The invention provides a method and device for determining selectable zones of candidate entries. According to the method and device for determining the selectable zones of the candidate entries, multiple candidate entries corresponding to input sequences to be displayed on a current screen are determined according to the input sequences input by a user, the sizes of the selectable zones of the candidate entries are obtained, the sizes of the selectable zones of the candidate entries are determined based on weights of the corresponding candidate entries, and the user can select corresponding candidate entries in the selectable zones of the corresponding candidate entries. The sizes of the selectable zones of the candidate entries to be displayed on the current screen are determined based on the weights of the corresponding candidate entries. According to one preferable embodiment, the bigger the weights of the candidate entries are, the selectable zones are larger. Therefore, the candidate entries with the bigger weights can be more easily selected by the user, the probability of wrong selection of the user, caused by small selectable zones, is reduced, and the input experience of the user can be improved.
