The Facebook thumbnail has become the latest social media irritation.

At first we did not understand how to go about fixing the issue that we had with one Facebook thumbnail displaying tiny and another being nice and big.

You know this by now, but for effect we’ll repeat it. We are a digital agency based in Durban. That means that social media is one of the service we offer our clients. So being a social media service provider means we have to stay on top of what’s happening in the social media space all the time. But this Facebook thumbnail issue was really starting to frustrate the hell out of our social media team. Every time we posted with an image it looked like this:

How to make your Facebook thumbnail stand out

And for weeks we tried figuring out why exactly this happens. And because we work with different clients, who have different websites with different layouts, the images always differed. They were never the same size in width or height. So we just assumed that the Facebook thumbnail is something that is driven by some type of Facebook algorithm and every umpteenth image posted on Facebook shows a nice big and visible thumbnail.

Oh how wrong we were about the Facebook thumbnail.

It was on this last public holiday, Monday June 16 that we did some prerequisite reading and stumbled upon the blog of Jon Loomer – a remarkable Facebook marketing whiz. And Jon explains meticulously that Facebook turns low resolution images that has a width of less than 600 pixels and a height of less than 315 pixels into a tiny thumbnail. In fact Facebook recommends that all images you upload into a post be at least 1200 pixels wide and 627 pixels high for it to display as a nice big and visible Facebook thumbnail. Jon has a nice Facebook thumbnail and image upload size guide you can find on his website. In fact we have unknowingly been uploading images that are 650 pixels wide and they all displayed like this:

So anything less than 600 pixels wide WILL display as a teeny tiny Facebook thumbnail and every image larger will be considered a high resolution image and will display large and visible. This is also meant for display on mobile and other high resolution devices – hence the display size.

So as of this past Monday – now that we know what size images to use – we are officially no longer mad about the way the Facebook thumbnail displays.
