Can all fonts be used in a presentation equally? It turns out no. If you are making a presentation for public speaking, then you should not choose serif fonts (or serif). Typical representatives are Times New Roman, Courier New or Cambria. The fact is that in such fonts, small dashes - “serifs” are placed on the top and bottom of the letters. And at a distance, the letters simply merge into a single mass, making it difficult to read the text.
Such fonts are ideal for printing large amounts of text, because when reading, serifs help to “hold” the line. But for performances, choose the non-serif fonts, for example, Arial or Calibri. Although we prefer to be limited to the non-serif fonts in most cases. Even if the presentation is sent to the partner by e-mail, it is possible that he decides to view it on the projector. So exclude Times New Roman and the like from your arsenal.
