📱 Social Media Image Resizer: Perfect Sizes for Every Platform

Learn the exact image dimensions needed for Instagram, Facebook, Twitter/X, LinkedIn, and other platforms, and how to resize accordingly.

Every social media platform has its own preferred (and sometimes required) image dimensions for posts, profile pictures, and cover photos. Uploading an image with the wrong dimensions often results in awkward cropping chosen automatically by the platform — controlling the exact size yourself produces much better results.

Common Platform Dimensions (General Guidelines)

Platform Content Type Typical Size
InstagramFeed post (square)1080×1080px
InstagramStory/Reel1080×1920px
FacebookFeed post1200×630px
FacebookCover photo820×312px
Twitter/XIn-feed image1600×900px
LinkedInFeed post1200×627px
YouTubeThumbnail1280×720px

Note: Platforms update their specifications periodically — always check the platform's current official guidelines for the most up-to-date dimensions before an important post.

Why Correct Sizing Matters

  • Avoids automatic cropping: Uploading the wrong aspect ratio often means the platform auto-crops your image, potentially cutting off important content (like a person's head or key text)
  • Prevents pixelation: Uploading an image smaller than the platform's display size results in a blurry, stretched appearance
  • Faster upload and better quality display: Correctly-sized images upload faster and display exactly as intended, without the platform's own re-compression introducing additional quality loss

General Tips

  • Design for the smallest common view: Since images display differently across feed, mobile, and desktop views, keep important content (faces, text) centered and away from edges
  • Save a master high-resolution version: Keep an original, larger version of your image before resizing down for each platform — resizing up from a small image later will lose quality

❓ Frequently Asked Questions

What size should an Instagram feed post be?
A square 1080×1080px is the standard size for Instagram feed posts. For Stories or Reels, use 1080×1920px (vertical, full-screen format). Always check Instagram's current official specifications, as they can update over time.
Why does my image get cropped weirdly when I post it to social media?
This happens when your uploaded image doesn't match the platform's expected aspect ratio — the platform automatically crops it to fit, which can cut off important content like a person's head or key text. Resizing to the platform's exact recommended dimensions before uploading prevents this.
Should I keep a high-resolution master copy of my images?
Yes — always keep an original, larger resolution version before resizing down for each specific platform. If you need a different size later, resizing down from a high-resolution master preserves quality much better than trying to enlarge a smaller image after the fact.
Do social media image size requirements change over time?
Yes, platforms periodically update their recommended and required dimensions as they add new features or redesign their interfaces. Always check the platform's current official guidelines before an important post if precise sizing matters.
