PURPOSE: A device and a method for measuring a size are provided to detect an accurate absolute size of a product by confirming positions of both end parts of the product and to reduce a failure rate of the processed product by partly measuring the absolute size of the product being consecutively provided before processing. CONSTITUTION: A device for measuring a size comprises a frame(100) and a detector(200). The frame is installed along a width and a longitudinal direction of a product. The detector confirms both end parts of the product by being installed in the frame and detects an absolute size of the product by confirming positions of the both end parts of the product.
