How do we know?
Each site was opened twice in a real browser and Chrome was asked which font file drew each piece of text. We count a font for a site only if both runs saw it and it drew at least 2% of the site’s custom-font text. The full method. Klim sells Calibre; its page links to buying the fonts and to its font licences page.
