What Is the Six-Per-Em Space (U+2006)?
The Six-Per-Em Space belongs to Unicode’s family of fractional em spaces, each pegged to a fixed slice of the em unit so spacing stays proportional when the font size changes. At one-sixth em, it is a true micro-space: visible as a whisper of air between characters, never as a full gap.
It is particularly valuable for precise spacing control in refined layouts — optical adjustments between glyphs, delicate separation of punctuation, and tight UI text where even a quarter-em space would feel heavy. Many designers overlook it simply because it is so narrow, yet it is exactly that narrowness that makes it irreplaceable.
Where to Use the Six-Per-Em Space
| Use Case | Description |
|---|---|
| Hairline adjustments | Applies the finest reliable fixed spacing in the em-fraction family. |
| Glyph pairing | Adds optical breathing room between specific character pairs. |
| Punctuation refinement | Separates delicate marks from text with a whisper of space. |
| Tight UI text | Spaces compact labels and badges where wider spaces feel clumsy. |
| Proportional scaling | Keeps its one-sixth-em ratio automatically as font sizes change. |
Frequently Asked Questions
Exactly one-sixth of an em. In an 18px font that is about 3px of fixed space.
When a quarter-em gap looks too wide: hairline optical adjustments, delicate punctuation spacing, and very tight layouts.
Barely — it renders as a very thin gap. It is meant for fine typography, not for creating obvious blank areas.
Yes. Insert in HTML or \u2006 in CSS and JavaScript strings; it keeps its fixed width everywhere.
It is a space character, so a line may break after it. If the gap must glue words together instead, use the no-break space (U+00A0) or add a word joiner (U+2060).
