Ideal Weight for 5 Foot 6
At 5 ft 6 in (168 cm), a man's ideal weight is about 63–65 kg (140–143 lb) and a woman's about 59–61 kg (130–135 lb) across the four formulas. Pick your sex and add your age below.
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).

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 at 5 Foot 6
At 5 ft 6 in (168 cm), medium frame, a man's ideal weight is about 63.4–64.7 kg (140–143 lb) and a woman's about 59.0–61.3 kg (130–135 lb) across the four formulas. Pick your sex above and add your age for a figure tuned to you.
Men and Women at 5 Foot 6
Five foot six is 66 inches — six above the 5-foot base. For a man the four formulas land within a narrow band: Robinson 63.4 kg, Devine 63.8 kg, Hamwi 64.4 kg and Miller 64.7 kg, averaging 64.1 kg (141 lb). For a woman they run from Hamwi at 59.0 kg up to Miller at 61.3 kg, averaging 59.7 kg (132 lb). The tightness of the male band is a feature of average heights — the formulas only diverge sharply as you get taller. Every figure here is a straightforward arithmetic estimate from height and sex.
From Estimate to Target
Because the formulas agree closely at this height, the average is a dependable anchor — but the healthy BMI range shown in the calculator is still the better target when you want a band to aim within. To act on a figure, the Goal Weight Calculator maps a realistic timeline, and the TDEE Calculator gives the daily calories behind it. A different height? The Ideal Weight Calculator handles any stature from 5 ft to 7 ft.
Figures use the Devine, Robinson, Miller and Hamwi ideal-body-weight equations (Pai & Paloucek, 2000). They are population averages, not medical advice, and do not account for muscle mass or individual health conditions.
