Cricket Ball Size and Weight: Full Comparison by Format

A batter facing a 90mph delivery has less than half a second to react, and every one of those milliseconds is shaped by a ball whose weight and size have barely changed since Victorian cricket administrators wrote them into law. Law 4 of the MCC Laws pins a men’s ball to 155.9-163 grams and a circumference of 22.4-22.9 cm. Women’s and junior balls are lighter and a touch smaller.

Official cricket ball specifications

Format / Level	Weight	Circumference
Men’s senior (Test, ODI, T20I)	155.9 g – 163 g	22.4 cm – 22.9 cm
Women’s senior	140 g – 151 g	21.0 cm – 22.5 cm
Under-13 / junior (approx.)	~133 g	~20.5 cm

Exact junior specifications may vary by national board.

Red, white, and pink balls: same size, different purpose

All three colours meet identical weight and size limits. What differs is how they’re made and where they get used. The red ball, used in Test and first-class cricket, swings more as the lacquer wears off and can reverse-swing once it’s roughed up past the 40 or 50-over mark. The white ball, used in ODIs and T20s, gets replaced from both ends in one-day cricket specifically because it loses its shine (and its swing) faster than red leather. The pink ball exists for one reason: visibility under floodlights in day-night Tests, and manufacturers have spent years adjusting its lacquer just to keep it seeing conditions comparable to a red ball.

Seam condition, lacquer thickness, and how much sheen a ball holds all vary between manufacturers, and that’s really where the “different feel” between balls comes from. The Laws don’t touch any of that. They only fix weight and circumference.

How cricket ball size compares to other sports

Sport	Ball weight (approx.)	Circumference (approx.)
Cricket (men’s)	156-163 g	22.4-22.9 cm
Baseball	142-149 g	23.0-23.5 cm
Tennis	56-59 g	~21.0 cm
Football (soccer)	410-450 g	68-70 cm

A cricket ball sits between a tennis ball and a baseball in weight, and it’s far smaller and harder than a football.

Why the dimensions matter

A taller seam gives spinners and seam bowlers more to grip and more surface to disturb the air with, which is the mechanical basis of swing. Weight affects bounce too: a heavier ball holds its line better off a hard, true pitch. And the hardness is exactly why cricket at senior level requires a helmet, pads, and gloves. This isn’t a soft ball, and it doesn’t behave like one.

How a ball is actually built

Inside is a cork core wound tightly with twine. Around that goes four pieces of leather stitched together, raised into the seam that bowlers spend years learning to use. Dukes, Kookaburra, and SG make the balls used at top level, and each brand’s seam height and lacquer recipe is different enough that players notice: Dukes balls are known for holding their seam and swinging longer in English conditions, Kookaburra tends to go softer and stop swinging sooner, which is part of why pitches and ball choice get debated so much in Test cricket.
