Knowing the Estimated Fetal Weight (EFW) in prenatal care is important to give appropriate pregnancy and delivery treatments. Since ultrasound device is unavailable in primary health care, fundal height measurement is used to calculate EFW. The Johnson-Toshack formula is commonly used in Indonesia while Risanto formula is a formula made by Indonesian researcher but still rarely used. This study aimed to determine which formula gave closer result to the baby's actual birth weight. Data was taken at Midwife Yeni's practice site since February until April 2019. All women who met the eligibility criteria were recruited. The fundal height was measured using a centimeter tape and the baby's weight was measured using a baby scale. All data was compared to find out which formula gave closer EFW result to the baby's actual birth weight. Both Johnson and Risanto formulas had no significant difference to the baby's birth weight (p value Johnson = 0.093; p value Risanto = 0.105). The mean difference between Risanto's EFW and baby birth weight (∆EFW Risanto) was lower than Johnson's (∆EFW Risanto = 103 gram; ∆EFW Johnson = 121 gram). The conclusion of this study is the Risanto formula gives closer EFW results to the baby's birth weight than the Johnson formula.
