Systems and methods are provided for generating a personalizable user interface (UI) component layout on a curved screen on a mobile electronic communication device, the curved screen having a front screen display surface and a plurality of edge screen display surfaces. In an example, the described technique entails detecting that a device user has opened an application on the mobile electronic communication device, determining whether the application opened by the user supports placement of UI components on edge screen display surfaces, and determining a coverage area on the front screen display surface and the edge screen display surfaces areas when the application supports placement of UI components on edge screen display surfaces, and estimating a user hand size based on the determined coverage area, and placing one or more UI components on an edge screen display surface to be reached by the user based on the estimated hand size.
