+# widest-line
+
+> Get the visual width of the widest line in a string - the number of columns required to display it
+
+Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
+
+Useful to be able to know the maximum width a string will take up in the terminal.
+
+## Install
+
+```sh
+npm install widest-line
+```
+
+## Usage
+
+```js
+import widestLine from 'widest-line';
+
+widestLine('古\n\u001B[1m@\u001B[22m');
+//=> 2
+```
