So you just designed that awesome graphic for your new product/service/announcement and you’re about to post it to the Twitter-verse. Well, you can’t just grab it from Facebook or Instagram and splash it on to Twitter. Every Social Network has its special rules and nuances, and Twitter is no exception.
On Twitter, your picture has the most optimal display when created in the 2:1 (W:H) ratio. This means that if the width of the photo is 600 pixels, then the height must be 300 pixels. You dig?
In other words, the width must be 2 times the height. Consider the BAD example below.
In the above example, the graphic shows no respect for Twitter’s display, and is therefore cropped by default. This means that your followers would need to expand the tweet to view the whole thing.
Life is too short for that, so most people would just keep scrolling with whatever fraction of your content they were able to visually capture.
What you need, is a graphic that captures the entire message at first glance as shown below.
