karaktertér
Karaktertér (character space) is a term used in typography to describe the horizontal space allocated to a single character in a line of text. It is determined by the glyph’s advance width and by any side bearings that precede or follow the glyph within the font's metrics. In monospace fonts, every character occupies the same karaktertér; in proportional fonts, the width varies from glyph to glyph.
In font design, the karaktertér is defined within the font's metrics: the advance width is the distance
Spacing adjustments: Kerning adjusts the space between specific pairs of characters; tracking (letter-spacing) adjusts the karaktertér
Applications and implications: Karaktertér affects readability, word-wrapping, justification, and line length. Designers balance a comfortable karaktertér
