Kerning Kerning Kerning is the distance between letters.
Some letters take up more space than others, although the same space is allocated to all.
When the space between the letters is adjusted, then we say we have applied kerning. Kerning has been applied to the second sentence. The first sentence has no kerning. The e's appear to be spaced out a bit. In the second sentence, the e's have been kerned, so they are closer to the previous letter.
