Delimiters in LaTeX

11 commands, each with the package it needs

Symbol reference, latexci

Abstract

Brackets that grow with their content through \left and \right, angle brackets, floors, ceilings, absolute values and norms. Table 1 lists every symbol of the category with its rendered glyph, the command to type and the package to load; each name links to a page with a worked example.

1The symbols

Glyph	Command	Package	Page
$\left( \right)$	`\left( \right)`	none	Big parentheses
$\left[ \right]$	`\left[ \right]`	none	Left Right Brackets
$\left\{ \right\}$	`\left\{ \right\}`	none	Big braces
$\langle \rangle$	`\langle \rangle`	none	Angle Brackets
$\lfloor \rfloor$	`\lfloor \rfloor`	none	Floor Brackets
$\lceil \rceil$	`\lceil \rceil`	none	Ceiling Brackets
$\\| x \\|$	`\\| x \\|`	none	Norm
$\| x \|$	`\| x \|`	none	Abs Absolute Value
$\lvert x \rvert$	`\lvert x \rvert`	`amsmath`	Lvert Rvert
$\lVert x \rVert$	`\lVert x \rVert`	`amsmath`	Norm bars
$\left\| \right\|$	`\left\| \right\|`	none	Left Right Vert

Table 1. Delimiters in LaTeX: glyph, command, package (none means built into LaTeX) and the page for each symbol. Commands go inside math mode unless the page says otherwise.

2Other categories

The same table exists for every family of symbols. To find one by name or by pasting the character, use the symbol search.
