A unified protocol is essential to ensure that fetal ultrasound measurements taken in multicentre research studies are accurate and reproducible. This paper describes the methodology used to take two‐dimensional, ultrasound measurements in the longitudinal, fetal growth component of the INTERGROWTH ‐21 st P roject. These standardised methods should minimise the systematic errors associated with pooling data from different study sites. They represent a model for carrying out similar research studies in the future.
