Every social media platform has a different array of images needed in order to set it up properly. The common thread is that they don’t often list the size image needed until you are already into the upload process.
Since several of my students and clients recently have requested this info (Hi Marcy!) I’m posting it here where it can be the most accessible for everyone. The infographic is the work of the bold folks over at LunaMetrics. I’d like to thank them for making it freely share-able!
