LINE WIDTH AND TYPE SIZE
As for column width, try not to have more than 45 characters per line,
including spaces and punctuation in double-column format; anything
above that tends to give a ‘stringy’ look. If the copy is set across the page,
aim for between 70 and 80 characters per line. But remember that lines
with only a few characters, those that run round a photograph or display
heading for example, will be awkward to read and look messy.
Be careful when considering the relationship between line length and
type size. Much will depend on your design objectives and the purpose of
your printwork. As a general guide for ease of reading, type should not be
much smaller than 10pt, or perhaps 9pt at a pinch if well line-spaced. A
line of 45 characters of 10pt Times, for example, gives a very readable
70mm column width.
The eyes have it
Sadly, we do not all have the eyesight of youth, and for some, reading can
be hard work. It is therefore crucial that the printed word can be read
easily by the elderly as well as by the young. David Coates of the com -
pany ‘to the point’, the CIPR’s design consultants, says that the easiest
print to read has good contrast against the background, and ideally that
type should not be smaller than 11pt. ‘An unfussy, plain typeface is pre -
ferable to an ornate one and should be printed black on a matt, off-white
paper since shiny stock causes reflections and making reading difficult.
And never allow line after line of capitals: they are almost unreadable.’
It is obvious that the bigger the type, the better the readability. But there
are limits: if it is too big, say much above 12pt as recommended by the DTI
in its booklet Read me, the print begins to look like a child’s big-print word
book. The Royal Institute for the Blind advises that a minimum of 12pt
should be used ‘at all times’.
Doyen print journalist Pincus Jaspert says he is appalled by ‘computer
obsessed typographic dilettantes’ who print green on blue or the reverse,
even harder to read. ‘A single blotch of colour designed to catch the eye
instead confuses and irritates the reader.’
There is no single, clear-cut answer to what constitutes good legibility.
So much depends on typeface, the size chosen, the column or page width
and line spacing. It is the job of the designer to specify what is most
appropriate for a given audience and print medium: magazine, book,
leaflet or poster. It is the designer who is skilled in typographic principles
and knows what the printer can do who knows best.
