<p dir="auto">The control height classes listed on <a href="http://getbootstrap.com/css/#forms-control-sizes" rel="nofollow">http://getbootstrap.com/css/#forms-control-sizes</a> do not match the classes that actually exists in bootstrap.css and bootstrap.min.css.</p>
<p dir="auto"><code class="notranslate">.input-lg</code> is shown in the documentation,but <code class="notranslate">.input-large</code> is configured in the css. Likewise, <code class="notranslate">.input-sm</code> is shown in the documentation, but <code class="notranslate">.input-small</code> is configured.</p>
<p dir="auto">To increase/decrease the size of form controls, you can add the classes input-lg or input-sm (at least according to the website [http://getbootstrap.com/css/#forms] - which is the most consistent solution). In the css code, however, the classes are called input-large and input-small.</p>
