How do I write tilde in LaTeX?

A tilde symbol is a wavy line ( ~ ) that can be used as a symbol or appears on the head of an alphabet or symbol, \(\tilde{p}\). You may ask how one can write a tilde symbol in LaTeX? short answer: writing a tilde in LaTeX over a letter can be achieved easily using the command \tilde{symbol} or as a symbol within the text (or math mode) using \textasciitilde (or $\sim$), respectively.

In this post, we will present various methods to include a tilde symbol in our LaTeX document. Let start with a tilde over a letter or a symbol!

1. Tilde over letter

A tilde over a letter can be obtained using the command \tilde{letter}, here is an illustrative example:

% Simple tilde over text


These are alphabets with a tilde symbol, $\tilde{a}$, $\tilde{A}$,


compiling this code yields the following output:

\( \text{These are alphabets with a tilde symbol}, \tilde{a}, \tilde{A}, \tilde{p}. \)

However, this command does not change with respect to its content, for example \( \tilde{ab}\). The next section addresses the wide tilde symbol in LaTeX.

2. Long tilde in LaTeX

To remedy the above issue, we can use \widetilde command instead of \tilde{}. Here is an illustrative example:

% wide tilde over text


These is an expression with a wide tilde over it: $\widetilde{ab}$. 


compiling this code yields:

\( \text{These is an expression with a wide tilde over it: } \widetilde{ab} \)

3. How to type tilde as a symbol (~) in LaTeX

A tilde in LaTeX is a special symbol that when using it will force a non-breaking space between the left and right text. To create a tilde in LaTeX, we can use one of the following commands:

  • Math mode: we can use $\sim$ command
  • Text mode: we can use \textasciitilde command or \texttildelow.

\( \text{This is obtained by \sim command: } \sim \)

and here is the tilde symbol obtained by text-mode commands:
