is a bowling pin as tall as it is round
Pin specifications are set by the United States Bowling Congress (USBC). World Bowling, formerly World Tenpin Bowling Association, has adopted the USBC specifications. Pins are 4.75 inches (121 mm) wide at their widest point and 15 inches (380 mm) tall. They weigh 3 pounds 6 ounces (1.5 kilograms), pins weighing up to 3 lb 10 oz (1.6 kg) are approved. The weight of the pin was originally based on the idea that a single pin should be around 24 percent the weight of the heaviest bowling ball within regulation, 16 lb 0 oz (7.3 kg).
