Abstract: It has become increasingly important to estimate fetal weight especially for prevention of prematurity, evaluation of fetopelvic disproportion, induction of labour before term and detection of IUGR. The study was a prospective study conducted at J. J. group of hospitals on 1500 pregnant women selected by simple random sampling who attended the antenatal clinic or were admitted in the antenatal ward during August 2015 to December 2017. Birth weight was estimated and comparative analysis were done using sonographic fetal growth parameters at or near term or in early labour by Hadlock’s formula and clinically by Johnson’s formula and Dare formula correlated after birth with actual birth weight. My study suggested that Ultrasonography is the most accurate in terms of Overall Percentage Error. Johnsons Formula has least accuracy as only 18.1 cases are within 20% error and Hadlock has maximum accuracy as 97.7% cases are within 20% error.
