Have a look at the docs for Joomla pagination:

<a href="http://docs.joomla.org/Using_JPagination_in_your_component" rel="nofollow">http://docs.joomla.org/Using_JPagination_in_your_component</a>

You will need to find a vaiable that looks like:

<pre><code>$limit = $mainframe-&gt;getUserStateFromRequest('global.list.limit', 'limit', $mainframe-&gt;getCfg('list_limit'), 'int');
</code></pre>

It could be called $lim, $limit or anything else that the developer thinks is appropriate. It is usually found in the model, but it can be in the view. You need to change this variable to something like:

<pre><code>$limit = 20;
</code></pre>

Where 20 is the value for the limit you would like to set.

For J2.5 :

You can change the value form configuration.php directly:

public $list_limit = '20'; TO public $list_limit = '4'; for example.

-> But the problem is that when you will save any parametre on the backend, you will lose your config, so you need to change it angain and againt. (so it is not the best solution)

The best solution is to go to :

/administrator/components/com_config/models/forms/application.xml

Search for the field name="list_limit"

you will find the default configuration of joomla! on line 661 : 

<pre><code>&lt;field
 name="list_limit"
 type="list"
 default="20"
 label="COM_CONFIG_FIELD_DEFAULT_LIST_LIMIT_LABEL"
 description="COM_CONFIG_FIELD_DEFAULT_LIST_LIMIT_DESC"
 filter="integer"&gt;
 &lt;option
 value="5"&gt;J5&lt;/option&gt;
 &lt;option
 value="10"&gt;J10&lt;/option&gt;
 &lt;option
 value="15"&gt;J15&lt;/option&gt;
 &lt;option
 value="20"&gt;J20&lt;/option&gt;
 &lt;option
 value="25"&gt;J25&lt;/option&gt;
 &lt;option
 value="30"&gt;J30&lt;/option&gt;
 &lt;option
 value="50"&gt;J50&lt;/option&gt;
 &lt;option
 value="100"&gt;J100&lt;/option&gt;
 &lt;/field&gt;
</code></pre>

ADD an option like :

<pre><code>&lt;option value="3"&gt;J3&lt;/option&gt;
</code></pre>

it become :

<pre><code>&lt;field
 name="list_limit"
 type="list"
 default="20"
 label="COM_CONFIG_FIELD_DEFAULT_LIST_LIMIT_LABEL"
 description="COM_CONFIG_FIELD_DEFAULT_LIST_LIMIT_DESC"
 filter="integer"&gt;
 &lt;option
 value="3"&gt;J3&lt;/option&gt;
 &lt;option
 value="5"&gt;J5&lt;/option&gt;
 &lt;option
 value="10"&gt;J10&lt;/option&gt;
 &lt;option
 value="15"&gt;J15&lt;/option&gt;
 &lt;option
 value="20"&gt;J20&lt;/option&gt;
 &lt;option
 value="25"&gt;J25&lt;/option&gt;
 &lt;option
 value="30"&gt;J30&lt;/option&gt;
 &lt;option
 value="50"&gt;J50&lt;/option&gt;
 &lt;option
 value="100"&gt;J100&lt;/option&gt;
 &lt;/field&gt;

This complements seavers answer, which in my opinion is the correct answer. 

I will code an example of how I limited the number of pages that I wanted displayed in the search's results page:

From a template file root/templates/mytemplate/html/com_search/search/default.php

<pre><code>// number of max pages you want in pagination
$mylimit = 3; 

// to prevent showing pages with no resutls
$limit = min($mylimit, $this-&gt;pagination-&gt;pagesTotal);

// set the limit
$this-&gt;pagination-&gt;pagesStop = $limit;
</code></pre>

blocks|key|1933565|text|在我们的几个组件中，我们创建了一个分页扩展来覆盖默认选项，这些选项是硬编码的，不能以其他方式覆盖。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1933566|class+myCompPagination+extends+JPagination+{

++public+function+getLimitBox()+{

In several of our components we have created a pagination extension to override the default options, which are hard coded and cannot be overwritten otherwise.

<pre><code>class myCompPagination extends JPagination {

 public function getLimitBox() {
 .. Your Custom Renderer ..
 }

}
</code></pre>

The base class is found under /libraries/cms/pagination in Joomla 2.5 and higher.

Include your custom class and use it just like you would otherwise.
$pagination = new wbCompPagination( ... );

Pay attentions, to the file permission after some joomla update could change and the modification couldn't be applied to the version!

blocks|key|1939586|text|此解决方案不需要更改核心或模板文件。如果您可以控制组件代码，则可以直接在模型中使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1939587|protected+function+populateState($ordering+=+null,+$direction+=+null)
{
//+Initialise+variables.
$app+=+JFactory::getApplication();

//+List+state+information
$limit+=+$app->getUserStateFromRequest('global.list.limit',+'limit',+$app->get('list_limit'));|code-block|syntax|javascript|1939588|更改行：|1939589|$limit+=+$app->getUserStateFromRequest('global.list.limit',+'limit',+$app->get('list_limit'));|1939590|到这个|1939591|$limit+=+50;|1939592|或者你想要的任何数字。|1939593|如果您尝试将视图中JPagination对象的分页属性设置为其他属性，如@IberoMedia的回答中所建议的，那么JPagination的属性将会更改，这是可以通过echo+var_dump($this->pagination);验证的，但是在从数据库中拉出记录之前，不会对限制进行更改。因此，数据库仍将提供有限列表。这就是为什么在查询数据库之前，您必须破解模型本身，并缩短对模型中应用的全局列表限制的调用。|offset|length|style|CODE|1939594|可能有一种更周到的方法来做这件事。有没有人知道在呈现页面时和查询数据库表之前动态更改全局值的方法？我认为这样的东西会更安全、更可重用、更通用。|1939595|entityMap^0|0|0|0|0|0|0|0|9|B|1M|B|2B|X|0|0^^$0|@$1|2|3|4|5|6|7|10|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|11|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|12|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|14|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|15|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|16|8|@]|9|@]|A|$]]|$1|Q|3|R|5|6|7|17|8|@$S|18|T|19|U|V]|$S|1A|T|1B|U|V]|$S|1C|T|1D|U|V]]|9|@]|A|$]]|$1|W|3|X|5|6|7|1E|8|@]|9|@]|A|$]]|$1|Y|3|-4|5|6|7|1F|8|@]|9|@]|A|$]]]|Z|$]]

This solution does not require changing the core or template files. If you have control over the component code, then use the following code directly in your model:

<pre><code>protected function populateState($ordering = null, $direction = null)
{
// Initialise variables.
$app = JFactory::getApplication();

// List state information
$limit = $app-&gt;getUserStateFromRequest('global.list.limit', 'limit', $app-&gt;get('list_limit'));
</code></pre>

Change the line:

<pre><code>$limit = $app-&gt;getUserStateFromRequest('global.list.limit', 'limit', $app-&gt;get('list_limit'));
</code></pre>

to this

<pre><code>$limit = 50;
</code></pre>

or whatever number you want.

If you try to set the pagination property of the <code>JPagination</code> object in the view to something else, as was suggested in the answer from @IberoMedia, then the <code>JPagination</code>'s properties will be changed, as verifiable through <code>echo var_dump($this-&gt;pagination);</code>, but the changes in limits will not have been made prior to the records being pulled from the database. Therefore, the database will still provide the limited list. That's why you have to hack the model itself and short-circuit the call to the global list limit for the app in the model before the database is queried.

There is probably a more thoughtful way to do this. Does anyone know a way to change the global value on the fly when the page is rendered and before the database table is queried? I should think that such a thing would be safer, reusable, and more versatile.

I have a third party component which uses joomla's pagination system. How can I change the values of default items per page and limit box values for the front-end only, without changing anything in the back-end?
