What Is Ideal Weight?

What Is an Ideal Weight Calculator and How Does It Work?

An ideal weight calculator uses your height, age, and gender to estimate the healthy weight range for your body. For Indians, the ideal weight range uses BMI cutoffs of 18.5–22.9 — lower than Western standards of 18.5–24.9. At 165 cm, the Indian ideal weight range is approximately 50–62 kg. This is not a single number — it is a range that gives you a realistic, health-focused target.

The idea of an ideal weight has existed in medicine for over a century. Early ideal weight charts were based on insurance industry mortality data — they associated certain weight ranges with lower death rates and used this to define “desirable” weight. Over time, these evolved into the height-weight tables and eventually the BMI-based ranges we use today.

For Indians and South Asians, standard Western ideal weight tables are insufficient. Research consistently shows that South Asians carry more visceral fat (fat around the organs) at any given BMI than Western populations — and that metabolic complications like type 2 diabetes and cardiovascular disease develop at lower body weights. Using Indian-specific BMI cutoffs to define ideal weight produces a range that is genuinely protective of your metabolic health.

It is also important to understand that ideal weight is a range, not a target number. Within that range, different weights may be healthier for different people depending on muscle mass, bone density, age, and body composition. The goal is not to hit a specific number on the scale but to achieve a body composition that supports good health and metabolic function. A person at the lower end of the range with high muscle mass will have a very different health profile to someone at the upper end with low muscle and high body fat — even at the same weight.

For Indians, achieving and maintaining an ideal weight is particularly important given the elevated rates of type 2 diabetes, hypertension, and cardiovascular disease in the population. Even a modest movement toward the lower end of the healthy BMI range produces measurable improvements in blood sugar, blood pressure, and cholesterol for most Indians.

Ideal Weight by Height

Ideal Weight for Indians by Height — Men and Women

Using Indian BMI cutoffs of 18.5–22.9, here are ideal weight ranges for common heights:

How It Is Calculated

How Ideal Weight Is Calculated — The Formulas

There are three main methods for calculating ideal body weight. Each has strengths and limitations:

Method 1 — Indian BMI Range (most recommended)

The most accurate method for Indians. Multiply height in metres squared by 18.5 and 22.9:

Example for 168 cm: (1.68)² = 2.8224. Lower: 2.8224 × 18.5 = 52.2 kg. Upper: 2.8224 × 22.9 = 64.6 kg. Ideal range: 52–65 kg.

Method 2 — Devine Formula

A widely referenced clinical formula developed in 1974, giving a single-point estimate rather than a range:

For a man who is 175 cm (5 ft 9 in): 50 + 2.3 × 9 = 70.7 kg. For a woman at 163 cm (5 ft 4 in): 45.5 + 2.3 × 4 = 54.7 kg. The Devine formula was not developed for South Asian populations and tends to overestimate ideal weight for Indians.

Method 3 — Peterson Formula (updated)

A 2016 study by Peterson et al. found that older ideal weight formulas significantly overestimate healthy weight for Asian populations and proposed a revised formula with lower targets. The DialFit Ideal Weight Calculator integrates Indian BMI cutoffs to give results relevant to South Asians.

Beyond the Scale

Why Ideal Weight Is More Than a Number

Reaching your ideal weight on the scale does not automatically mean you are at your healthiest. Here is what to assess alongside weight:

Body fat percentage

Two people at the same weight and height can have very different body compositions. One may have 18% body fat and high muscle mass — the other may have 32% body fat and low muscle. Only body fat percentage reveals this difference. For Indians, a healthy body fat percentage is 14–24% for men and 21–31% for women. Use the Body Fat Calculator to check yours.

Waist circumference

Indians are predisposed to visceral fat accumulation — fat stored around organs in the abdomen. A person can be at their ideal weight but have a high waist circumference, indicating dangerous visceral fat. For Indian men, healthy waist is below 90 cm. For Indian women, below 80 cm. Use the Waist-Hip Ratio Calculator to assess abdominal fat risk.

Metabolic health markers

Blood sugar, blood pressure, and lipid levels are direct indicators of metabolic health — more meaningful than weight alone. An Indian at their ideal weight but with fasting blood glucose above 100 mg/dL is at significant risk. Check your Diabetes Risk Score regardless of your weight status.

Muscle mass

Reaching ideal weight by losing muscle — rather than fat — is counterproductive. Muscle preserves metabolic rate, supports bone health, and improves insulin sensitivity. Use the Protein Calculator to ensure adequate protein intake during weight loss, which is the primary driver of muscle preservation.

How to Reach It

How to Reach Your Ideal Weight Sustainably

Reaching your ideal weight requires an approach that loses fat while preserving muscle — not just reducing the number on the scale. Here is the evidence-based process:

• Calculate your TDEE. Use the TDEE Calculator to find your maintenance calories. This is the baseline for all further calculations.
• Set a calorie deficit of 300–500 kcal/day. This produces 0.25–0.5 kg of fat loss per week — the optimal rate for preserving muscle. Use the Weight Loss Calculator to project your timeline and target intake.
• Eat 1.6–2.2g protein per kg body weight. Protein is the most critical variable for preserving muscle during fat loss. Higher protein intake also increases satiety, making the calorie deficit easier to sustain. Indian sources: paneer, dal, soya chunks, eggs, chicken, Greek yogurt.
• Add resistance training 2–3 times per week. Strength training signals your body to preserve muscle during a calorie deficit and improves insulin sensitivity — particularly beneficial for Indians at risk of type 2 diabetes.
• Track body fat, not just weight. Weight fluctuates by 1–3 kg daily due to water, digestion, and hormonal cycles. Monthly body fat percentage measurements using the Body Fat Calculator give a far more accurate picture of your progress.
• Recalculate every 4–6 weeks. As you lose weight, your TDEE decreases. Recalculating your calorie targets monthly keeps your deficit accurate and your results progressing toward your ideal weight.
