Facebook Update: new 520 pixel width We announced plans last October to remove application boxes and application info sections as well as reduce the width of application tabs to optimize for the new profile and Facebook Pages format. We will be moving forward with these changes the week of August 23, and want to help you understand what to expect. Based on feedback from developers, we have committed to the following plans to ensure a smooth transition: Boxes. We will notify users via messaging in profile boxes and in the Help Center that the "Boxes" tab, boxes on profiles and Pages, and application info sections will be going away. Application Tabs. Next week, we will give Page admins the ability to preview their custom tabs in the new 520 pixel width so they can modify their layouts as needed. All profile and Page tabs will be resized automatically beginning the week of August 23. These updates are designed to simplify navigation for users, reduce complexity for developers, and enable us to build the next generation of tools for growing your business with Facebook. We'll share more of our plans for the roadmap in the coming weeks. Fran, a Platform product marketing manager, is busy updating the roadmap.
