Adioma templates are optimized to fit maximum text without sacrificing readability and without violating the principles of composition. Our experience with publishing infographics shows that infographics with short text fields by far outperform those with large text blocks.
If you need to tweak the text a bit to make sure a word you must have fits, you can do so by changing the font size. 

You can change the font size right below the title field.
​

The small "A" makes the font size smaller, the larger "A" makes the font size larger.
