An apparatus for generating a character pattern includes a first memory for storing reference character font data as a coordinate point array, a second memory for storing parameter data in correspondence with at least character size data, and a generator for generating size data of a target character on the basis of the parameter data. Font data corresponding to an input character code is read out from the first memory and is developed into pattern data of a size corresponding to character size data converted by the generator. A method of generating a character pattern for the above apparatus is also disclosed.
