Ideal Weight Calculator for Women – Devine & Robinson Formula

Body weight isn’t always easy to understand when two women of the same height can have different body shapes and weights. An ideal weight calculator for women helps you determine an appropriate weight based on your height. Yet, there may be other elements that play an important role when calculating a healthy weight for a particular woman, such as her age, muscle mass, and body frame.
In this tool, you will be provided with weight estimates using common weight equations like the Devine and Robinson formulas in kilograms and pounds. You can also use this tool to compare your result with your healthy body mass index. Below, you will learn about these weight formulas, have a look at the height-weight table, and consider factors to consider for realistic weight.

How to Calculate Ideal Body Weight for Women?

Different women will have different body weights even if they are of the same height. However, a few commonly used formulas can help estimate body weight based on height. The Devine and Robinson formulas are two methods that provide a starting point for understanding these weight estimates.

Devine Formula for Women

Among traditional weight calculations, the Devine formula is widely known for estimating body weight. It was originally developed for medical dosing, so its result shouldn’t be treated as a perfect health target.

Formula:

Ideal Weight (kg) = 45.5 + 2.3 × (Height in inches − 60)

Example for a 5’5″ woman:

  • Height: 65 inches
  • Extra inches: 65 − 60 = 5
  • Calculation: 45.5 + (2.3 × 5)
  • Estimated weight: 57 kg (125.7 lbs)

Robinson Formula for Women

Another commonly used method is the Robinson formula, which gives slightly different estimates. Like Devine, it uses height rather than individual body composition.

Formula:

Ideal Weight (kg) = 49 + 1.7 × (Height in inches − 60)

Example for a 5’5″ woman:

  • Height: 65 inches
  • Extra inches: 5
  • Calculation: 49 + (1.7 × 5)
  • Estimated weight: 57.5 kg (126.8 lbs)

An Ideal Weight Calculator for Women will show you both predictions so that it becomes clear how the same height can yield two different weights. 

What Is an Ideal Weight Calculator for Women?

Women have different body types, and what works as a good body weight for one individual might not work well for another. With our Ideal Body Weight Calculator for women, it becomes easier to determine an ideal body weight using the individual’s height. The calculator employs common equations, such as those by Devine and Robinson, to calculate the body weight of individuals in kilos and pounds. Comparing the two gives you a better understanding of your body weight. There are various considerations when determining body weight.

How to Set a Realistic Weight Goal?


Once the estimates are clear, choosing a personal goal becomes the next concern. Rather than chasing one number, a realistic approach considers comfort, health, and daily habits.

  • Consider Your Body Type: Every woman has a different body shape and bone structure, which can influence her natural weight. For example, women with broader frames may weigh more than those with smaller frames, even at the same height.
  • Check Your Healthy Weight Range: Knowing the healthy range of BMI is essential, as it gives an idea of a weight that is good for a certain height. You can cross-check your score on our Female BMI Chart.
  • Set Achievable Goals: Small and realistic weight loss goals can be more realistic to accomplish compared to attempting to achieve larger goals in the short term. This will give the body time to adapt to new healthy behaviors. 
  • Focus on Body Composition: Body weight consists of muscle, fat, bone, and water; thus, body weight doesn’t reveal everything. Others may have more muscle but still maintain normal body composition. You can check this using our Body Fat Calculator for Women.
  • Monitor Your Progress: Your weight will vary during the day due to meals and hormonal changes. But by monitoring your progress over the course of many weeks, you will be able to see if your efforts have had any impact. 

Final Words

A healthy weight will become easier to understand if one considers such factors as formulas, BMI, and body composition. The Ideal Weight Calculator for Women might be a starting point even if the formula cannot be applied to all kinds of body shapes. Devine and Robinson offer their own calculations that differ from each other; the range of BMI is wider.
