The weight of an international tournament leather cricket ball is typically between 5.5 to 5.75 ounces (155.9 to 163 grams). The exact weight may vary slightly based on the manufacturer and specific tournament regulations. The International Cricket Council (ICC), which is the governing body for international cricket, has set specific regulations for cricket balls, including their weight, size, and construction, to ensure consistency and fairness in the game.

A standard leather cricket ball used in international tournaments typically has the following design features:

1. Shape: The ball is spherical in shape, with a circumference of approximately 8.81 to 9 inches (22.4 to 22.9 cm) for adult cricket and a slightly smaller size for junior cricket.
2. Material: The outer covering of the ball is made of high-quality leather, usually cowhide, which is stitched in a specific pattern. The stitching is typically done using waxed thread and forms a prominent seam around the circumference of the ball.
3. Color: The ball is traditionally red in color, although white and pink balls are also used in certain formats of the game, such as limited-overs matches and day-night matches.
4. Weight: The ball weighs between 5.5 to 5.75 ounces (155.9 to 163 grams) and is filled with layers of cork and rubber, which provide the required weight and bounce for the game of cricket.
5. Branding: The ball may have branding or logo markings from the manufacturer or the tournament sponsor on one or both sides.
6. Grip: The ball may have a rough texture to provide grip for the bowler to hold and impart spin during delivery.
