If you've ever stopped mid-workflow to Google "Facebook story ad dimensions" or "LinkedIn image size 2024", you're not alone. It's one of those small, recurring frustrations that adds up — especially when you're juggling campaigns across multiple platforms at once.

So I fixed it. Today I launched Ad Specs — a free, dedicated cheat sheet hub covering every major ad platform in one place.

Each platform gets its own page with clean, comprehensive specs: image sizes, video dimensions, file format requirements, character limits, and aspect ratios — everything you need to build compliant creatives without hunting through developer docs or outdated forum posts.

Get ad specs for the following platforms:

Facebook

Instagram

Google

YouTube

LinkedIn

Pinterest

Snapchat

X (Twitter)

Amazon

No sign-up required. No paywall. Just the specs, whenever you need them — bookmarkable, shareable, and always ready.

Whether you're a solo founder putting together your first campaign or a seasoned media buyer spinning up a new platform, Ad Specs is the reference page we always wished existed. Consider it yours.
