Fonts are Actually Called Typefaces
It takes at least a few minutes to alter the font of a headline if you've ever done any design work on a computer, even something as easy as drafting an essay for school. Numerous fonts are available in Microsoft Word and other software like PhotoShop. You can use fonts from Stranger Things, Harry Potter, Star Wars, or simply some timeless and simple styles that resemble newspaper headlines or even calligraphy. Font options are countless. None of them are typefaces either.
The term "font" especially refers to the differences seen within a single typeface. That refers to the letters' height or width. It does not allude to the evident design variation between each set of letters, which distinguishes Star Wars from Harry Potter. Actually, that is the typeface.
Most creative types are already aware of this. However, font and typeface are synonymous terms in the general public. This is so that software may simply call typefaces and fonts. In a design software, the word "typeface" is seldom ever used. If you make something bold or modify the size going forward, you're changing the font, to be more precise. If you convert from Arial to Times New Roman, you are altering the typeface.
