A water polo ball is a ball used in water polo and canoe polo, usually characterized by a bright yellow colour and ease of gripability, so as to allow it to be held with one hand despite its large size. Ball weight is 400-450 grams (14-16 ounces) and come in two main sizes: a size 5 (0.7 meters or 28 inches in circumference), intended for use by men, and a size 4 (0.65 meters or 26.5 inches in circumference), intended for women. Smaller balls are sometimes used by juniors for "mini-polo," though these miniature do not typically come in standard sizes and are often coloured green.
