In order to measure the size and surface of the rug, it should be rolled out on the flat ground in a way that does not have any nuance and wrinkles, then the length and width of it will be measured by the cloth or metal of the centimeters and millimeters as follows: A-the length at three points of the rug is measured between the sides and the averages. It is not the root of the carpet in this measure unless they have a fundamental role or a special role in which this section is added to the length of the rug. (b) The width of the rug is measured from length to two parts and then every single section on the side and once again in the middle, resulting in a sum of five rugs to determine the width of that size measurement. The side of the slide is not a matter of size. The size of silk carpets is done in a high way.
