Well, experts say it is important for several reasons. First, is consistency. It is crucial for brand recognition since using a simple font helps create a uniform and recognizable visual identity for your business. Two, is professionalism. A array of varying fonts creates a disorganized and less credible look and no one in business wants that. Third, choose a font that is clear and easy to read. If someone can’t easily read the font your using, they will be unlikely to keep on reading and will move on to the next business.
Of course, if you do a bit of research on your own, you will find there are many more than three reasons to use the same font but these three are the ones that stand out the most to me.
