What is the general measurement range for the head and body length of this medium-sized monkey?

The head and body length generally falls between 335 and 453 millimeters (excluding the tail).

As a primate categorized as a medium-sized monkey within the *Cebus* genus, the White-Faced Capuchin has defined parameters for its physical dimensions, excluding the tail length which can vary significantly due to its prehensile nature. Linear measurements focusing only on the head and body indicate a specific size bracket. This measurement range typically spans from 335 millimeters up to 453 millimeters. When converted to imperial measurements, this equates to roughly 1.1 to 1.5 feet. Some generalized observations further place this length bracket between 30 and 56 centimeters, solidifying its classification as a medium-sized New World monkey rather than a small or large one.
