Sizes & Requirements

Each social media network will have its own requirements for what kind of content they allow.

While you might have found a happy medium that works for you brand by now, it's important to be aware of the limitations and possibilities when experimenting with new types of posting.

Below we have listed the specific requirements and limits for each of the social media networks you can post through via SocioConnect.

Facebook

For optimal visibility, Facebook posts should aim for 1200x630 pixels with a 1.91:1 aspect ratio.

Square images (1080x1080) and portrait images (1080x1350) are also suitable.

The maximum file size for shared images is 8MB.
