Some of you may not agree with some of these ideas, particularly the height in pixel. We saw recently an infographic which is more than 9000 px tall. This is totally insane in our view.
As for text, too many people use infographics as they use Word. "Infographic" contains the word "graphic" for a good reason. IF you need to use text, use text and add some images in your HTML or PHP or whatever, page. We wrote a post about mediocre infographics in French..
The translation of this infographic may be not perfect, but it contains such a typical fragrance of french content marketing that we will leave it as is. Thanks for your understanding.
