Geriatric BMI Calculator for Seniors (65+)

Your details

This calculator is optimised for adults aged 65 and over. Results below 65 will note that standard adult cut-offs may be more appropriate.
years
Used to apply the correct waist circumference risk thresholds (35 in / 88 cm for women, 40 in / 102 cm for men).
Your body weight in the selected unit.
kg
Your standing height in the selected unit.
cm
Measured at the narrowest point between your lowest rib and hip bone. Leave 0 to skip. Used to flag elevated visceral-fat risk independent of BMI.
cm
People of Asian descent typically have higher metabolic risk at a lower BMI. The Asian variant uses 22.0-26.0 as the healthy senior range.

Your BMI is 25.0 - healthy weight by senior-adjusted standards.

  • Your BMI falls within the senior-adjusted healthy range, which is associated with lower mortality risk in adults 65 and over.
  • Maintaining this range through adequate protein intake and resistance exercise supports muscle mass and bone density.
  • BMI does not measure muscle mass or fat distribution. For older adults, pairing it with waist circumference, handgrip strength, or a SARC-F frailty screen gives a fuller picture.

Next stepSchedule a routine health review with your GP to discuss your overall cardiometabolic risk, including blood pressure, lipid profile, and blood glucose.
