FAQ
Why do these 4 formulas give different results?
Each formula was built in a different decade using different population data — some variation is normal. Taking the average is the most balanced approach.
Does body frame (small/large) matter?
Yes — these formulas are based only on height and don't account for body frame/muscle mass. An athletic build person's "ideal" weight can exceed the formula's number, and that's completely normal.
What's the difference between BMI and ideal weight?
BMI gives a range (healthy 18.5-24.9), ideal weight calculators give a specific number. It's better to look at both together.
