Fetal Weight at 20 Weeks in Grams
At 20 weeks of pregnancy, the average fetal weight is around 300 grams (0.3 kg). This is often the halfway point in pregnancy, and babies are growing rapidly. By now, your baby’s organs are developed, and ultrasound scans can provide accurate estimates of fetal weight. This is also when many parents start paying more attention to the fetal weight chart.
How to Calculate Fetal Weight
Healthcare providers use ultrasound imaging to estimate fetal weight. Common formulas, such as the Hadlock method, use measurements of the head, abdomen, and femur length.
Key parameters used:
- Biparietal Diameter (BPD)
- Head Circumference (HC)
- Abdominal Circumference (AC)
- Femur Length (FL)
These values are input into standard equations to calculate fetal weight. Though it's an estimate, it offers valuable insight into your baby’s development.

It’s helpful to have both grams and kilograms available to better understand fetal growth. This pregnancy fetal weight chart provides reference points to ensure your baby is on track.

Include high-protein snacks: Peanut butter toast, cheese cubes, and boiled eggs are good options.
