Four-Per-Em Space measures exactly one quarter of an em. Known historically as the mid space, it is very close to the width of a typical regular space - but unlike a regular space, its width is guaranteed.
Click the button above to copy Four-Per-Em Space, then paste it wherever you need it. Nothing will appear on your clipboard preview - that is expected, because the character is blank.

U+2005 FOUR-PER-EM SPACE is a quarter of an em, so four of them fill the width of one EM Space. In 16px text it renders 4px wide. Most fonts draw their regular space at roughly this width, which makes the Four-Per-Em Space a useful drop-in when you want normal-looking word spacing that cannot collapse or stretch.
That property is the main reason to choose it. Substitute it for a regular space and the text looks unchanged, but the spacing survives HTML collapsing, resists justification stretching, and stays consistent across fonts.
The same character can be preserved in one place and silently removed in another. Here is what actually happens to Four-Per-Em Space in the three contexts that matter most.
Does not collapse. Useful when you need several spaces in a row to actually render.
Usually survives trimming, as it is not ASCII whitespace.
Generally preserved and looks like an ordinary space, which makes it a reasonable way to add spacing that platforms will not strip.
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.
Spacing that should look like a normal space but behave predictably - fixed width, no collapsing, no stretching.
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 Four-Per-Em 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 Four-Per-Em Space is not right for your use case, one of these probably is.
| Character | Unicode | Width |
|---|---|---|
| Six-Per-Em Space | U+2006 | Exactly 1/6 em |
| Figure Space | U+2007 | Exactly the width of a digit in the current font |
| Punctuation Space | U+2008 | Exactly the width of a period in the current font |
| Thin Space | U+2009 | About 1/5 em, though the exact width is left to the font |
| Hair Space | U+200A | The narrowest visible space - typically about 1/10 em or less |
| 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 |

Exactly one quarter of an em - 4px in 16px text. Four of them equal one EM Space.
Visually they are usually very close, since most fonts draw the regular space at about a quarter em. The difference is that the Four-Per-Em Space has a guaranteed width, does not collapse in HTML and is not stretched by justification.
It is the traditional typesetting name for this character, describing its position midway between the thick and thin spaces in a compositor's case.
