Chars Arial Lines


60 Contemporary sans serif design, Arial contains more humanist
73 characteristics than many of its predecessors and as such is more in tune
72 with the mood of the last decades of the twentieth century. The overall
75 treatment of curves is softer and fuller than in most industrial style sans
74 serif faces. Terminal strokes are cut on the diagonal which helps to give
70 the face a less mechanical appearance. Arial is an extremely versatile
73 family of typefaces which can be used with equal success for text setting
64 in reports, presentations, magazines etc, and for display use in
69 newspapers, advertising and promotions. Features: Arial contains 1674
71 glyphs and 909 standard kern pairs. This font does not include embedded
71 bitmaps. Font designer: Monotype Type Drawing Office - Robin Nicholas,

Chars Calibri Lines


81 Calibri is a modern sans serif family with subtle roundings on stems and corners.
80 It features real italics, small caps, and multiple numeral sets. Its proportions
82 allow high impact in tightly set lines of big and small text alike. Calibri's many
79 curves and the new rasteriser team up in bigger sizes to reveal a warm and soft
80 character. Features: Calibri contains 1121 glyphs and 14148 standard kern pairs,
73 see below for OpenType kern pair information. This font includes embedded
76 bitmaps. Font designer: Luc(as) de Groot. © 2006 Microsoft Corporation. All
