Image Guidelines for Social Media Posts

Social media posts that include images can be created through the LinkedIn and X (Twitter) connectors using the Social Publish feature. You can also share your Act-On assets directly to Facebook.

Below are some guidelines for the use of images when posting on X (Twitter), LinkedIn, or Facebook:

X (Twitter)

• The minimum image size is 600 x 335 pixels. Larger images (e.g., 1152 x 648 & larger) will look nicer when users click to expand them.
• Recommended aspect ratio is 16:9, but anything between 2:1 and 1:1 will work. If the height exceeds the width of the image, it is cropped at a 1:1 ratio.
• The avatar should be 400 x 400 pixels.

LinkedIn

• Large images cannot be shared outside of the LinkedIn platform, & any image asset shared must be associated with a shared URL.
• You may change the Thumbnail image after selecting a URL to share.
• Thumbnails should be 400 x 400 pixels.

Facebook

• Images should be 1200 x 630 pixels.
• The minimum image size is 600 x 315 pixels.
• The avatar should be 180 x 180 pixels.
