Font doesn’t mean typeface: a font is all the characters of a particular typeface in a specific type size. M & H Type in San Francisco have drawer after drawer of different fonts waiting for someone to order say 14pt Garamond or 9pt Helvetica. We purists should of course just give up: the word font is really now effectively synonymous with typeface. If people say it is so, then it is so. Language evolves. Such is the power of the computer; after all if Apple can round off the points system to make 72 points exactly equal to an inch, why can’t they make font mean typeface?
This info graphic (delivered via The Digital Reader) does briefly address this “confusion”. Can the assertion that sans serif typefaces are better suited to on-line be anything more than a prejudice? — A prejudice perhaps which landed us with Google’s new and ugly logo.
