GCM 230
Week 3
Readability: the ability to read text over a sustained period of time
Is largely determined by the person executing the page layout or
typographic setting
oIs affected by the choice of typeface, size, leading,
letterspacing/tracking, white space, measure, indents, alignment and
other typographic factors
Is our ability to recognize the individual letterforms in a typeface
Is initially determined by the type designer
oHowever, a legible typeface can be ruined by a typographer, graphic
artist, or page designer who does not treat the type with respect
Some faces are not designed with legibility in mind
oUsed primarily for titles and NOT for text
Leading: the distance between one baseline of text to the next baseline of
oLeading is ALWAYS measured in points
oLeading should NOT be confused with line spacing
Factors that affect leading:
oSerif or sans serif type
oTypefaces that have very long ascenders or descenders (e.g. Papyrus)
oType set in ALL CAPS (therefore no ascenders and descenders)
There are 6 types of leading one should be aware of
oDefault leading: 1.2 (constant) times the body size
E.g. 10 pt type  10 x 1.2 = 12 pt leading  (10/12)
oPractical Leading: 2.5 times the x-height
oClassical Leading: 3 times the x-height
oSet Solid: the leading value is the same size as the body size
oNegative leading: the leading value is less than the body size
oToo much leading: the leading value is much greater than the body
