Why image sizes matter for engagement

Every social network crops uploads that don’t match its preferred aspect ratio. The wrong size means your caption gets cut off (Instagram), your CTA disappears behind UI (TikTok, Reels), or your thumbnail looks blurry in search results (YouTube). Matching the exact pixel dimensions below gives the algorithm the full image it expects, and the algorithm rewards complete, high-fidelity uploads with more reach.

In 2026, every major platform has moved toward a 9:16 vertical-first experience for short video (Reels, Shorts, TikTok, Pinterest Ideas, Facebook Reels). If you only produce content at one ratio, 9:16 reaches the most people. For feed posts, 4:5 portrait (1080 × 1350 px) still tops 1:1 square on Instagram, Threads, and LinkedIn because it occupies more screen real estate on mobile.

YouTube is the outlier — long-form videos and thumbnails are still 16:9 and haven’t budged. Keep thumbnails at 1280 × 720 px under 2 MB so they render instantly even on slow mobile connections.

Frequently Asked Questions

Is this image size guide kept up to date?

Yes. We review this reference at least every quarter and whenever a platform (Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, or Threads) publishes a new size spec. Last major review: 2026.

Why do social networks change their image sizes so often?

Sizes change for three reasons: new aspect ratios (Reels and Shorts pushed 9:16 everywhere), mobile-first redesigns, and ad-unit updates. Using the wrong size causes cropping, blurriness, or rejected uploads — our guide lists the current pixel-perfect dimensions for each placement.

What's the best all-purpose size for social media posts?

1080 × 1350 pixels (4:5 portrait) is the safest single-size upload for Instagram, Threads, Facebook, LinkedIn, and Pinterest feeds. For Stories, Reels, Shorts, and TikTok use 1080 × 1920 (9:16). YouTube thumbnails still need 1280 × 720 (16:9).

Do I need separate images for Stories and Reels?

Same aspect ratio (9:16), same resolution (1080 × 1920), so the same image works — but leave 220 pixels of safe zone at the top and bottom to avoid having UI overlays (profile, captions, CTAs) cover your content.
