<P> By law, the flag is to be made of khadi, a special type of hand - spun cloth or silk, made popular by Mahatma Gandhi . The manufacturing process and specifications for the flag are laid out by the Bureau of Indian Standards . The right to manufacture the flag is held by the Khadi Development and Village Industries Commission, who allocates it to regional groups . As of 2009, the Karnataka Khadi Gramodyoga Samyukta Sangha has been the sole manufacturer of the flag . </P> <P> Usage of the flag is governed by the Flag Code of India and other laws relating to the national emblems . The original code prohibited use of the flag by private citizens except on national days such as the Independence day and the Republic Day . In 2002, on hearing an appeal from a private citizen, Naveen Jindal, the Supreme Court of India directed the Government of India to amend the code to allow flag usage by private citizens . Subsequently, the Union Cabinet of India amended the code to allow limited usage . The code was amended once more in 2005 to allow some additional use including adaptations on certain forms of clothing . The flag code also governs the protocol of flying the flag and its use in conjunction with other national and non-national flags . </P> <Table> Sizes of the National Flag <Tr> <Th> Flag size </Th> <Th> Length and width (mm) </Th> <Th> Size of Ashoka Chakra (mm) </Th> </Tr> <Tr> <Td> </Td> <Td> 6300 × 4200 </Td> <Td> 1295 </Td> </Tr> <Tr> <Td> </Td> <Td> 3600 × 2400 </Td> <Td> 740 </Td> </Tr> <Tr> <Td> </Td> <Td> 2700 × 1800 </Td> <Td> 555 </Td> </Tr> <Tr> <Td> </Td> <Td> 1800 × 1200 </Td> <Td> 370 </Td> </Tr> <Tr> <Td> 5 </Td> <Td> 1350 × 900 </Td> <Td> 280 </Td> </Tr> <Tr> <Td> 6 </Td> <Td> 900 × 600 </Td> <Td> 185 </Td> </Tr> <Tr> <Td> 7 </Td> <Td> 450 × 300 </Td> <Td> 90 </Td> </Tr> <Tr> <Td> 8 </Td> <Td> 225 × 150 </Td> <Td> 40 </Td> </Tr> <Tr> <Td> 9 </Td> <Td> 150 × 100 </Td> <Td> 25 </Td> </Tr> </Table> <Tr> <Th> Flag size </Th> <Th> Length and width (mm) </Th> <Th> Size of Ashoka Chakra (mm) </Th> </Tr>
