A BMI of 29.4 at 170 cm is classified as Overweight. The WHO healthy BMI range is 18.5 – 24.9, which for your height translates to roughly 53.5 – 72.0 kg (117.9 – 158.6 lbs).

The mid-point of the healthy BMI range (BMI 22) for 170 cm is approximately 63.6 kg (140.2 lbs). The full healthy range spans roughly 53.5 – 72.0 kg. Body composition matters more than the exact number — a muscular person can sit at the top of the range and be perfectly healthy.

How does BMI relate to body fat percentage at 85 kg?

BMI does not measure body fat directly. Two people at 170 cm and 85 kg can have very different body compositions. A trained athlete at this weight may have 12 – 15% body fat, while a sedentary adult may have 25 – 30%. Use the Body Fat Calculator for a more precise estimate.

Is BMI accurate for everyone at 170 cm tall?

BMI is a population-level screening tool. It systematically over-classifies muscular athletes as overweight and under-classifies older adults with sarcopenic obesity. For an individual assessment at 170 cm, combine BMI with waist circumference (men < 94 cm, women < 80 cm at low risk) and body fat percentage.

How much weight would I need to lose or gain to reach a healthy BMI at 170 cm?

If your BMI is below 18.5, gaining weight up to the 53.5 kg (117.9 lbs) threshold puts you in the healthy band. If above 25, losing weight toward 72.0 kg (158.6 lbs) does the same. Aim for 0.25 – 0.5 kg per week for sustainable change.
