In Django admin when you select related object in Django admin -- it shows you popup window. Size of this popup is hardcoded to 800x500 px and does not always match user expectations. It would be great to allow changing it at least system-wide.


  1. Provide a setting to change default popup size
  2. Use some global Javascript variable for storing popup size so we could override per page

Sample application:


class Author(models.Model):
    name = models.CharField(max_length=100)

class Book(models.Model):
    author = models.ForeignKey(Author)
    name = models.CharField(max_length=100)


class AuthorAdmin(admin.ModelAdmin):

class BookAdmin(admin.ModelAdmin):
    raw_id_fields = ('author',)

Source code:

// RelatedObjectLookups.js

    function showAdminPopup(triggeringLink, name_regexp, add_popup) {
        var name =, '');
        name = id_to_windowname(name);
        var href = triggeringLink.href;
        if (add_popup) {
            if (href.indexOf('?') === -1) {
                href += '?_popup=1';
            } else {
                href += '&_popup=1';
        var win =, name, 'height=500,width=800,resizable=yes,scrollbars=yes');
        return false;

It is the workaround I had to add via base.html (does not work well with Firefox and not smooth):

function resize_for_popup() {
    if(/[?&]_popup=1(&|$)/.test(location.href)) {
        // In Firefox you may need to set (via about:config): dom.disable_window_move_resize = false
        var reference = window.opener || screen;
        var width = parseInt(reference.outerWidth * 2 / 3);
        var height = parseInt(reference.outerHeight * 2 / 3);
        window.resizeTo(width, height);

Could you elaborate on "does not always match user expectations"? Maybe it makes sense to change the default since monitor resolution has increased over the years. I'm not sure if adding a setting for this is really needed.

comment:3 Changed 3 years ago by Artem Skoretskiy

Users expect something bigger than 800x500. It is hard to suggest a single resolution for everyone -- some users have 1280x768, others have 1920x1080 monitors.

Another alternative is to calculate popup size in runtime by JavaScript according to user screen size. We could reuse parts of my workaround (it generates 2/3 of size of source window or screen).

Maybe you could raise the idea on the DevelopersMailingList and ask for ideas.
