Background: Estimated fetal weight (EFW) is used as a guidence for management of labor. Several methods are used including ultrasound and fundal height measurements. The usual method is using Johnson�s formula but Risanto�s formula is now developing. Objective: To compare the accuracy of Risanto�s and Johnson�s formulas in determining estimated fetal weight. Design and method: This is a cross sectional study. Six hundred and sixty five pregnant women from Sardjito and affiliated hospital between 37-42 weeks of gestation are used. Fundal height is measured from the symphisis to the top of uterine fundus, using inverted unelastic flexible tape. EFW based on Risanto�s and Johnson�s formulas are compared with the actual birth weight. Wilcoxon analysis is used for statistic analysis. Result: Mean EFW Risanto is 3056 ± 322.5 grams and EFW Johnson is 3136 ± 392.2 grams and mean birth weight is 3021 ± 341.1 grams. The mean difference between EFW Risanto and birth weight is 100.8±86.1 grams and mean difference between EFW Johnson and actual birth weight is 156.1±107.3 grams. The difference bethween delta EFW Risanto�s and EFW Johnson�s is statistically significant (p=0,001). Conclusion: This study shows that Risanto�s formula is more accurate than Johnson�s.
