typometer

Article summary

scale in groups of three, six and twelve points (one quarter cicero, half a cicero and one cicero) A typometer is a ruler which is usually divided in typographic points or ciceros on one of its sides and in centimeters or millimeters on the other, which was traditionally used in the graphic arts to inspect the measures of typographic materials. The most developed typometers could also measure the type size of a particular typeface, the leading of a text, the width of paragraph rules and other features of a printed text. This way, designers could study and reproduce the layout of a document. One of the domains where the typometer was most widely used was the editorial offices of newspapers and magazines, where it was used along with other tools such as tracing paper and linen testers to define the layout of the pages of the publications, until the 1980s. Typometers were initially made of wood or metal (in later times, of transparent plastic or acetate), and were produced in diverse shapes and sizes. Some of them presented several scales that were used to measure the properties of the text. Each scale corresponded with a type size or with a leading unit, if line blocks were divided by blank spaces. However, typometers could not be used to measure certain computer-generated type sizes, that could be set in fractions of points.…
