Typeface- the design of alphabetical and numerical characters unified by consistent visual properties. Font- Character set of a given size and style including upper and lower case letters, numerals, and punctuation marks. Points and Picas are universal units of measurement used by graphic designers and printers to describe type sizes, measure the lengths of lines, line spacing, and the dimensions of a typographic area. Vertical Measurement = POINT = 1/72" of an inch. Horizontal Measurement = Pica = 1/6" of an inch. 6 Picas = 1 inch The size of type is reflected in the standard measurement, POINTS
Generally sizes from 8 point and below as in footnotes and disclaimers occupy a subordinate relationship to the rest of the type on the printed page. Text sizes or body copy run from 8 to 12 points. Headline sizes, as in chapter headings and display type, run from 14 to 42 and sometimes 72 points. Each typface is unique in its aesthetic appeal. Some work well for advertising and promotional materials, while others are more simple and restrained lending themselves more to logo and trademark design. These days it seems that anything goes in terms of size relationships, hierarchy and general readability. Digital typography has opened up a cornacopia of possible type combinations that designers can explore. Now a single designer can have as many typefaces as a CPU can hold and for the first time one can preview the merit of a design concept with the click of the mouse.
