Some people might say that content is just about coming up with valuable & informative ideas for your audience, right?

‍

WRONG 😠

‍

Knowing how to optimise your content for each platform puts you one step ahead of other brands, as it makes you & your brand more credible & trustworthy because it shows that you know what you’re doing when it comes to social media marketing (plus, your assets won’t look like you hastily pulled them together during an all-nighter 😉)

‍

Our guide breaks down the best social media sizing for profile pictures, headers, image sizes, videos & more for the biggest social media platforms for 2025, so you can be in the know & ready to go 🚀

‍

In order, we’ll be covering the social media sizes for X, Bluesky, Facebook, Instagram, TikTok, LinkedIn, YouTube, Twitch, Reddit & Discord. 🤳

‍
