As a visual creator, I kept wasting time searching “Instagram Reel size” or “YouTube thumbnail ratio” before posting. So I built MediaCheatSheet.com — a clean, searchable directory of up-to-date image and video dimensions for all major social platforms.

Includes SVG templates with safe zones — ready to download and use in your workflow

Quickly copy direct links to sizes — great for sharing with clients, editors, or designers

Covers Facebook, Instagram, YouTube, TikTok, LinkedIn, X/Twitter, Reddit, and more

Free, minimal, and regularly updated (no login or fluff)

Free, minimal, and updated regularly.

Hope it helps others here who juggle multiple platforms. Feedback welcome!
