                                Wild grape berries are typically only about 6 millimeters (1/4 inch) in diameter, while their cultivated counterparts can be much larger, with some reaching up to 30 millimeters. This vast difference highlights the factors that determine precisely how large is a grape in diameter, making it more than a simple measurement.
