# text-width

A small utility for measuring the text width in browsers that support the canvas API.

# Usage

Install through `npm` and require it with `browserify`. It uses the [ctx.measureText][mt] method for acquiring the text width.

```javascript
var width = require('text-width');

var w = width('hello world', {
	family: 'Arial',
	size: 10
});
```

It supports following font options, `style`, `variant`, `weight`, `size` and `family`. Each corresponding to a similarly named [CSS property][font]. The size option can either be a number (size in pixels) or a string, e.g. `10pt`.
