Caution, Facebook Page administrators: this week, Facebook is slated to start rolling out the new width – 520 pixels, compared to earlier width of 760 pixels – of Page tabs.
The change has been announced back in October 2009, but was delayed, presumably to let administrators prepare for the reduced tab width. Still, many popular Pages still use 760 pixel wide elements, which will look broken once Facebook implements the change. A good example is this tab on the official Victoria’s Secret Facebook Page.
If your Page contains elements that are over 520 pixels wide, you should reduce them to that width as soon as possible.
