Letter spacing is the white space built in on either side of a letter, between its drawing and the edges of its set width. In typesetting, the term also refers, by extension, to the overall spacing between the letters of a text, which can be tightened or loosened.
Where to see it
Letter spacing can be seen in the space that separates two letters of the same word, for example between the “n” and the “o” in “no”. It is most noticeable when it has been adjusted: tightened on a large headline to give it density, or opened up on text set in capitals to let it breathe.
Why this detail matters
Letter spacing sets the density of a text and contributes directly to reading comfort:
- Even letter spacing gives the text a uniform typographic color, with no dark patches or holes that catch the eye;
- Tightening the letter spacing of a headline makes it more compact and punchy, while opening it up on capitals makes them more legible and elegant;
- At small point sizes, slightly more open letter spacing helps the letters stay distinct, on paper as on screen.
