Subject:Review of research on graphic text design From:Stuart Burnfield <slb -at- FS -dot- COM -dot- AU> Date:Wed, 16 Apr 1997 06:59:57 +0800
Dick Miller posted the following summary to the UTEST list last month.
I asked Dick if I could forward this to TECHWR-L, as type issues are
a hardy perennial here, and he agreed. I thought this might be useful
as it's clearly presented *and* has references, unlike 90% of the
flameb... er, opinions that usually gets posted.
You don't have to agree with all these findings (in fact it would be
a worry if you did, as some of them are contradictory) but at least
you have the opportunity to chase them down to their source.

Subject: Type case redux
In searching my files, I came across the following information that
seems pertinent to the earlier thread on type cases, and thought I
would post it for those who are interested.
Review of research literature on graphic text design
Some research indicates that readers can read serif typefaces more
quickly than sans serif, but other research indicates little
difference in legibility.
Ragged right margins do not adversely affect legibility. In fact,
full justification reduces poor readers' performance. Variable-
spaced, full-justified text improves reading speed. A contradictory
finding was that full-justified text does not benefit skilled
readers. Large, unpredictable spaces between words and at the end
of sentences reduce reading speed.
Kerning and letter spacing
Readers read more text in a given period when letters are close set.
Smaller type with leading is not more legible than larger type set
Ten to twelve words per line, or about fifty to seventy characters,
is the optimal line length for most conventional type sizes.
Nine- to eleven-point type promotes faster reading.
Indenting the first line of a paragraph improves legibility.
Uppercase versus lowercase
Text set in lowercase letters is read ten percent faster than similar
material set in all capitals. Text set in all capitals is read about
nineteen percent slower than text set in mixed case. Capitalizing
every letter of individual words makes it easier for readers to
Boldface type is the most salient way of highlighting words or short
portions of text.
Italic print is read more slowly than roman lowercase.
