To add a heading, you can click the "H" button in the top right corner.
To fit more text, you can click on the smaller "A" button several times. We optimized the text area size for scan-ability which is the main design factor in maximizing the chances that people reading the infographic will read the text. Simply put, keeping the text areas small in relation to images and white space pays off - people will read the text.
