Latex Bracket

For our purposes, “brackets” refers to (parentheses), [square brackets], {curly brackets}, and ⟨angle brackets⟩, as well as |vertical bars or pipes| and ||double pipes||.

Use the \left and \right commands to create brackets that will resize themselves to match what they surround.

See the following table to learn how to write all the different kinds of brackets.

Brackets in LaTeX

Bracket	LaTeX Markup	Rendered
(Parentheses)	(a-b)	$(a-b)$
[Square brackets]	[a-b]	$[a-b]$
{Curly brackets}	\{a-b\}	$\{a-b\}$
⟨Angle brackets⟩	\langle a-b \rangle	$⟨a-b⟩$
|Vertical bars or pipes|	|a-b|	$|a-b|$
||Double pipes||	\|a-b\|	$\parallel a-b\parallel$

NOTES: For curly brackets and double pipes add backslash to escape each character.

Dynamic Brackets in LaTeX

Bracket	LaTeX Markup	Rendered
(Parentheses)	\left(\dfrac{a}{b}\right)	$\left(\frac{a}{b}\right)$
[Square brackets]	\left[\dfrac{a}{b}\right]	$\left[\frac{a}{b}\right]$
{Curly brackets}	\left\{\dfrac{a}{b}\right\}	$\left\{\frac{a}{b}\right\}$
⟨Angle brackets⟩	\left\langle\dfrac{a}{b}\right\rangle	$⟨\frac{a}{b}⟩$
|Vertical bars or pipes|	\left|\dfrac{a}{b}\right|	$\left|\frac{a}{b}\right|$
||Double pipes||	\left\|\dfrac{a}{b}\right\|	$\Vert \frac{a}{b}\Vert$
