The invention discloses a character size recognition method and device, and belongs to the technical field of text image processing. The method comprises the steps of performing text line detection on a target image, obtaining text line position information of a detected text line, and obtaining an original text line image of the text line according to the text line position information; performing relative scale transformation on the original text line image to obtain a first transformed text line image; according to the height and width of an input image matched with a pre-trained character size identification model, carrying out image processing on the first transformation text line image to obtain a second transformation text line image; and taking the second transformation text line image as the input of the character size identification model. According to the character size recognition method and device disclosed by the embodiment of the invention, the problem that the character size information in the
