Abstract: A method of length measurement for 2d photography comprises the following steps. A reference object and a measuring object are respectively photographed to form a reference image and a measuring image, wherein the reference object has a geometrical shape capable of being represented by an area formula saved in a computer with a predetermined size. A background image is separated from the reference image and then the reference image is scanned to obtain a total number of pixels included therein, and a first number of pixels corresponding to a unit length is obtained based on the predetermined size and the area formula. An actual length between any two points of the measuring object image clicked on a screen of the computer can be obtained based on a ratio of a second number of pixels corresponding to the two points to the first number of pixels.
