What is the average maximum length of a normal umbilical cord?

The average maximum length of a normal umbilical cord is generally recognized to fall within the range of 55 to 60 cm. This length is significant because the umbilical cord plays a crucial role in fetal development, providing oxygen and nutrients from the placenta while removing waste products. A cord of this average length allows for sufficient mobility for the fetus within the amniotic fluid and helps prevent complications related to restricted movement.

Umbilical cords can vary in length significantly among different individuals, and understanding the normal range is vital for assessing fetal well-being. A cord that is too short may lead to complications such as cord accidents, while an excessively long cord could contribute to issues like cord knots or entanglement. Hence, the average length of the umbilical cord being in the range of 55 to 60 cm represents a standard benchmark in neonatal assessments.
