To change the height of input elements, use the control sizing classes of Bootstrap:
Here's some examples of them in use:
<!DOCTYPE html>
<html lang="en">
<head>
<script type='text/javascript'
src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<link rel="stylesheet"

<script

<script type="text/javascript">
$(document).ready(function(){<!-- w w w. ja v a 2s. c o m-->
$('.myDropdownHandle').dropdown('toggle');
});
</script>
</head>
<body style='margin:30px'>
<div class="form-group has-success">
<input class="form-control input-lg" type="text" placeholder="Larger Input Field">
<input class="form-control" type="text" placeholder="Default Input Field">
<input class="form-control input-sm" type="text" placeholder="Smaller Input Field">
</div>
</body>
</html>We can control the height of input and select boxes to match the button sizes.
.input-lg, .input-sm can be used both on <input> and <select> boxes to create it's larger or smaller sizes.

</div>
<br>
<div class="row">
<div class="col-xs-6">
<input type="text" class="form-control input-sm" placeholder="Smaller input">
</div>
<div class="col-xs-6">
<select class="form-control input-sm">
<option>Smaller select</option>
</select>
</div>
</div>
</form>
</div>
</body>
</html>We can match the sizes of form controls to the Bootstrap grid column sizes. Wrap form controls such as <input>, <textarea>, and <select> in grid columns, or any custom element and apply the grid classes on it.

<select class="form-control">

</select>
</div>
</div>
</form>
</div>
</body>
</html>We can add the relative form sizing classes to the .input-group to
make it larger or smaller.
The contents within .input-group will automatically resize.
