<p>PURPOSE: An apparatus and a method for correcting the dimension of a bent product are provided to correct a dimension error generated by the spring back phenomenon of a bent product by using laser as a heat source. CONSTITUTION: An apparatus and a method for correcting the dimension of a bent product includes a roll forming device, a measurement device (200), a controller (300), and a laser emitting device (400). The roll forming device bends a material along the movement direction of a material. The measurement device measures the measurement value in a contactless or contact manner. The controller calculates the amount of deformation by comparing the received measurement value with the preset design dimension of the bent product, and extracts dimension correction information from a database part. The laser emitting device emits laser to each location of the bent product and then corrects the dimension of the bent product.
