The official aspect ratio of India’s national flag is 2:3.
This proportion means the flag’s height is two units for every three units of length. The rectangle is divided into three equal horizontal bands: India saffron at the top, white in the middle, and India green at the bottom. A navy-blue Ashoka Chakra sits at the center of the white band.
The present design was adopted by India’s Constituent Assembly on 22 July 1947, shortly before independence. It developed from the earlier Swaraj flag associated with the Indian independence movement and Pingali Venkayya’s design. The spinning wheel, or charkha, was replaced by the Ashoka Chakra, a 24-spoke wheel linked to the ancient Mauryan emperor Ashoka and the idea of dharma.
The ratio is sometimes written as 3:2 when length is listed before height, which can cause confusion. India’s official flag specifications also define standard sizes, materials, colors, and construction details. The ratio applies to the national flag; some naval or government ensigns have different proportions.
