How Cricket Balls Are Made: Materials, Layers, and Differences
The manufacturing process of a cricket ball — from its cork core to its leather casing, the difference between red, white, and pink balls, and how the ball behaves differently in each format.
A cricket ball looks simple from the stands — a round red object. But the engineering inside it, and the manufacturing traditions around it, are central to why cricket plays the way it does. The ball's behaviour determines whether a bowler swings it, seams it, or spins it, and how it behaves over 80+ overs.
The Structure of a Cricket Ball
A regulation cricket ball consists of a cork core wrapped in string (tightly wound thread), enclosed in a two-piece leather case with a prominent raised seam. The seam is hand-stitched with 6 rows of stitching and is the most important structural feature for bowlers — it creates aerodynamic asymmetry that generates swing.
| Layer | Material | Function |
|---|---|---|
| Core | Cork and rubber composite | Weight and hardness |
| Inner windings | Worsted yarn/string | Maintains shape |
| Outer case | 4-piece or 2-piece leather | Aerodynamics, grip |
| Seam | 6-row hand stitching | Swing and seam movement |
The Three Major Manufacturers
Dukes (UK), Kookaburra (Australia), and SG (India) are the three ICC-approved manufacturers for international cricket. Each ball behaves differently due to manufacturing differences, and their dominance in different regions is why conditions feel so different worldwide.
- Dukes: Used in England and West Indies. Harder leather, pronounced seam, swings for longer in English conditions. Preferred by seam bowlers.
- Kookaburra: Used in Australia, South Africa, New Zealand, Sri Lanka, Pakistan (ODIs/T20). Seam flattens quickly, reverse swing becomes relevant after 30–40 overs.
- SG (Sanspareils Greenlands): Used in India for Tests. Medium hardness, responsive on spin-friendly Indian pitches.
Red, White, and Pink Balls
Red balls are used in Test cricket and first-class cricket. They are dyed red and have traditionally been the standard. White balls replaced red for limited-overs cricket (ODIs and T20s) because they are more visible under floodlights and against coloured clothing. However, white balls deteriorate faster than red balls.
Pink balls were introduced for Day-Night Test cricket (the first was played between Australia and New Zealand in Adelaide in November 2015). Pink is visible under floodlights while retaining the hardness of a red ball. However, pink balls behave differently from red — they swing more in the first 15 overs and have different deterioration characteristics.
Ball Condition and Tactics
Ball maintenance is a legal and tactical science. The fielding team can polish one side of the ball with sweat (legal) but not with artificial substances (illegal — ball tampering). Keeping one side shiny and allowing the other to roughen creates the asymmetry that generates conventional swing. Once the ball is old enough, the rough side can catch air differently at high speed — reverse swing.
Ball Replacement Rules
In Tests, the fielding team can take a new ball after 80 overs. They may choose not to if the old ball is reverse swinging effectively. In ODIs, the ball is replaced if it becomes too misshapen or damaged — the on-field umpires decide based on a standard template. T20 typically uses a single ball unless it becomes damaged.
Frequently asked questions
Why is a cricket ball red?
Red dye has been the traditional cricket ball colour since the 18th century — it was the most visible colour against white clothing on green grass in natural daylight. White and pink balls were developed later for different lighting conditions: white for day/night limited-overs, pink for day-night Tests.
What is the difference between Dukes and Kookaburra balls?
Dukes balls (used in England and West Indies) have a harder outer casing and a more pronounced seam that maintains conventional swing for longer. Kookaburra balls (used in Australia, South Africa, New Zealand) have a softer leather and flatter seam — the ball deteriorates faster, reducing conventional swing but encouraging reverse swing.
What is reverse swing?
Reverse swing occurs when an old cricket ball (typically 30–40+ overs old) swings in the opposite direction to what the seam position suggests. It requires a ball with one rough side and one polished side, bowled at high pace. Wasim Akram and Waqar Younis were the pioneers of deliberate reverse swing bowling.
