Understanding Point Sizes

A point is a typographical term for a unit of measure. It is equivalent to 1/72 of an inch. Points are understood and used extensively by everyone in the publishing trade, particularly in design, typesetting, and printing. They are most commonly used with type specifications. Word uses point sizes to specify the height of all the fonts it uses. Thus, when you use a 12-point type, you are using one that occupies a character box approximately 12/72 (or 1/6) of an inch high from the top of the highest riser, to the bottom of the lowest descender. Likewise, 72-point type uses a character box that is about one inch tall.

In typesetting, points are also the measurement of choice when specifying line leading (as discussed in a different tip). It is not uncommon to specify type in the format 10/12, meaning 10-point type on 12-point line leading.

If you are familiar with points, you can use them as a standard measurement in Word. When entering a measurement in points, simply use the characters pt at the end of the measurement. Alternately, you can set your default measurement to points by following these steps:

1. Display the Word Options dialog box. (In Word 2007 click the Office button and then click Word Options. In Word 2010 or a later version, display the File tab of the ribbon and then click Options.)
2. Select the Advanced option at the left of the dialog box.
3. Scroll down until you can see the Display section. (See Figure 1.)

4. Use the Show Measurements in Units drop-down list to choose Points.
5. Click OK to save the change.
