Page Design
One rule to know when designing documents is keep it simple.
Avoid cluttering your documents with unnecessary font changes.
It takes experience and talent to skillfully blend a wide range of
typefaces.
Always consider your reader first. Select a typeface that’s best for
your particular document and consider the meaning of your words.
What are you trying to communicate? A strong, no-nonsense
typeface, like Helvetica, proclaims its message loud and clear. This
is why sans serif type is often used for signs, like NO PARKING.
Helvetica is considered so strong it does not even have a true Italic
form, since Italic forms convey grace.
Skillful typeface use in page design also increases readability as
well as legibility. Newspapers are a good example of readability.
Typeface chosen for text and headlines varies in size, and text is
contained in columns two to three inches wide. Thus the eye does
not have to travel far and the reader does not lose his place.
Other aspects of design such as word spacing (justified vs.
unjustified), line spacing, letter spacing within words, upper case
and lower case letters, all affect legibility.
Many books are available on page layout and design as well as
typography. Many words have meanings that apply only to
typography. (See figure 5.9 for some of them.) However, page
design has no set rules. If you design a document and don’t have
time to study the craft, remember the rule: keep it simple.
