(5) Dimensioning Small Distances and Small Angles. When dimensioning a small distance or a small angle, always keep the lettering at the normal height of either 1/8 or 3/16.

Figure 72 (on the following page) shows several different ways to dimension small distances or angles and still keep the dimensions at the normal height.
