E91. Do's and Don'ts for Type
If you Do Don't
don't know what typeface to use select a well designed face eg. Baskerville, Times, Helvetica, Futura, etc. mix your typefaces, unless you know what you are doing.
are not usre about italics use them sparingly, for emphasis. use them for long amounts of copy, it slows down the reading.
don't know what size to use consider the use and length of line. just fill out the space available.
are wondering about the line length conisider the design of the typeface, size, line spacing and amount of copy to be set. set lines too short - the eye cannot flow over the text. Too long, the eye tires and you lose your reader.
are wondering about the line spacing use space. Text without can be slower to read from line to line. As column measure increases, so should space. set text too tight, the eye takes in other lines as well. Too widely spaced text, the reader may have trouble finding the next line.
want to reverse type letter space your type. use very small, fine or contrasting typefaces. Tightly letterspace or kern.
want to use all caps for sub heads, emphasis and short amounts of text. Ever use for long texts. Impairs reading and can add up to 35% to the space required.
