Posting images on social media? Make sure they're the right size. Here's the definitive guide to image dimensions for every major platform.

Perfect Image Sizes in 2026

Platform	Ideal Size	Use
Facebook Cover	820×312	Profile page banner
YouTube Thumbnail	1280×720	Video preview
Instagram Square	1080×1080	Regular posts
Instagram Story	1080×1920	Stories & Reels

Why Size Matters

Platforms automatically crop and scale images. If your image is the wrong size, you lose key content or look unprofessional.
