Media Cheat Sheet – Up-to-date social media image and video sizes

Hi HN!

I’ve built MediaCheatSheet.com – a simple, no-nonsense reference tool that collects the latest social media image and video dimensions in one place.

It’s designed for designers, content creators, and marketers who are tired of constantly Googling “Instagram reel size” or “Twitter post image ratio.”

There are no ads, trackers, or logins – just the specs you need, organized by platform. It’s free to use, and I plan to keep it regularly updated.

Would love your feedback, suggestions, or ideas for what to add next!

Thanks! Ronalds
