The most basic components of the game of cricket are a bat and a ball. While the bats have undergone a substantial transformation over the years, the balls have, more or less, remained the same.
Cricket ball manufacturing
A cricket ball is made from cork strips and a tightly wound string. It is then covered by a leather case with a slightly protruding seam. The outer layer of a ball, which is covered by the highest quality leather, is cut into four pieces. The seam of a cricket ball has a total of 6 stitches, 3 on either side. The seam is diligently rotated by 90 degrees to make sure that a cricket ball has an uniform shape to it. Each section is then put into a vice, which moulds the leather into the shape of a hemisphere.
Weight and dimensions
As far as the weight and dimensions of a cricket ball are concerned, the regulations are different for men’s cricket and women’s cricket. For men’s cricket, a cricket ball must weigh between 5.5 and 5.75 ounces and measure between 8 13/16 and 9 inches in circumference. With regard to women’s cricket, it must weigh between 4 15/16 and 5 1/16 ounces and measure between 8.3 and 8.9 inches in circumference.
Place of manufacturing
Cricket balls were traditionally made by companies, employing highly skilled craftsmen, residing in Kent, South East England. But, with increasing labor costs and an ever-growing demand, the factories in Kent were forced to look towards the sub-continent, where the labor was more in number and cheaper at the same time, thereby reducing the production cost.
Consequently, Jalandhar in India and Sialkot in Pakistan have become the two hubs of cricket ball-manufacturing, with approximately 98% of cricket balls used in club cricket currently being manufactured in the above two places. In fact, even Kookaburra, a famous Australian-based company, now has a factory in the sub-continent.
The red ball is being used in Test and first-class cricket since time immemorial. While it has remained fairly the same in weight and dimensions, the same cannot be said of the colour of the ball. White cricket balls, which are very common now, were introduced during World Series Cricket, which began in the late 1970s.
With the night matches and coloured clothing coming into the scene, the players were finding it difficult to spot the red ball during the night. The search began for a ball that would be visible against coloured clothing and at night, and the white balls provided the solution and are now the standard for all one-day games across the world.
Different cricket balls around the world
While the cricket balls used in Test cricket are all dark red in colour and round in shape, the manufacturer depends upon the location. At the Test match level, there are three basic balls used: the Kookaburra in Australia, New Zealand, West Indies, Pakistan, South Africa and Sri Lanka, the Duke in the United Kingdom and the SG in India. In the limited overs formats, though, Kookaburra balls are used across the spectrum irrespective of the location.
Each country has its own preference in regards to the choice of the cricket ball, which is why one particular cricket ball has not been standardized by the International Cricket Council. The three cricket balls widely used in Test cricket have their own merits and demerits.
Comparison between the Kookaburra, the Duke and the SG

- The Kookaburra ball is machine-made, while both the Duke and SG balls are hand-made.
- The Duke and the SG have a more pronounced seam than the Kookaburra, which makes it easier for the spinners to grip the ball.
- The Kookaburra ball swings more than the Duke and SG balls in the 1st 20-30 overs, after which it goes soft and loses its seam and stops swinging. The Duke, on the other hand, doesn’t swing in the 1st few overs because of the lacquer on the ball. Once the lacquer on the ball wears off, the Duke starts swinging, and it swings for a much longer period than the Kookaburra or the SG. The SG, although quite similar to the Duke, hardly swings.
- The Duke’s usefulness is mainly limited to the United Kingdom. This is because of its leather, which cannot last on the rougher conditions found in the sub-continent and in places like Australia.
- As far as reverse swing is concerned, the Duke is more likely to assist reverse swing as compared to the Kookaburra and the SG.
