Cricket balls, originating in 16th-17th century England, have evolved from handmade, inconsistent spheres to standardized equipment. Modern balls feature a cork and twine core, leather casing, a stitched seam, and a coating. Their hardness is a result of centuries of tradition and the game's physical demands, ensuring they are robust and hard-wearing. Technical standards formalized in 1994 ensure consistency across manufacturers and fairness globally, with specific weight and circumference requirements for men's, women's, and junior cricket.
