Frequently Asked Questions

Ideal weight depends on height, gender, frame size, and muscle mass. As a rough guide, a medium-frame 5'10" man's ideal weight is approximately 155-170 lbs. A medium-frame 5'5" woman's ideal weight is approximately 125-140 lbs.

No single formula is perfect. The Devine formula is most widely used in clinical settings for drug dosing. The BMI-based range (18.5-24.9) gives the broadest healthy range. Use the average of all formulas for a reasonable target.

Large-framed individuals naturally weigh more due to bigger bones and larger body structure. Frame size adjustments add 10% for large frames and subtract 10% for small frames. Measure your wrist circumference to determine frame size.

How to Determine Your Frame Size
Wrist Measurement Method

Wrap your thumb and middle finger around your wrist just above the wrist bone (the bump on the outside).

Small Frame
Fingers overlap each other
Wrist < 6.5"
Medium Frame
Fingers just touch
Wrist 6.5" - 7.5"
Large Frame
Fingers do not touch
Wrist > 7.5"
How frame size affects ideal weight: Small frames support less weight, while larger frames support more. The calculator adjusts ideal weight by -10% for small frames and +10% for large frames, matching clinical guidelines.

About the Formulas
Devine Formula (1974)
Male: 50 + 2.3 kg per inch over 5 ft
Originally developed for medicinal dosage calculations. The most widely referenced formula in clinical settings.
Robinson Formula (1983)
Male: 52 + 1.9 kg per inch over 5 ft
A modification of the Devine formula, considered to provide more realistic estimates for most people.
Miller Formula (1983)
Male: 56.2 + 1.41 kg per inch over 5 ft
Tends to produce higher ideal weights for shorter individuals and lower for taller, reflecting a more gradual height-weight relationship.
Hamwi Formula (1964)
Male: 48 + 2.7 kg per inch over 5 ft
One of the earliest ideal weight formulas, commonly used in clinical nutrition for quick estimates.
Disclaimer

Ideal body weight formulas provide rough estimates based on height and gender. They do not account for muscle mass, body composition, age, ethnicity, or individual health conditions.

This is not medical advice. A healthy weight varies significantly between individuals. Athletes and muscular individuals may weigh more than these estimates suggest while being perfectly healthy. The BMI-based healthy weight range (18.5–24.9) is provided as an additional reference.

Always consult a healthcare professional for personalized weight and health guidance.
