Have you heard what Meta recently reported? About 82% of people visiting video-centric platforms—such as TikTok, Facebook, Instagram, and Youtube—are visiting from a mobile device. That means about 82% of people are viewing content on a vertical screen and holding it upright on their phones (and likely inches from their faces)!
How can we make sure our posts are neatly fitting into those rectangular screens to be optimized for each platform? Well, first, we can start off by simply creating the right size post!
Our experts break down the best Facebook, Instagram and TikTok post dimensions and sizes for each platform in this easy-to-follow Social Media Image Sizes Guide.
Of all the platforms, Facebook is the wildcard due to its split age-group audience of viewers. Many people use desktop, many people use mobile devices!
Try creating a mix of content that’s optimized for both desktop (horizontal) and mobile (vertical) to see which performs best with your audiences.
Pro Tip: Alternate dimensions of Facebook Lives—film some on phones to tour your store and displays, and film others horizontally to showcase particular items or answer a Live Q&A!
Instagram is currently testing a 4:5 aspect ratio feed which means posts will appear in a taller rectangle vs a square. We suggest that IG posts be optimized for an image/post size of 1440 pixels x 1152 pixels tall (16″ wide x 20″ tall). This means the post will take up more vertical space on a phone in the feed and supports rumors of a “full-screen” (mobile-first) feed (where most/all posts will appear full screen, similar to Stories and Reels).
Pro Tip: Film Reels and Stories in full-screen and always film vertically (omitting a black border around your content) to be optimized for a mobile-first viewing!
I don’t know about you, but I’ve only ever opened TikTok on my phone! Be sure all content filmed and uploaded for this platform is full screen and vertical!
What I Want You To Take Away From This Blog:
- Test your social media image sizes to see what works best for your audience.
- Lean into full-screen content.
- Optimize for mobile viewers.
Okay, over to you…

We’d also love to know in which social media image sizes you prefer to view content. Mine is most definitely full screen through Stories and Reels!
