Ideal Weight for 5 Foot 8
At 5 ft 8 in (173 cm), a man's ideal weight is about 67–70 kg (148–154 lb) and a woman's about 63–64 kg (138–141 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).
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 at 5 Foot 8
At 5 ft 8 in (173 cm), medium frame, a man's ideal weight is about 67.2–69.9 kg (148–154 lb) and a woman's about 62.6–64.0 kg (138–141 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 8
Five foot eight is 68 inches — eight above the 5-foot base the formulas build from. For a man, Robinson gives the lowest target at 67.2 kg, Miller 67.5 kg, Devine 68.4 kg and Hamwi the highest at 69.9 kg, averaging 68.2 kg (150 lb). For a woman, the four sit between 62.6 and 64.0 kg, averaging 63.5 kg (140 lb). Eight inches of increment is enough for a modest spread but not the wide fan you see at 6 ft and above. Each figure is an arithmetic estimate from height and sex — it does not account for how much of your weight is muscle.
Putting the Number to Work
Read the average as your anchor and the healthy BMI range shown in the calculator as the wider target band. From there, the Goal Weight Calculator turns a target into a week-by-week timeline, and the TDEE Calculator shows the daily calories that hold or change your weight. For any other height, the Ideal Weight Calculator covers 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.
