Specifying the default character spacing when spreading a label along a line

Steps:

1. Click the Label Manager button on the Labeling toolbar.
2. Check the check box next to the layer you want to label.
3. Choose a label class under the layer.
4. Click Symbol.
5. Click Edit Symbol.
6. Click the Formatted Text tab.
7. Type a value for the character spacing.

This will be the minimum character spacing when you choose to spread the characters in your labels.

8. Click OK to close all dialog boxes.

Tip:

You can also open the Placement Properties dialog box by clicking the Placement Properties button on the Labels tab of the Layer Properties dialog box for the layer you want to label.

Tip:

A value of 0 (default) is interpreted as no limit, and the label is stretched to fit the feature. A value of 100 adds a full character space (average character width of the font) between each character.
