Making a new profile on a social media network is how you present yourself to the community (and can also lead to real revenue), so you want to spend your time focusing on things like your bio, developing a “voice” you want to use, and the actual content of your posts. You don’t want to spend three hours resizing your profile picture a hundred times because you can’t get the dimensions right and end up with an image that’s unrecognizable.
Your profile picture is the first thing people see – in those 3 seconds you have their attention they will decide if they want to stick around or move on to the next profile that catches their eye.
This cheat sheet guide contains the most up-to-date dimensions for all the most used social media sites: Facebook, Pinterest, Instagram, Twitter, YouTube, LinkedIn, and Google+. Just save this image to your computer and use it whenever you take the leap and join a new social networking site.
