There are over a thousand varieties of mangos that vary in shape from round to pear-shaped to narrow and oval, and that can weigh up to 4 pounds (1,814g). Mangos sold in markets are usually not differentiated by variety, but are generally 4 to 5 inches (10 to 12.5cm) in length and weigh about 8 ounces (227g). One exception is the Manila mango; these are a smaller, golden-yellow variety that are now appearing in markets.
