Those metrics without loss of content or functionality. Rather, it specifies that an author's content has the ability to be set to This SC does not dictate that authors must set all their content to the specified For example, a user may need to change to a widerįont family than the author has set in order to effectively read text.

The specified metrics set a minimum baseline. Text styling can be adapted by the user to suit their needs.

Fonts intended for body text have spacing optimized for body-text point sizes (approximately 9–13 point). I accept the minority view on Goudy’s comment because, as Goudy was doubtless aware, sometimes lowercase should be letterspaced. But a few sources claim that his original comment concerned blackletter fonts, not lowercase, and that he used a more colorful verb than “steal”. Typographer Frederic Goudy is famously credited with opining that “Anyone who would letterspace lowercase would steal sheep”. ![]()
