I just wonder why the size/width in Product Grid in the admin panel is not adjusting. I created a local copy of the grid.php from the core file. I tried editing the sizes of the column (/app/code/local/Mage/Adminhtml/Block/Catalog/Product/Grid.php) but when I try to refresh the admin page nothing happens. I cleared the cache still the same the width are the same.

Can anyone guide me how to increase the width size of every column?

In addition, is there a way I can the FROM and TO in the PRICE and QTY Column? How?

  • Have you added such column to grid collection?

If you remove 'type' => 'number' from the array then you will be able to change the width.

  • I have faced same problem, when I remove 'type', I am able adjust the width, else not. I can't find logic behind it Commented May 26, 2016 at 11:28

Try the below,

In app/code/local/Mage/Adminhtml/Block/Catalog/Product/Grid.php

Under _prepareColumns() function,

                'header'=> Mage::helper('catalog')->__('ID'),
                'width' => '50px',
                'type'  => 'number',
                'index' => 'entity_id',

By changing this 'width' => '50px',the column width can be changed

  • With the help of width you can set the width of column, you can change as per your requirements. Commented Aug 3, 2015 at 9:15
  • The way I understand it first, yes I'll just have to adjust the width of every column in _prepareColumns() but the thing is, it's not working. So I was thinking that maybe there's still a different file that needed to be edited.

For those 'width' => '{number}px', is not working as intended, if you have a hidden column, the width change will take place x column(s) earlier.

For example, if you have columns as follows, you will have to place 'width' => '25px' in the column2 in order to change the width of column3

$this->addColumn('hidden_column1', array('header' => 'hidden_column1', 'column_css_class'=>'no-display', 'header_css_class'=>'no-display'));
            'header' => 'column2',
            'width' => '25px', //here
            'header' => 'column3',
             //not here
