Replacing the font in a template is extremely easy. Just find the ‘Font’ list in the Customization tab of the editor sidebar, and change the fonts to your liking. You will get the option to choose from thousands of Google Fonts (available in all languages), upload your own brand font, or leave the original font the author used.
Fonts are a substantial part of every brand. When you are building a brand, there are certain elements (font, logo, color palette, tagline, positioning, imagery, etc) that must be defined to create a clear brand personality. Just like getting to know a person, as a result of these elements working together, your brand will be loved (or not).
An important element of any brand - fonts establish your brand’s identity and mark. They are a powerful tool which distinguish you from the competition and help form associations in people’s minds that reinforce brand recognition.
In addition, fonts convey the mood and tonality of conversation. For example, the Walt Disney script gives off a light and joyful mood, while the New York Times' English Towne font establishes a serious tone. The font style you choose has a strong impact on how a message will be perceived.
Hope this article was helpful in understanding the importance of branding and choosing the right font (if you still haven’t) as a substantial part of brand communication. In case you are still not convinced, I'll just leave this here. Cheers!
