+# string-width [![Build Status](https://travis-ci.org/sindresorhus/string-width.svg?branch=master)](https://travis-ci.org/sindresorhus/string-width)
+
+> Get the visual width of 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 measure the actual width of command-line output.
+
+
+## Install
+
+```
+$ npm install --save string-width
+```
+
+
+## Usage
+
+```js
+const stringWidth = require('string-width');
+
+stringWidth('古');
+//=> 2
+
+stringWidth('\u001b[1m古\u001b[22m');
+//=> 2
+
+stringWidth('a');
+//=> 1
+```
