The fifth of five rules in Matthew Butterick’s “Typography in Ten Minutes”:
And finally, font choice. The fastest, easiest, and most visible
improvement you can make to your typography is to ignore the fonts
already loaded on your computer (known as system fonts)
and the free fonts that inundate the internet. Instead,
buy a professional font (like those found in font
recommendations). A professional font gives you the benefit
of a professional designer’s skills without having to hire one.If that’s impossible, you can still make good typography with
system fonts. But choose wisely. And never choose Times New
Roman or Arial, as those fonts are favored only by
the apathetic and sloppy. Not by typographers. Not by you.
