This is my example of bad kerning. Both the first and last names are broken into “Da Vid W Ard”.
Kerning uses selection to vary space between the letters, accounting for shape and permitting letters to extend into the virtual area surrounding the letter (block). The text becomes more readable when the distance between letters are well-spaced.
Leading is the space between lines of text. The distance is measured between the baseline of one row and the baseline of the next. Leading allows readers to advance their eyes from one line to the next line when studying text.
