Spacing & metrics
Side bearings, linked metrics, auto-spacing, vertical metrics.
- Side bearings and widthThe white space on each side of a letter, which sets how text looks.
- Linked side bearingsMake a side bearing follow another glyph's, so changing n respaces every letter that shares its stem.
- Auto-spacingOptical side bearings for the whole font, measured from your hand-spaced n and o.
- Vertical metricsUnits per em, ascender, descender, x-height, cap height and line gap.
- Overshoots and alignment zonesRound letters reach a little past the lines; zones let points snap there.
