Facebook: Changes to Tab Dimensions on Pages Likely Coming in “Late July”

Last October, when Facebook laid out its Platform Roadmap for the next several months, it announced that the dimensions of custom tabs on Facebook Pages would be changing from 760 pixels wide to 520 pixels wide in “late 2009/early 2010.”

As we’ve been covering since, 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 landing tabs designed around promotions) will need to be updated to fit the new width. If not, they might look broken or poorly designed.

However, as late 2009/early 2010 has come and gone, there has been some confusion in the market about what Facebook’s timeline and intentions are, since the changes haven’t yet come to fruition as indicated. In fact, the developer wiki page on this topic still says the changes are coming in early 2010. This morning, a new round of confusion was set off when an FBML image caching bug confused some Page owners into thinking their tabs had suddenly been resized overnight.

A Facebook spokesperson tells us this morning that the changes to Page tab widths “will likely happen in late July, but we’ll give Page administrators at least two weeks notice before making this change regardless of when it happens.”

Facebook has been communicating this to its larger clients. For example, Nike, who recently started running what Facebook says is “one of the biggest Facebook ad buys ever” around the World Cup, already has content in the new narrower format on its Nike Football page.

So, just another heads up to all Page developers out there: you’ll want to create a 520-pixel width version of anything you plan on running on your or your clients’ Pages after mid-July. We’ll update you as Facebook issues more guidance.
