The ratio of width of the flag to its length is two to three. In the centre of the white band is a navy blue wheel which represents the chakra. Its design is that of the wheel which appears on the abacus of the Sarnath Lion Capital of Ashoka. The chakra intends to show that there is life in movement and death in stagnation. Its diameter approximates to the width of the white band and it has 24 spokes. The design of the national flag was adopted by the Constituent Assembly of India on 22 July 1947.
