Note to Agencies and Page Managers: Tab Widths Are Changing After All

Shortly after Facebook announced its “Platform Roadmap” a few weeks ago, we detailed 5 Things All Page and Brand Managers Should Know about the recent announcements. Please read that story for our full analysis. But one item, in particular, appeared to be unclear at the time: while we originally understood Facebook’s decision to change the width of application tabs as applying to both user profiles and Pages, Facebook told us then that “Pages will not be changing at this time.”

However, that has since apparently changed. Now, Facebook’s developer documentation says that tab widths for apps on “profiles and Pages” will be changing from 760 pixels wide to 520 pixels wide in “late 2009/early 2010.” We reached out to Facebook for confirmation, and they said that the tab width on Pages will indeed be changing as well.

This is a pretty important change for all agencies and Page managers to be aware of, because this means that all Pages that have created custom tabs (either application tabs or tabs designed around special promotions) will need to be updated to fit the new width. If not, they might look broken or poorly designed.

Facebook hasn’t given a specific date for when the new widths will be rolling out to Pages, but since we’re already in “late 2009” it could be coming very soon. We’ll let you know as soon as we have more information on the rollout schedule. For now, agencies and page managers should prepare to make the transition even though we don’t know exactly when it will happen.
