Healthy range (lb): 124.9 – 168.1

What you entered

Height (cm): 175

1
Convert height to metres
175 ÷ 100= 1.75 m
2
Lower bound (BMI 18.5)
18.5 × 1.75²= 56.7 kg
3
Upper bound (BMI 24.9)
24.9 × 1.75²= 76.3 kg

Result

Healthy range (kg): 56.7 – 76.3

At 175 cm, a healthy weight range is 56.7 – 76.3 kg (124.9 – 168.1 lb).

Healthy weight range by height

These ranges are the weights that put BMI between 18.5 and 24.9 at each height. Anything inside the range is a healthy weight by the BMI definition.

Height	Height (ft/in)	Healthy range (kg)	Healthy range (lb)
150 cm	4 ft 11 in	41.6 - 56.0	92 - 124
155 cm	5 ft 1 in	44.4 - 59.8	98 - 132
160 cm	5 ft 3 in	47.4 - 63.7	104 - 141
165 cm	5 ft 5 in	50.4 - 67.8	111 - 149
170 cm	5 ft 7 in	53.5 - 72.0	118 - 159
175 cm	5 ft 9 in	56.7 - 76.3	125 - 168
180 cm	5 ft 11 in	59.9 - 80.7	132 - 178
185 cm	6 ft 1 in	63.3 - 85.2	140 - 188
190 cm	6 ft 3 in	66.8 - 89.9	147 - 198

A range this wide covers very different body compositions. Waist measurement is often a better single indicator than weight alone. General wellness information only, not medical advice. Discuss any health decision with a qualified clinician.

A range, not a single target number

Rather than a single 'ideal weight,' this calculates the full span of weights that fall within the WHO's healthy BMI band for your height — a more realistic goal than chasing one exact number.

Why a range makes more sense

Two people of the same height can be equally healthy at different weights depending on frame size and muscle mass — a range acknowledges that natural variation better than a single figure does.

Frequently asked questions

What is a healthy weight for my height?

Multiply your height in metres squared by 18.5 (lower bound) and 24.9 (upper bound). For 170 cm (1.7 m): 1.7² = 2.89, so 53.5–72.0 kg (118–159 lbs). For 5'10" (1.78 m): 58.6–78.9 kg (129–174 lbs). This is the WHO healthy BMI range.

Is it better to be at the low or high end of the range?

Neither extreme is automatically better. Being at the low end while sedentary may mean low muscle mass. Being at the high end with regular strength training may mean healthy muscle. Research shows the lowest mortality risk is around BMI 22–25 — roughly the middle to upper-middle of the range.

Does age affect healthy weight?

Somewhat. Adults over 65 may benefit from a slightly higher BMI (23–27) — some studies show modest overweight is protective against frailty in older adults. For children and teens, age-specific growth charts replace fixed BMI ranges entirely.
