Facebook Widget Height and Width Settings Overwritten by Inline CSS

Jetpack itself doesn’t add that inline CSS. It’s most likely added by your theme, to make sure the widgets to break the sidebar layout.

Could you post your site URL here, so I can have a look?

If you want it to remain private, you can also contact us via this contact form:

Thanks!

Could you let me know what your widget settings are? Do the “325px” and “400px” remain when you save the widget settings, or do they changed to 185px and 130px?

Thanks!

It appears that Jetpack outputs the right values, as you can see when looking at your site’s source code:

Facebook’s JavaScript library, however, overwrites those values:
http://i.wpne.ws/ezY2

This is most likely because Facebook’s Page Plugin is built to adapt its width to the width of the widget container.
To test that theory, you could try to increase the width of that container by adding the following to your theme stylesheet or to your custom CSS editor available under Appearance > Edit CSS in your dashboard:

@media (min-width: 981px) {
	.widget_facebook_likebox {
		width: 325px;
	}
}

Let me know how it goes.
