Problem: Vertical labels are displayed upside-down


Vertical Chinese, Japanese or Korean (CJK) labels display upside-down.


An inverted label tolerance to control label direction was introduced in ArcGIS 9.0 for both the standard ArcMap and Maplex label engines to accommodate different regional preferences. Vertical CJK labels display upside-down at 90 and 270 degrees with the default tolerance setting of 2 degrees.

Solution or Workaround

Change the tolerance to -2 degrees. Modify the tolerance setting for each existing map document.

Default value for new map documents can be changed by modifying a registry key.

  1. From the Labeling toolbar, click Labeling and select Options. In "Labeling Options" dialog, choose "General" tab, find "Orientation of Vertical Labels." Change the angle to -2.
  2. On the Labeling Options dialog box, select the General tab, change the Orientation of Vertical Labels to -2.
