Understanding ideal weight at 6'4"
"Ideal weight" is a range, not a single number. At 6'4", the four classic formulas span roughly 174 lbs (79 kg) to 201 lbs (91 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.
