Frequently Asked Questions

What does one character (X) represent in typography?
It represents the horizontal space taken by one character in a specified font and style, often the advance width of a glyph.

Why is the en unit important in typography?
An en is half the width of an em unit, tied to the font size, and is used for relative spacing and lengths like en dashes and en spaces.

Can this conversion vary between different fonts?
Yes, because character (X) depends on specific font metrics, conversions to en units can differ with font choice and style.

Key Terminology

Character (X)
A typographic unit that measures the space a single character occupies in a given font and style.
En
A horizontal typographic unit equal to half an em, used for relative widths and spacing based on font size.
