  • Your current weight
  • Your height
  • Your baby's estimated due date (EDD)

Enter these values into the calculator and click "Calculate" to see your baby's estimated size and position.

How Fetal Growth is Measured

Fetal growth is typically measured using several key parameters:

  • Crown-rump length (CRL): Measured in the first trimester
  • Biparietal diameter (BPD): Distance between the baby's skull bones
  • Head circumference: Around the baby's head
  • Abdominal circumference: Around the baby's belly
  • Femur length: Length of the baby's thigh bone
  • Estimated fetal weight (EFW): Based on ultrasound measurements

Formula used:

EFW = (CRL × BPD × HC × AC × FL) × 0.00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
