A measurement system for measuring the size of a structure by using a portable terminal and a measurement method thereof are provided to perform the measurement more quickly and freely. A portable terminal(10) comprises a photographing unit(11), a focal distance calculating unit(12), a distance measuring unit(13) and a data transmitting unit(14). The photographing unit takes the picture of a structure to obtain a structure image. The focal distance calculating unit calculates the focal distance of the photographing unit, namely, the distance from a lens of the photographing unit to an image sensor. The distance measuring unit measures the distance from the photographing unit to the structure. The data transmitting unit transmits data obtained from the portable terminal or data stored in the terminal to a measurement server(20). The measurement server comprises an image processing unit(21), a size calculating unit(22) and a data receiving unit(23). The image processing unit extracts an edge from the structure image which the portable terminal provides, and then detects the length of the extracted edge. The size calculating unit calculates the size of the structure based on the output data of the image processing unit and the data provided from the terminal.
