Full Stop - Spacing After A Full Stop

Spacing After A Full Stop

There have been a number of conventions relating to the spacing after a full stop. Some examples are listed below:

• One word space (French Spacing). This is the current convention in countries that use the ISO basic Latin alphabet for published and final written work, as well as digital media.
• Two word spaces (English Spacing). The two-space convention stems from the use of the monospaced font on typewriters—the intent was to provide a clear break between sentences. This spacing method has been replaced by the single space convention in published print and digital media today.
• One widened space (such as an em space). This spacing was seen in historical typesetting practices (until the early twentieth century). It has also been used in other mechanical typesetting systems such as the Linotype machine and the TeX system. Modern computer-based digital fonts can adjust the spacing after terminal punctuation as well, creating space slightly wider than a standard word space.
