Biparietal Diameter (BPD) is a crucial measurement included in fetal ultrasound. Through this measurement, doctors can assess the baby’s development and estimate the baby’s weight and size at birth.

The fetal length and weight chart by week is a comprehensive reference guide that allows expectant mothers to monitor their baby’s development during pregnancy. This enables mothers to make necessary adjustments to their diet, exercise routines, and overall lifestyle to ensure optimal health for themselves and their baby.

If the biparietal diameter, the fetal head measurement, is larger than normal, a vaginal delivery could pose significant risks for both the mother and baby during labor. However, for more precise assessments, doctors will combine the biparietal diameter measurement with other fetal parameters, such as abdominal circumference and femur length.
