Open Sans

Open Sans is a sans-serif typeface designed by Steve Matteson and commissioned by Google. According to Google, it was developed with an "upright stress, open forms and a neutral, yet friendly appearance" and is "optimized for legibility across print, web, and mobile interfaces."

The Open Sans font is currently the default typeface for Mozilla software. Like Roboto, Open Sans is considered a “humanist font,” as it was developed using oval shapes and stroke variations that give it a more human, familiar feel.
The Open Sans font consists of 10 styles: 300, 300italic, regular, italic, 600, 600italic, 700, 700italic, 800, 800italic and 7 charsets: greek-ext, cyrillic, vietnamese, greek, latin, cyrillic-ext, latin-ext.
This free typeface was designed with an upright stress, open forms and a neutral, yet friendly appearance. It was optimized for print, web, and mobile interfaces, and is incredibly legible.


Arial is a neo-grotesque typeface: a design based on the influence of nineteenth-century sans-serifs, but made more regular and even to be more suited to continuous body text and to form a cohesive family of fonts.

Arial, sometimes marketed or displayed in software as Arial MT, is a sans-serif typeface and set of computer fonts. The Arial typeface was designed in 1982, by Robin Nicholas and Patricia Saunders, for Monotype Typography.
The Arial typeface comprises many styles: Regular, Italic, Medium, Medium Italic, Bold, Bold Italic, Black, Black Italic, Extra Bold, Extra Bold Italic, Light, Light Italic, Narrow, Narrow Italic, Narrow Bold, Narrow Bold Italic, Condensed, Light Condensed, Bold Condensed, and Extra Bold Condensed.
Arial contains more humanist characteristics than many of its predecessors and as such is more in tune with the mood of the last decades of the twentieth century. The overall treatment of curves is softer and fuller than in most industrial style sans serif faces.
