Understanding ideal weight at 5'6"
"Ideal weight" is a range, not a single number. At 5'6", the four classic formulas span roughly 140 lbs (63 kg) to 143 lbs (65 kg) because each was fitted to a different population. The healthy BMI range is the widest and most clinically used benchmark. None of these adjust for muscle mass or frame.
