FAQ
What is letter-spacing used for?
Adjusting the space between characters (tracking) to improve readability, create emphasis in headlines, or achieve a specific typographic style like all-caps labels with wide spacing.
What is a typical letter-spacing range?
Small negative values (like -0.02em) tighten large display text, while positive values (0.05em to 0.2em) are common for uppercase labels and badges. Very wide spacing (0.3em+) is used for stylistic emphasis.
Does font weight affect how letter-spacing looks?
Yes - bolder weights have wider natural character shapes, so the same letter-spacing value can look tighter or looser depending on the weight and size you choose.
Can I copy the CSS directly into my project?
Yes - the generated letter-spacing, font-size, and font-weight declarations are ready to paste into your stylesheet.
