Ideal Weight Calculator

Find Your Healthy Weight Range

Our free Ideal Weight Calculator helps you work out a healthy weight range based on your height, gender, and frame size. Enter your details above and get an instant result, calculated using recognised clinical formulas. This tool has been built with guidance from Dietician and Nutritionist in Delhi, Avni Kaul, founder of Nutri Activania, so you can understand exactly what your result means for your health.

What is Ideal Weight?

Ideal weight refers to an estimated healthy weight range calculated mainly from your height and gender, with an option to adjust for frame size. Rather than a single fixed figure, it represents a range within which the health risks linked to being underweight or overweight are generally lowest. It works best as a reference point used alongside other measures, such as BMI and body fat percentage, rather than in isolation.

How is Ideal Weight Calculated?

Our calculator draws on four established formulas, each taking a slightly different approach:

Robinson Formula (1983) – One of the most widely used and accepted methods
Miller Formula (1983) – A more recent adaptation giving slightly different figures
Hamwi Formula (1964) – The original clinical formula, still referenced today
Devine Formula (1974) – Commonly applied in clinical settings and medical dosing

Because each formula calculates results a little differently, we also show an average across all four, giving you a more balanced overall estimate.

Understanding Your Result

Alongside your ideal weight figure, the calculator also displays your healthy BMI range for your height. Viewed together, these two numbers give a clearer picture than either alone, since ideal weight is based on broader population data while BMI reflects your specific height-to-weight proportion.

Why Ideal Weight Is a Guideline, Not a Target

It’s worth keeping in mind that ideal weight formulas are built on general population averages and don’t factor in individual muscle mass, bone density, or body composition. Someone with a naturally muscular build may sit above their calculated ideal weight while remaining in excellent health. For this reason, treat your result as a useful starting reference rather than a number to chase strictly.

What to Do With Your Result

Where your current weight sits relative to your ideal range will shape your next steps:

If you’re above your ideal range, a structured, sustainable approach to weight loss can help you move towards a healthier range without extreme restriction.
If you’re below your ideal range, a guided plan focused on healthy weight gain can help you build weight steadily through the right nutrition.
If you’re already within range, the focus shifts to maintaining it through balanced, consistent eating habits.

Why Work With a Dietician for Your Weight Goals

A calculator gives you a useful figure, but reaching and maintaining a healthy weight depends on a plan built around your actual lifestyle and body. If your goal is to bring your weight down, our dietician for weight loss in Delhi programme offers a structured, sustainable approach tailored to you.

If your goal is instead to build weight in a healthy way, our dietician for weight gain in Delhi programme focuses on steady, muscle-supportive weight gain rather than quick fixes.

 Trustindex verifies that the original source of the review is Google.  Avni approaches nutrition and wellbeing in a genuinely scientific and highly customized way. Her knowledge is impressive, but what truly stands out is the personalized element—it's clearly not a rigid, one-size-fits-all plan. I really appreciate that the process is designed to be flexible and adaptable to individual preferences and lifestyles. Beyond the methodology, the attention to detail and the support system she sets up are exceptional. She ensures the journey of nutritional improvement doesn't feel weary or lonely. Loved the gamification elements which made the process fun while encouraging a focus on sustainable, long-term habits. Would definitely recommend!!

 Trustindex verifies that the original source of the review is Google.  When looking for someone to help you through your health journey, I think it is very important that the people who are guiding you do not approach it with any judgement. That is one of the best things I find about Avni & her team. They don't make food your enemy but rather teach you how to do it right, spending a lot of time in understanding your likes and dislikes and really personalising it to your need. You can be sure that you are being looked after individually. Alongside that, they also offer is a wealth of knowledge but also a delicate approach towards your journey. This is the main reason why I would recommend Avni to everyone.

 Trustindex verifies that the original source of the review is Google.  In March 2025, I had a scare with a sudden spike in my sugar levels. That was my wake-up call—I knew it was time to take my health seriously. I wasn’t looking for a quick fix but a long-term, sustainable lifestyle change. That’s when a close friend introduced me to Avni and NutriActivania. I reached out to Avni, and we discussed my goals and what I hoped to achieve. She and her team immediately put together a plan tailored specifically for me. The best part was how flexible it was—no drastic cuts, no extreme measures. Instead, they focused on equipping me with the skills and habits I needed to make lasting lifestyle changes. They listened to what worked for me, especially in terms of food preferences, and built a plan around my life rather than expecting me to adjust to theirs. That level of customization is what made it easy for me to stay committed. Each week, they share a personalised food plan and always check in before finalizing it. Avni has been incredibly supportive—always available to answer questions and consistently encouraging me to stay on track. Over the last seven months, I have lost 9 kgs. My sugar levels are back to normal, my cholesterol has dropped, and most importantly, I feel healthier. I eat better, and I am far more mindful about what I consume. I truly believe they’ve given me the tools to make better choices and have been instrumental in helping me reshape my lifestyle. Thank you, Avni and team. Thank you for being part of my journey and for helping shape it in the best way possible.

 Trustindex verifies that the original source of the review is Google.  During my first pregnancy, I was worried because I didn’t know how to give proper nutrition to my baby. Someone suggested Nutritionist Avni Kaul, so I joined her program and followed her diet plan throughout my pregnancy. She gave me a healthy meal plan that also allowed me to enjoy the foods I liked. My baby girl was born healthy and at a good weight. After pregnancy, I struggled with my weight, so I joined Avni Kaul’s post-pregnancy weight loss program. My weight went from 65 kg to 56 kg. I truly thank Nutri Activania and Nutritionist Avni Kaul for their support and guidance during my pregnancy and weight loss journey.
