Parentheses and brackets are very common in mathematical formulas. You can easily control the size and style of brackets in LaTeX; 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.
