Parentheses and brackets are very common in mathematical formulas. You can easily control the size and style of brackets in L a T e X , this article explains how.

Introduction

The size of the brackets can be manually set, or they can be resized dynamically in your document, as shown in the next example:

$\left \{ \begin{tabular}{ccc} 1 & 5 & 8 \\ 0 & 2 & 4 \\ 3 & 3 & -8 \end{tabular} \right \}$

Notice that to insert the brackets, the  \left  and  \right  commands are used. Even if you are using only one bracket both commands are mandatory.

Controlling types and sizes

The size of the brackets can be controlled explicitly

Manually sized brackets

$\Bigg \langle 3x+7 \Bigg \rangle$

The commands  \Bigg  and  \bigg  stablish the size of the delimiters  <  and  >  respectively. For a complete list of parentheses and sizes see the reference guide .
