How a Cricket Ball Is Made: Manufacturing, Materials and Match Use
A cricket ball is one of sport's most precisely manufactured objects — four layers of materials around a cork core, hand-stitched with six rows of seam. This is how it is made and why it matters.
A cricket ball is among the most precisely crafted pieces of sports equipment in the world — its construction, weight, dimensions and surface properties are tightly regulated and profoundly affect how the game is played. The cricket ball's seam, lacquer, leather quality and manufacturing origin determine swing properties, durability and how the ball behaves at different stages of a match. Understanding how a cricket ball is made explains why cricket's most complex bowling techniques — swing, reverse swing and seam movement — work the way they do.
Construction and Materials
A standard cricket ball consists of a cork and rubber core, bound with twine, covered with four quarters of tanned leather that are hand-stitched together. The seam — the raised stitching that runs around the equator of the ball — consists of six rows of stitches and is the most functionally important part of the ball's construction for bowlers. The seam allows bowlers to grip the ball and place it precisely at impact; on a dry pitch, the seam grips the surface and changes the ball's direction. The lacquer applied to the leather surface gives the ball its initial hardness and shine.
The most prestigious cricket ball manufacturers are Dukes (England), Kookaburra (Australia and most international cricket) and SG (India). Each manufacturer produces balls with slightly different seam height, lacquer type and leather quality. Dukes balls retain their shine and seam for longer in English conditions — contributing to more sustained swing in Test cricket in England. Kookaburra balls lose their shine more quickly and produce less swing at later stages, favouring reverse swing and spin in the second half of an innings.
The Ball's Behaviour Through an Innings
A new cricket ball swings because the aerodynamic differential between the shiny lacquered side and the rough seam side creates pressure differences that deflect the ball's path in the air. As the ball ages — after approximately 40-60 overs of use — conventional swing diminishes because both sides of the ball have roughened equally. Reverse swing can then be generated by deliberately maintaining one side's surface (by polishing it) while the other side roughens through normal play. The ball's weight (155.9-163 grams), diameter (8.81-9 inches circumference) and bounce properties are regulated to ensure consistent conditions across all international cricket.
Frequently asked questions
Why is the pink ball used in day-night Tests?
The pink ball is used in day-night Tests because it is more visible than the red ball under artificial floodlights, and more visible than the white ball against coloured clothing worn in traditional day-night cricket. The pink ball's lacquer formulation and leather treatment differ slightly from the red ball, resulting in different swing and seam behaviour — the pink ball generally swings more in the evening conditions and under lights.
Are all cricket balls the same weight?
No. Men's cricket uses a ball weighing between 155.9 grams (5.5 oz) and 163 grams (5.75 oz). Women's cricket uses a slightly lighter ball: between 140 grams (4.94 oz) and 151 grams (5.31 oz). Junior cricket uses an even lighter ball appropriate to the age group. The weight regulation ensures consistent batting and bowling conditions across all international cricket.
How many balls are used in a Test match?
In a five-day Test match, both teams take at least two new balls per innings (one at the start and the 80-over new ball if required). A match with four innings and extended play may use six to eight balls in total, though some balls are replaced before 80 overs if they become damaged. Each ball is numbered and logged by the umpires.
