In this post, I will show you how to limit the collection of a Model in Magento. I will use catalog product module for this example.

First, you can use setPageSize() method for setting number of items you want to display in one page.

    Mage::getModel(‘catalog/product’)->getCollection()
       ->setPageSize(10);

The second example is to display 10 items from a 5th item

    $start = 5;
    $limit = 10;
    $collection = Mage::getModel(‘catalog/product’)->getCollection();
    $collection->getSelect()
       ->limit($limit,$start);
