, Twitter crops each image differently depending on the count — two images use a 7:8 ratio per image.
Why do image dimensions differ between platforms?
Each social media platform has its own feed layout, screen density targets, and content philosophy. Instagram prioritizes portrait content for mobile-first browsing, while LinkedIn caters to desktop users with landscape-heavy formats. YouTube is built around 16:9 widescreen video. TikTok, like Instagram Stories, is 9:16 vertical. Using platform-specific dimensions ensures images are displayed at the highest quality without unwanted cropping or compression artifacts.
What happens if I upload an image with the wrong dimensions?
If you upload an image that is too small, the platform will upscale it, which causes blurriness and pixelation. If the aspect ratio is wrong, the platform will center-crop the image to fit its expected ratio, which may cut off important parts of your image. For example, uploading a 16:9 image to an Instagram portrait slot will result in significant top and bottom cropping. Always design to the exact dimensions for each platform and content type.
