Quick challenge: Do you know …

• What are the image dimensions for cover photos on LinkedIn pages? How about Facebook, YouTube and Google+ photo dimensions?
• How many characters can a  LinkedIn post contain without getting truncated and cut off in followers’ news feeds?
• Does your Facebook profile photo (that’s the little one that displays as your icon in news feeds) display at the same size that you upload it?
• Photos you share on Facebook can display at any of three sizes in the news feed. What are they?

To be honest: I don’t know all of the answers off the top of my head. I don’t need to. I can always look them up when needed.

But HubSpot just made it a lot easier – for me and for you.

If you work in social media, or support people who do, you want to see this infographic that HubSpot just published: The Ridiculously Exhaustive Social Media Design Blueprint. It shows image dimensions, display sizes and text limits for various types of posts and branding content on LinkedIn, Facebook, Pinterest, YouTube, Google+, Instagram and Twitter.

One caveat: These are for the primary desktop displays of each social network. There’s nothing specific to spell out differences on mobile, tablet or app displays. But that’s not a complaint, and it doesn’t mean this won’t help you. It will.

Thank you, HubSpot, for making our lives a little bit easier.
