+# unist-util-size [![Build Status][travis-badge]][travis] [![Coverage Status][codecov-badge]][codecov]
+
+Calculate the number of nodes in a [**Unist**][unist] tree.
+
+## Installation
+
+[npm][]:
+
+```bash
+npm install unist-util-size
+```
+
+## Usage
+
+```js
+var h = require('hastscript');
+var size = require('unist-util-size');
+
+var tree = h('div', [
+  h('p', ['Some ', h('strong', 'importance'), ' and ', h('em', 'emphasis'), '.']),
+  h('pre', h('code', 'bar()'))
+]);
+
+console.log(size(tree)); // 11
+console.log(size(tree.children[0])); // 7
+console.log(size(tree.children[0].children[0])); // 0
+```
+
+## API
+
+### `size(tree)`
+
+Calculate the number of nodes in [`node`][node].
+The result is excluding the given node itself.
