Kerning panel»

The Kerning panel Window > Panels > Kerning includes the list of kerning pairs defined in the current font. If the Kerning panel is empty this means the font doesn’t yet contain kerning. Besides the list of pairs the panel includes a Preview area and a Status bar.

As soon as you start kerning your glyphs in Kerning mode, which can be activated using the Kerning tool, you will see kerning pairs appear in the list. If you click on the pair in the list you can see the pair preview below. If classes are kerned the preview will show all members of classes. Double-clicking on the pair puts it into the Glyph Window. Double-clicking on the kerning value allows to edit it directly in the table.

Pressing Enter when one pair is selected allows to edit its kerning value. Pressing Enter when several pairs are selected brings these pairs into the Glyph window.

You can easily find the particular pair using the Filter. Type the first letter of the glyph name in this field and only pairs with this glyph will be shown in the list. The number of shown/total kerning pairs can be read on the Status bar:

Multiple selections are possible in the Kerning panel. Use Shift and Cmd keys to select several pairs in the list.

To delete the selected pair(s), click on the button.

To manually adjust kerning for the selected pair(s), use the left and right ++Arrow++ keys. ++Shift+Arrow++ will change the kerning values by 10 units, ++Cmd+Arrow++ will change them by 100.

Use the local kerning menu button to perform the most common operations:

  • Reset – to remove all kerning from the font
  • Compress - to build class based kerning using kerning classes defined in the Classes panel
  • Expand - to build the plain kerning list (glyph to glyph kerning) from the class based kerning

  • Adjust - to change kerning algorithmically

  • Filter - to remove kerning pairs with small values, or pairs of glyphs from different scripts, etc.

For general information on regular and class kerning, see Kerning; for specific information on how class kerning is handled during font generation, see Using Kerning Classes; and for details on how to do regular and class kerning, see Editing Kerning.


The Adjust command in the local panel’s local menu brings the dialog box allowing you to automatically change kerning for selected or all kerning pairs:

You have three options here:
* you can adjust positive kerning values by several units or percents
* you can adjust negative kerning values by several units or percents
* you can round kerning values by the selected number of units

To apply changes to all pairs in the font, select the corresponding option and click OK.


The Filter command in the local panel’s local menu brings the dialog box allowing you to remove kerning pairs by some parameter:

You have the following options here:
* you can remove pairs with small values. For example, enter 10 to remove pairs with values from -9 to 9;
* you can remove pairs containing glyphs from different scripts;
* you can completely remove kerning for particular selected script(s).

For any case you can see the number of pairs which will be deleted.
