Munshi Naan makes five basic shapes of the bread. The 'Char koni naan' being the most popular. I'm not entirely sure about why this shape is more popular than the others. I'm told by the local populace of Old City that as it's easy to tear this naan shape into four pieces and share at a table. The other shapes of the Hyderabadi Naan are a completely round shape, the oblong or the classic naan shape that we see elsewhere, the star shape, and the pan or heart shape.
