In-Depth Information
Once the designer has selected a typeface, they must then decide its size and weight.
The context in which the typography is used is critical in determining an appropriate
type size. As a society we associate size with importance. It is for these reasons that
designers may use scale to emphasize a component within a design.
It may be useful to think of where the design will be viewed; for example, reading,
walking or driving. This may help to scale elements. Reading letters are small enough
to be used for text and captions with print- or screen-based information design. Walk-
ing letters are of a size suitable for directional messages that guide pedestrians on
city streets or in interior public spaces. Driving letters are large enough to be seen by
drivers looking for directions or information.
When we talk about reading we are referring to topics, newspapers and other text
that is read from an average distance of 30-36cm (12-14in), often described as 'body
copy' or 'text type'. For printed matter, it is best to use text sizes that range between 8
and 12 points, as studies suggest it will be more legible and comfortable for the read-
er. Screen-based fonts need slightly larger sizes of 10 to 14 points, as different screens
cannot render type as accurately as print. Generally in print, any type above 12 point
is known as display or headline type. These are normally used for titles, headlines and
signage, or any text that may want to grab attention at large sizes.
