A raster scan character generator which forms different sized characters with dot pattern forming nets which are shared by characters employing common dot patterns. The generator includes a timing control which responds to a size code to selectively change the dot signal frequency as well as to perform a size conversion operation on the odd and even scan line signals. A character stroke or dot pattern encoder responds to a selected character to provide dot pattern or stroke identifier signals to a stroke/dot pattern generator. The dot pattern generator includes vertical, horizontal and slant dot pattern forming networks which respond to the dot pattern identifier stroke signals as well as to the scan line and dot signals to provide a signal pattern indicative of a selected character of a selected size.
