An initial at the beginning of a chapter or other text requires nicety of spacing and justification. In modern practice the use of initials is often overdone, being used in many cases where they might better be omitted. Before the invention of typography, and since, the initial letter has been considered the feature of a page that could be used for decorative purposes. Early manuscripts show many elaborate, beautifully colored initials done by artists and illuminators. It was the custom of early printers to leave blank spaces in their printed pages for initials to be drawn in later. In some cases a small letter was printed in the middle of a large space as a guide to the artist. These small letters would be covered by the larger letter, but sometimes they were left as printed and the decoration drawn around them to fill the space. Later the ornamental initials were cut on wood or cast in metal and printed with the text.

As an initial is usually a prominent spot on a page its selection should be a matter of care. A plain letter of a style of face similar to the text is always a safe choice; an old-style letter for a text set in oldstyle roman, or a modern-cut Bodoni for Bodoni text. If the text is in italic an italic initial is more suitable than an upright letter. Extremely bold initials are not suitable for small types or light-faced text matter.

The size of an initial should be considered in relation to the size of the page and the size of the type used. In small pages of type of 10-point or smaller, a two-line letter will often be large enough; while a large page will require a large initial. If the initial is an ornamental letter it should be of a similar style of ornament to a head-piece or other decoration that may be on the page. Two different styles of initials or other decorative features of a page should be avoided.

In setting an initial into the beginning of a paragraph the letter is placed in the stick and the first line of text set after it. The letters of the first word are set in capitals usually, unless the first word is very long and the line of capitals is too prominent, when small capitals may be used. If the first word contains two or three letters only the next word is also set in capitals. The top of the initial should be even with the top of the first line of the text. If the initial has more shoulder than the body type, which is usually the case, a lead or more may be needed at the top of the first line. This should be properly lined up in the stick.

The spacing between the initial and the text depends upon the particular letter of the alphabet used, if a plain letter, or upon the decoration around the initial. The other letters of the first word are kept close to the initial, but the beginning of the second and succeeding lines are separated from it a little. In this way the initial has a closer relation to the word to which it belongs. The space at the right of the initial, between it and the text, should be apparently equal to that below it. It should not be extra wide in either place, or it will give the initial a detached appearance. To avoid this extra wide space it may be necessary to trim off some of the shoulder from the type, especially below the face. The proper size for an initial-letter should be equal to the number of text lines which it covers. This is not always practicable when miscellaneous types are selected from other fonts. If they are to be put back in their fonts after use as initials they may not be trimmed to odd sizes of body; nor should they ever be trimmed so without express permission of the foreman. For the usual work it is possible to use an initial that is a multiple of the text size with or without leads. An 18-point letter may be used for two-line initial in an 8-point text with 2-point leads; or a 24-point letter in leaded 10-point text.

The width of initials is very likely to make text lines after them of odd length rather than even picas or nonpareils. If the text is solid, this odd length of line is easily justified to the measure; but in case leads are used and even-pica leads do not fit it may be necessary to cut a few special odd-length leads to fit the lines. First, however, after the top line has been justified, put a few leads of even picas in the stick and try a short lead or two up and down beside the initial to fill in to the even-pica leads. If these extra vertical leads do not leave too much space around the initial they will do to take up the odd measure. Sometimes a thin space of a size two points larger than the text may be used.
