The Definitive Social Media Image Size Guide (2026)

You spend hours crafting the perfect photograph or graphic design, only to upload it to Instagram and realize they awkwardly cropped out the most important part. Or worse, you upload your company logo to LinkedIn, and it turns into a blurry, pixelated mess.

Every social media platform has its own wildly different, constantly changing set of rules for image dimensions and aspect ratios. If you upload an image that does not perfectly match their specifications, their aggressive internal compression and auto-cropping algorithms will destroy your image's quality.

To maintain a professional, high-quality digital presence, you must prepare your assets correctly. This guide provides the exact pixel dimensions you need for every major platform right now.

Instagram Image Sizes

Instagram is fundamentally a visual platform. It is notoriously strict about aspect ratios. If your image doesn't fit the 1:1, 4:5, or 16:9 molds, it will be mercilessly cropped.

• Profile Picture: 320 x 320 pixels

  Displays circularly at 110x110 on mobile. Ensure the focal point of your logo or face is dead center so it doesn't get clipped by the circular mask.

• Square Post (1:1 Ratio): 1080 x 1080 pixels

  The classic Instagram format. Ideal for carousels and grid aesthetics.

• Portrait Post (4:5 Ratio): 1080 x 1350 pixels

  Highly recommended by marketers! Portrait posts take up maximum screen real estate on mobile phones, making it harder for users to scroll past your content.

• Instagram Stories & Reels: 1080 x 1920 pixels

  Leave the bottom 250 pixels and the top 250 pixels clear of important text, as Instagram UI (comments, swipe up, bio) will cover these areas.

Facebook Image Sizes

Facebook constantly redesigns its interface, so uploading high-resolution baseline images is critical to survive downscaling.

• Profile Picture: 170 x 170 pixels minimum

  We recommend uploading a much larger 1080 x 1080 pixel image so it looks crisp when users click to expand it.

• Cover Photo: 820 x 312 pixels

  Displays highly variably between desktop (820x312) and mobile (640x360). Keep all important text in the central "safe zone" of 640x312.

• Shared Post Image: 1200 x 630 pixels

  The ubiquitous 1.91:1 ratio. This is also the exact dimension you should use for your website's Open Graph (OG) meta tags when links are shared on Facebook.

Twitter (X) Image Sizes

Twitter is notorious for harsh image compression. If your image contains text, always convert it to PNG format using our Format Converter before uploading to prevent compression artifacts.

• Profile Picture: 400 x 400 pixels (Displays circular).
• Header Image: 1500 x 500 pixels. Account for your profile picture covering the bottom-left corner of the header!
• In-Stream Photo: 1600 x 900 pixels (16:9 ratio). Previously Twitter heavily cropped preview images, but now mostly respects the uploaded ratio. However, 16:9 is safest for maximizing click-through rates.

LinkedIn Image Sizes

LinkedIn is your digital resume. Blurry images here immediately communicate a lack of professionalism to potential employers or clients.

• Personal Profile Picture: 400 x 400 pixels (Maximum 8MB).
• Personal Background Cover: 1584 x 396 pixels.
• Company Logo: 300 x 300 pixels.
• Company Page Cover Image: 1128 x 191 pixels (Extremely wide crop).
• Shared Link / Article Image: 1200 x 627 pixels.

YouTube Image Sizes

A compelling thumbnail is 90% of a video's success metric. Viewers judge the quality of a video by the sharpness of its thumbnail.

• Channel Profile Image: 800 x 800 pixels.
• Channel Banner Image: 2560 x 1440 pixels. This displays across TVs, Desktops, and Mobiles entirely differently. The "Safe Area" for text and logos is the dead center measuring 1546 x 423 pixels.
• Video Thumbnail: 1280 x 720 pixels (Must be under 2MB).

Workflow: From Raw Photo to Social Ready

To ensure you never upload a bad image again, follow this quick checklist before you hit publish:

1. Find the correct dimensions for your target platform in the guide above.
2. Open the ResizeMe Resizer Tool and input the dimensions.
3. If the platform has strict size limits (like YouTube's 2MB thumbnail limit), quickly pass the resized image through the Image Compressor.
4. Ensure you are using the correct file type. Use our Image Format Guide to decide if you need a JPG or a PNG.
