BMI Calculator for Seniors

Q: Why is the healthy BMI range different for seniors?

Studies show seniors have the lowest mortality at BMI 20-26.9, wider than the adult range of 18.5-23.9. Slightly higher weight can be protective in old age.

Q: What are the risks of low BMI in older adults?

Seniors with BMI under 20 face higher risks of sarcopenia (muscle loss), weakened immunity and falls, and should improve nutrition promptly.

Q: How do I use the BMI Calculator?

Open the page and fill in the input fields — results update automatically. Body mass index with healthy range by standard.

Q: Are the results accurate?

Results follow published international standards (WHO, ACE, IOM) and are for reference only.

Q: Can this replace medical advice?

No. Always consult a qualified healthcare professional for health decisions.

BMI bands: China vs WHO

Band	China (WS/T 428)	WHO	Risk
Underweight	<18.5	<18.5	Low (but nutritional risk)
Normal	18.5–23.9	18.5–24.9	Lowest
Overweight	24.0–27.9	25.0–29.9	Elevated
Obese	≥28.0	≥30.0	High (diabetes/CVD)

💡 BMI applies to adults 18+. It misclassifies muscular athletes (high muscle = high "overweight") and the elderly (muscle loss hides fat). China uses stricter cutoffs (24/28 vs 25/30) because Asians develop metabolic risk at lower BMI. Ponderal Index (kg/m³) is fairer for very tall/short people. Not for children — use growth percentile charts instead.
