Social Creative Spec Sizes for 2021

Social platforms are always evolving to adapt to new trends and UI. With that, formatting and sizing your creative for each platform is ever-changing.

Wondering what sizes you should be using for your ad creative in 2021? We’ve put together a handy guide to all the current social creative spec sizes. Whether you are looking to create a new profile cover for your business, or want to know what the best size for your video on Instagram is, we’ve put together some best practices to make the most out of your social assets.

Important Note: Ensure your creative is mobile-first friendly

In the last few years, there has been a significant shift from desktop browsing to mobile. According to BackLinko, the current mobile vs. desktop share worldwide is weighted towards mobile with 53.81% of people accessing the internet, with 78% of those users exclusively accessing social media on mobile. And with this, businesses should ensure that their creative is optimized accordingly. Making your social assets mobile-first will allow you to capitalize on a smartphone’s real estate. For example, rather than formatting an image as landscape, you will want to focus your efforts to design your creative to be portrait format.

When creating video content for social, be sure to also consider adding closed captioning, or subtitles to your content, as most social platforms don’t have audio prompted to play automatically on mobile, or desktop.

If you are creating a long-format video on Facebook, it is still okay to go with 1920px by 1080px (16:9) dimension, as videos will take full screen when a mobile phone is turned side-ways.
