Some embodiments provide a method for displaying text content on a device. The method receives a set of text content arranged in a single column. The method identifies a separable segment of the text content for display on a device. Based on properties of the text content and the device, the method determines whether the separable segment of the text content meets a set of characteristics for dividing the segment of text content into more than one column for display. When the separable segment of text content meets the set of characteristics, the method displays the segment of text content using more than one column.
