By “metrics”, we refer to information about a glyph’s width and
sidebearings. In FontLab you can modify this information either manually
or automatically.
To modify a glyph’s metrics you must switch the Metrics Window to the
Metrics mode. To do this, push the
button in the mode selection area:
or, select the Metrics command in the popup menu that appears if you
press the right mouse button in the editing area of the Metrics Window.
By default the Property area is empty. To make the metrics editing controls
visible, click on the left mouse button on a glyph in the editing field. The
metrics editing controls will appear and the sidebearings lines with editing
handles will appear at the sides of the glyph:
The numbers at the bottom of the glyph are the left and right sidebearing
values and the glyph’s width.
