Frequently Asked Questions – Ideal Weight Calculator

What are the different ideal weight formulas and how do they differ?

Robinson (1983): Updated version of older formulas, widely used for general population. Miller (1983): Modification of Robinson formula with slight adjustments. Hamwi (1964): Originally developed for medical use, still common in clinical settings. Devine (1974): Developed for pharmaceutical dosing, tends to give slightly higher weights. Each formula has different base weights and height adjustments.

How do I determine my body frame size?

Body frame size can be estimated by wrist circumference or elbow breadth. For wrist measurement: Men – Small: <16.5cm, Medium: 16.5-18.5cm, Large: >18.5cm. Women – Small: <14cm, Medium: 14-15.9cm, Large: >15.9cm. You can also extend your arm and measure the distance between the prominent bones on either side of your elbow for elbow breadth method.

Is ideal weight the same as healthy weight?

Not necessarily. Ideal weight formulas provide estimates based on height and frame size, but healthy weight depends on many factors including muscle mass, bone density, body fat percentage, and overall health markers. Athletes with high muscle mass may weigh more than “ideal” but be very healthy. Focus on overall health rather than just the number on the scale.

How should I use ideal weight calculations for goal setting?

Use ideal weight as a general guideline, not an absolute target. Consider the range rather than a specific number. If your current weight is significantly different from the ideal range, aim for gradual changes of 0.5-1kg per week. Focus on sustainable habits like balanced nutrition and regular exercise. Consider body composition goals (muscle vs. fat) rather than just total weight.

Do ideal weight formulas work for everyone?

Ideal weight formulas have limitations. They don’t account for muscle mass, body composition, ethnicity differences, or individual health conditions. They work best for average adults but may not be suitable for: athletes with high muscle mass, elderly individuals, people with certain medical conditions, or those with unusual body proportions. Always consult healthcare providers for personalized advice.

What factors besides height affect ideal weight?

Several factors influence ideal weight: Body frame size (bone structure), muscle mass (athletes may weigh more), age (metabolism and body composition changes), gender (different muscle/fat ratios), ethnicity (different body composition patterns), activity level, and health conditions. Consider these factors when interpreting ideal weight calculations.
