(HealthDay News) — Measuring weight is key to calculating your body mass index (BMI), says the Centers for Disease Control and Prevention.

To measure weight accurately at home, the CDC recommends:

  • Use a digital scale. Avoid scales that are spring-loaded.
  • Place the scale on a firm floor, rather than on carpet.
  • Remove shoes and heavy clothing.
  • Stand with both feet in the center of the scale.
  • Record the weight to the nearest decimal fraction.
