Ideal weight by height · four classic formulas

Ideal weight for a 5'10" (178 cm) man

Quick answer

At 5'10" (178 cm), the four classic ideal weight formulas give 155 to 165 lb (70.3 to 75 kg) for a man. The weight range for a BMI of 18.5 to 24.9 at this height is 129 to 174 lb.

Lowest of four, Miller: 155lb; 70.3 kg
Highest of four, Hamwi: 165lb; 75 kg
Spread between formulas: 10lb; 4.7 kg
BMI 18.5 to 24.9: 129 to 174lb; 58.5 to 78.7 kg

Four formulas estimate an “ideal” body weight from height and sex alone. This page works them out for a man who is 5 ft 10 in, shows the arithmetic, and sets the answers beside the heights around it, 5'7" to 6'1". Treat the numbers as reference points to talk over with a professional, not as a goal.

The four formulas at 5'10"

Each formula is a base weight at 5 ft plus a fixed amount for every inch above it, a little differently for women and men. At 5'10" that is 10 inches above 5 ft.

What is specific to 5'10"

At 5 ft 10 in the formulas sit 10 inches above their 5 ft starting point. Hamwi (1964) gives the most at 165 lb (48 + 2.7 × 10 = 75 kg) and Miller (1983) the least at 155 lb (56.2 + 1.41 × 10 = 70.3 kg), a gap of 10 lb. For a man, each extra inch adds between 3.1 and 6 lb across the four, which is why the gap changes with height.

Against the weight range for a BMI of 18.5 to 24.9, which at this height is 129 to 174 lb: Robinson and Miller and Devine and Hamwi are inside it. The BMI range is 45 lb wide at 5'10", against 10 lb for the four formulas together, so it leaves more room.

One inch shorter, at 5'9", the four formulas give 152 to 159 lb; one inch taller, at 5'11", 158 to 171 lb. For a woman at the same 5'10", the same formulas give 146 to 151 lb, because each formula has its own base weight and per-inch step for each sex (see the 5'10" female page).

Ideal body weight formulas were first developed to help clinicians dose medication, not to say how anyone should look. They use height and sex only, so they cannot see your muscle, bone structure, age or health, and a man of 5'10" can be well outside them for good reasons.

Where the formulas come from

The Robinson (1983), Miller (1983), Devine (1974) and Hamwi (1964) formulas are the ones in our ideal weight calculator, which also takes any height. The weight range for a BMI of 18.5 to 24.9 is weight = BMI × height² for those two BMI values. Full citations are on the sources page, and the arithmetic is explained on how we calculate.

Frequently asked questions

What is the ideal weight for a 5'10" man?

The four classic formulas give 155 to 165 lb (70.3 to 75 kg) at 5'10": Robinson 157 lb, Miller 155 lb, Devine 161 lb, Hamwi 165 lb. They are estimates from height and sex alone, so they are a starting point for a conversation, not a goal.

Why do the formulas give different answers at 5'10"?

Each starts from a different base weight at 5 ft and adds a different amount per inch. At 5'10" that is 10 in above 5 ft, and the formulas end 10 lb apart, from Miller at 155 lb to Hamwi at 165 lb.

What weight range does a BMI of 18.5 to 24.9 give at 5'10"?

129 to 174 lb (58.5 to 78.7 kg) at 178 cm. BMI ignores muscle and frame, so it is a screening number, not a diagnosis.

Should I aim for the number on this page?

Not on the strength of a formula. They were written to help dose medication and know nothing about your muscle, frame, age or health. A doctor or registered dietitian can tell you what weight is right for you.
