How do I calculate BMI from pounds and feet?

Convert height to inches (feet x 12 + inches), then use: BMI = (weight in lbs / height in inches squared) x 703. Or let this calculator do it — enter lbs and feet/inches, and the math is instant.

What's a normal weight for 5'10"?

For someone 5'10" (178 cm), the healthy BMI range (18.5–24.9) corresponds to roughly 129–174 lbs (58.5–78.9 kg). This is a wide range because body composition varies significantly between individuals.

Is BMI different for tall people?

BMI tends to overestimate body fatness in tall people and underestimate it in short people, because it uses height squared rather than cubed. A 6'4" person and a 5'4" person at the same BMI have quite different body proportions. Some researchers advocate for a corrected formula for very tall or short individuals.
