There is a lot of room on that field column and the box is quite small, widening this box would be good.
On product edit page? I think it is possible
On product lists page.

Width is set in the controller:
admin/controller/pages/catalog/product.php
See code:
$grid_settings['colModel'] = array(
array(
'name' => 'image',
'index' => 'image',
'align' => 'center',
'width' => 65,
'sortable' => false,
'search' => false,
),
array(
'name' => 'name',
'index' => 'name',
'align' => 'center',
'width' => 200,
),
