Ideal Body Weight for Women According to Height
Last updated on November 28th, 2025 at 03:06 pm
According to the National Health and Nutrition Examination Survey (NHANES), 27.5% of women are overweight, and 11.5% have severe obesity. These data highlight the importance of understanding their ideal body weight ranges. Hence, let’s explore detailed ideal weight ranges for women in both kilograms (kg) and pounds (lb), along with a simple formula to measure it.
We’ll also discuss some tips on maintaining a healthy weight. But before that, let’s discuss what ideal body weight is.
What is Ideal Body Weight?
Ideal body weight (IBW) is the weight at which your body functions effectively, reducing health risks like diabetes, heart disease, joint problems, and other issues. It’s not the same for everyone. It varies based on factors like age, height, muscle mass, and overall body composition. Unlike general weight ranges, IBW focuses on what’s healthiest for your unique body, helping you feel energised and confident.
How to Calculate Your Ideal Body Weight?
You can calculate your ideal body weight using two popular formulas: the Devine formula and the Hamwi formula. Both are simple and widely used, but the Devine formula is a highly used method.
Devine formula
- In kilograms (kg): 45.5 + 2.3 (height in inches – 60)
- In pounds (lb): 100 + 5 (height in inches – 60)
For example, if you’re 5’2” (62 inches) tall:
- To calculate your ideal weight in KG: “45.5 + 2.3 (62 – 60) = 45.5 + 2.3 * 2 = 45.5 + 13.8 = 50.1 kg”
- To calculate your ideal weight in LB: “100 + 5 (62 – 60) = 100 + 5 * 2 = 100 + 30 = 110 lb”
Hamwi formula
- In kilograms (kg): 45 + 2.2 (height in inches – 60)
- In pounds (lb): 100 + 6 (height in inches – 60)
Example: If you’re 5’4” (64 inches) tall:
- To calculate your ideal weight in KG: “45 + 2.2 (64 – 60) = 45 + 2.2 * 4 = 45 + 8.8 = 53.8 kg”
- To calculate your ideal weight in LB: “100 + 6 (64 – 60) = 100 + 6 * 4 = 100 + 24 = 124 lb”
Note: This is a rough estimate; other factors, such as muscle mass and body fat percentage, also matter.

How to Use These Weight Ranges
Your ideal body weight is a starting point, not a strict rule. Each person has a different body, and factors like genetics, muscle composition, and lifestyle play a role. Here’s how to use these ranges effectively:
- Personalise Your Goals: If you’re muscular, your ideal weight might be higher. If you have a leaner frame, aim for the lower end.
- Look Beyond the Scale: Focus on body fat percentage, muscle mass, and how you feel rather than just the number on the scale.
- Consult a Professional: A dietitian or healthcare provider can help you determine the healthiest weight for your body type and lifestyle.
