Ideal Weight for a 6-Foot Man
For a 6 ft (183 cm) man, the four clinical formulas land between about 73 and 81 kg (161–178 lb), averaging 76.6 kg. Sex is pre-set to male — add your age and frame for your own figure.
Find Your Ideal Weight
Required: the ideal-weight formulas use biological sex (male or female) as a variable, so the estimate can’t be calculated without it.
Age adjusts the healthy BMI reference range for adults 65+ (senior guidelines use BMI 23–28).
Enter your height in centimeters (e.g., 170 cm)
Valid range: 152–214 cm (approx. 5 ft – 7 ft)
The ±10% frame adjustment is applied to all four formulas. Clinical medication dosing uses the unadjusted medium-frame value.
Women (>165 cm): Small <15.9 cm · Medium 15.9–16.5 cm · Large >16.5 cm
Valid range: 10–30 cm

Quick Answer
Ideal Weight for a 6-Foot Man
For a 6 ft (183 cm) man at a medium frame, the four clinical formulas span roughly 73.1–80.7 kg (161–178 lb), averaging about 76.6 kg (169 lb). The gender is pre-set to male above — add your age and, optionally, your frame size for a figure tuned to you.
The Four Formulas at 6 Feet
At 6 ft, the calculator works from a height of 72 inches — 12 inches above the 5-foot base every ideal-weight formula starts from. Each formula adds its own weight per inch over that base, which is why they fan out. Miller uses the shallowest increment and returns the lowest target at 73.1 kg; Robinson follows at 74.8 kg; Devine, the formula hospitals use for drug dosing, gives 77.6 kg; and Hamwi, the dietitian's rule of thumb, gives the highest at 80.7 kg. Average the four and you get about 76.6 kg (169 lb), which is the balanced default this tool shows. None of these is a diagnosis of a healthy weight — they are simply four arithmetic estimates from your height.
Reading the Result Against the BMI Range
Because these are height-only formulas, a single figure can land just outside the healthy BMI weight range for your height. When it does, treat the BMI range — shown beneath the formula breakdown — as the more reliable target, since it spans a band rather than a single point. The four formulas are most useful read together: the low-to-high spread tells you how much reasonable estimates disagree, and the midpoint gives you a sensible anchor. Once you have your number, the Goal Weight Calculator maps a realistic timeline to reach it, and the TDEE Calculator shows the calories that hold or change your weight.
This page pre-sets the calculator for a 6-foot man; if you are a different height, the Ideal Weight Calculator covers any stature from 5 ft to 7 ft.
