This invention provides a size measuring device, relating to the field of size detection technology. In this invention, a first laser probe measures a first vertical distance between itself and the side of the target object extending along a first horizontal direction; a second laser probe measures a second vertical distance between itself and the side of the target object extending along a second horizontal direction; and a third laser probe measures a third vertical distance between itself and the upper surface of the target object. A calculation unit is connected to the first, second, and third laser probes and receives measurement data from them to calculate the length, width, and thickness of the target object. This technical solution, through the cooperation of the laser probes and the calculation unit, measures the target object. Compared with traditional manual measurement, this device improves the accuracy of size measurement and reduces measurement errors.
