Provided are a projection type display device, a projection control method, and a non-transitory recording medium readable by a computer for recording a projection control program capable of smoothly changing shapes of projection ranges of image light. A projection type display device 1 includes: projection units 11 and 12 that project image light to a projection surface 4; a drive mechanism 13 for controlling a position, on the projection surface, of a projection range of the image light projected by the projection unit 12; and a controller 60 that controls the drive mechanism 13 and changes a length, in one direction, of a range obtained by combining projection ranges of the image light projected by the respective projection units 11 and 12 and a length, in a direction orthogonal to the one direction, of the range, respectively.
