Fetal Weight Calculator

Estimate fetal weight (EFW) from ultrasound biometry using Hadlock and Shepard formulas. Supports cm/mm, optional gestational age with approximate P10–P90 reference, and a simple small/normal/large tip. For reference only—not a diagnosis.

Inputs

  • AC is most important for weight; AC+FL or BPD+AC is enough to compute.
  • Adding BPD/HC enables more Hadlock variants.

Notes

  • Typical ultrasound EFW error is about ±10–15%.
  • Growth trend across visits matters more than one estimate.
  • All calculations run locally in your browser.
