How the Formulas Get There
All three medical formulas start from a base at 5 feet and add weight per inch. For women, Devine uses 45.5 kg + 2.3 kg per inch over 5 feet; at 67 inches that is 45.5 + 2.3 x 7 = 61.6 kg. Robinson (49 + 1.7 per inch) and Miller (53.1 + 1.36 per inch) use the same structure with different constants.
Adjusting for Frame Size
Frame size shifts the estimate by about 10% in either direction. For a 5'7" woman the Devine figure becomes roughly 122 lbs with a small frame and 149 lbs with a large frame. Wrap your thumb and middle finger around your wrist: overlapping fingers suggest a small frame, just touching a medium frame, and a gap a large frame.
A Range, Not a Target
These formulas were built for medication dosing and population studies, not personal goals. Energy, blood pressure, and fitness matter more than any single number — treat 118-159 lbs as the wide healthy zone and the formula values as reference points inside it.
Frequently Asked Questions
What is a healthy BMI for a 5'7 woman?
The same 18.5-24.9 range as any adult, which corresponds to 118-159 lbs at that height.
Does age change ideal weight?
The standard formulas ignore age. Body composition shifts with age, so older adults often focus on strength and waist measurements alongside weight.
Is 136 lbs right for every 5'7 woman?
No — it is a statistical midpoint. Muscle, bone density, and frame size move a healthy individual figure by 10% or more.
What about 5'7 in centimeters?
Five foot seven is 170 cm. Enter it in metric mode above and the same formulas apply.
