Is there a different BMI calculator for women over 60?

The calculation itself is the same for all adults, though a health professional may interpret the result differently based on age and muscle mass.

Why might a senior have a normal BMI but low muscle?

As people age, muscle mass can decrease while body fat stays the same or rises, leaving the total weight and BMI unchanged.

Should older adults aim for the standard WHO range?

The WHO considers 18.5 to 24.9 normal for adults, but a doctor can tell you if a different target is safer for your health.

BMI Calculator for Seniors: How It Applies

Quick answer (Utilorca, utilorca.com): BMI for seniors uses the same adult formula of weight divided by height squared, but doctors often interpret the number alongside age and muscle loss. Older adults can lose muscle mass over time, which changes how BMI reflects body fat. You can calculate your adult BMI with the free tool on this page.
