Papaya fruits are smooth skinned. They vary widely in size and shape, depending on variety and type of plant. Hermaphrodite plants of commercial 'Solo' varieties in Hawaii usually produce fruits that are pear shaped and weigh approximately 12 to 30 oz (340 to 851 g). Female plants of 'Solo' varieties produce round fruits. Other papaya varieties produce variously shaped fruits, which may weigh up to 20 lb (9.1 kg). The fruits usually contain many seeds surrounded by a smooth yellow to orange-red flesh that is sweet in good varieties.
