The longest Unicode character the test computer drew is ﷽, U+FDFD, a single Arabic ligature. 80 more follow: the widest, the tallest, the longest names and the longest spelled out. A device with no font for one shows an empty box.

How the order was made
Unicode gives a character no width or height: the font decides. So the 38,940 visible characters that Unicode 18.0 lists by name were laid out in the system fonts of one computer and each was measured. Longest and widest runs widest first and Tallest tallest first. Another font will shuffle neighbours, so the longest character on one screen may not be the longest on the next.
Long by the book
Two groups rest on Unicode's own files. Longest names counts the letters and spaces of each character name. Longest spelled out counts the characters one character stands for: ㌖ stands for the six katakana of kilometer.
The longest symbol that is plain punctuation is ⸻, the three-em dash: the widest punctuation mark drawn.
Questions and answers
What is the longest Unicode character?
On the test screen it was ﷽, U+FDFD, Arabic ligature Bismillah ar-Rahman ar-Raheem, the widest Unicode character measured: as wide as 13 letters x. The cuneiform sign 𒐫, U+1242B, came second.
What is the longest Arabic character?
﷽ again: it sits in the block Arabic Presentation Forms-A. Counted in letters, the longest Arabic character is ﷺ, U+FDFA, which Unicode maps to 18 characters, three of them spaces.
What is the tallest Unicode character?
The tallest drawn was 𒀱, U+12031, cuneiform sign an plus naga squared. Outside cuneiform the Javanese mark ꧌, pada piseleh, stood tallest. Stacked combining marks climb higher, but a stack is several characters.
What is the biggest Unicode character?
By room on the screen, ﷽. By number, the largest Unicode code point is U+10FFFF, where the codespace ends: a noncharacter that draws nothing. The highest code point with a name is U+E01EF, variation selector-256.
Which character has the longest name?
U+1FBA8 and U+1FBA9, two box drawings characters added in Unicode 13.0, share the longest: 88 characters with spaces. The test computer had no font for them. The longest emoji name is couple with heart: person, person, medium-light skin tone, medium-dark skin tone, at 80.

How this list was compiled: Compiled on 2026-10-08 from Unicode's own files, each read that day. Names, code points, categories and compatibility decompositions come from UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt); block names from Blocks.txt (https://www.unicode.org/Public/18.0.0/ucd/Blocks.txt); the Unicode version each character arrived in from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt); the glosses quoted as "the names list" from NamesList.txt (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt), all version 18.0.0. Emoji, their names and code point sequences come from emoji-test.txt, version 18.0 (https://www.unicode.org/Public/18.0.0/emoji/emoji-test.txt). The length of every character name (spaces and hyphens counted), of every emoji name and of every decomposition was counted over the whole file. Width and height are not properties of a character, so the first two groups are this site's own measurement: on 2026-10-08 every named character of UnicodeData.txt outside the control, format, space, private-use, nonspacing-mark and enclosing-mark categories (38,940 code points; the CJK, Hangul and Tangut ranges, which the file lists as ranges, are not in it) was laid out at one size in the system fonts of one computer. 25,337 drew in a real font; the rest fell back to the last-resort box and are left out. The width is the advance of the line and the height is the height of the ink. Longest and widest holds the eight widest (one sign for a run of signs that drew at the same width) and then the widest character of every other block that drew at least 1.75 ems wide; Tallest holds the six tallest and then the tallest of every other block that drew at least 1.2 ems tall. The Grantha block is left out of both because that computer drew it with a Tamil font. Another font will give other widths and may shuffle neighbours. Longest names holds 15 of the 16 characters with a name of 72 characters or more that drew (the 16th, U+1F502, is an emoji and sits in the last group); 8 more with names that long, the two record holders U+1FBA8 and U+1FBA9 among them, drew as boxes and are named in the text only. Longest spelled out holds the 19 characters with a compatibility decomposition of five characters or more that drew; three parenthesized and circled Korean words (U+321D, U+321E, U+327C) drew as boxes. That the codespace ends at U+10FFFF and that U+10FFFF is a noncharacter is from the Unicode glossary (https://www.unicode.org/glossary/, entries Codespace and Noncharacter). The Arabic word ligatures are listed as characters with their Unicode names and nothing more. Spacing combining marks are left out because they are drawn on another letter. Licence: own work: the selection, the measurements and the notes are this site's own. Character names, code points, decompositions and emoji names are Unicode data, used under the Unicode License v3 (https://www.unicode.org/license.txt).
