Hair Space is the thinnest space in Unicode that still has any width at all. It exists for the moments when two characters are touching and you need to separate them by the smallest amount a reader will not consciously see.
Click the button above to copy Hair Space, then paste it wherever you need it. Nothing will appear on your clipboard preview - that is expected, because the character is blank.
| Unicode code point | U+200A |
|---|---|
| Character name | Hair Space |
| Unicode category | Zs (Space Separator) |
| Rendered width | The narrowest visible space - typically about 1/10 em or less |
| Line breaking | Breaking - a line can wrap here |
| Collapses in HTML | No |
| Survives trim() | Usually yes |
| HTML entity | |
| JavaScript escape | '\u200A' |
| CSS escape | \200A |

U+200A HAIR SPACE is narrower than Thin Space - the name comes from the hair spaces of metal type, the slivers of brass a compositor slid between letters for the finest possible adjustment. Unicode does not fix its width; fonts typically draw it around a tenth of an em or less.
It is a precision tool rather than a general-purpose space. Typographers use it to fix letter pairs that collide, such as a quotation mark against an apostrophe, and to open up tight kerning in display type and logos where the font's own spacing is not quite right.
The same character can be preserved in one place and silently removed in another. Here is what actually happens to Hair Space in the three contexts that matter most.
Does not collapse, though at its width the effect is subtle enough to be easy to miss.
Usually survives trimming, as it is not ASCII whitespace.
Generally preserved, but effectively imperceptible - it is too narrow to serve as visible spacing in a name.
Not sure what is in a string you already have? Paste it into the invisible character detector to see every hidden character with its code point, or use remove invisible characters to strip them out.
The finest typographic adjustments, where even a Thin Space would be too much.
If what you actually need is text that looks completely empty - a blank WhatsApp message, an empty Instagram highlight name, a blank comment or a Free Fire name space - then Hangul Filler is the character to use, because it is not classified as whitespace and survives the trimming that removes Hair Space.
Different apps prefer different Unicode characters. Start with these combinations.
Best first choice: Hangul Filler (U+3164). Alternatives: Zero Width Space and No-Break Space.
Best first choice: Hangul Filler. Alternative for tighter formatting: Zero Width Space.
Start with Hangul Filler. If the game rejects it, try Space or No-Break Space.
Use No-Break Space for preventing line breaks, EN Space and EM Space for wider spacing, and Thin Space or Hair Space for finer adjustments. For code-ready values and conversion, see HTML Space Characters.
Width is the fastest way to choose between these characters. If Hair Space is not right for your use case, one of these probably is.
| Character | Unicode | Width |
|---|---|---|
| Narrow No-Break Space | U+202F | Narrow, similar to Thin Space |
| Medium Mathematical Space | U+205F | Exactly 4/18 em - two ninths of the font size |
| Hangul Filler | U+3164 | Renders blank; width varies by platform, often zero or narrow |
| Ideographic Space | U+3000 | Exactly 1 em - full-width, matching a CJK character |
| Left-To-Right Mark | U+200E | Zero - it is a formatting mark, not a space |
| Right-To-Left Mark | U+200F | Zero - it is a formatting mark, not a space |
| Space | U+0020 | Font-dependent, typically about 1/4 em |
| No-Break Space | U+00A0 | Same width as a regular space in the current font |
| Zero Width Space | U+200B | Zero - it occupies no horizontal space at all |
| EN Space | U+2002 | Exactly 1/2 em - half the current font size |

It is the narrowest space with any width at all - usually around a tenth of an em or less, though Unicode leaves the exact value to the font.
Not quite. It has a real width, just a very small one. For a character with genuinely zero width, use Zero Width Space; for one that looks blank but behaves like a letter, use Hangul Filler.
When a Thin Space creates too obvious a gap. Hair Space is for fixing colliding characters in display type, where you want separation the reader feels rather than sees.
