Now Official: Facebook Page Tabs To Change On August 23rd

Facebook has now set a deadline of August 23 for the new tab width limit of 520 pixels to kick in. This follows our report earlier this week that the change, first announced 10 months ago, would take effect “in the coming weeks”. The current limit is 760 pixels and many page administrators have not revised tab sizes, despite the change being mooted since October last year.

To help page administrators with the transition, Facebook is to provide the ability to preview custom tabs in the new 520-pixel width next week so any necessary changes to layouts can take place before the limits become mandatory.
