Aim and objectives: Hence this study is being taken up for clinical as well as USG estimation of birth weight close to delivery date and to find their accuracy when compared to actual birth weight of the neonates. Materials and method: This Prospective cross-sectional comparative study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Pimpri Pune from September 2020 to September 2022. Singleton pregnancy with vertex presentation at term (37-40 weeks) who had gestational age confirmed by dates and early trimester ultrasound scan. Results: Among study population, 86.4% had a liquor between 8-15 cm. There were 4.5% participants each with liquor less than 8 cms, between 16-20 cms and above 20 cm. Weight estimation by the two methods had no statistically significant difference. However, clinical method was found to be slightly more accurate for estimating the antenatal foetal weight. Conclusion: Clinical and fetal weight estimation is one of the easiest and cheapest method which can be applied in any setup like in rural areas, where facilities for ultrasound machine may not be available. So, clinical method does have the advantage over the other.
