Wondering what your ideal body weight actually is — not a number from a magazine, but a genuine healthy range based on your height and body type? This ideal weight calculator gives you that number in seconds, based on three separate scientific formulas averaged together for the most balanced result possible.
Whether your goal is weight loss, muscle gain, or simply knowing where you stand — this is the number to aim for.
What your range means:
Your ideal weight is not a single fixed number — it is a healthy range your body can comfortably sit within. Anywhere inside this range is considered healthy for your height and gender. The midpoint is simply the average of three leading scientific formulas. Use this as a target, not a rigid rule.
What is ideal body weight — and how is it different from BMI?
Most people have heard of BMI as a way to measure whether their weight is healthy. And while BMI has its uses, it has one significant limitation — it treats every person of the same height as identical, regardless of their muscle mass, bone density, or body composition.
Ideal body weight works differently. It gives you a weight range based specifically on your height and gender — a range that accounts for natural variation in body structure without penalising people who carry more muscle than average.
That does not mean ideal weight is a perfect science. No single number can capture every individual’s unique body. But as a practical target for most people — something to aim toward during a weight loss or fitness journey — a calculated ideal weight range is far more useful than a vague feeling of where you should be.
The range this calculator gives you is the sweet spot where research consistently shows most people of your height feel and function well.
How this ideal weight calculator works
Rather than relying on a single formula, this calculator uses three separate scientific methods and averages them together. This approach gives a more balanced result than any single formula alone.
The three formulas are the Devine formula, the Robinson formula, and the Miller formula — all established references in clinical nutrition and medical settings.
Each formula approaches ideal weight slightly differently based on the research data it was built on. Averaging the three smooths out the differences and gives you a midpoint that reflects the general scientific consensus rather than any single study’s conclusions.
The result you see is your midpoint ideal weight in kg, along with a healthy range of plus or minus 10 percent around it — because healthy bodies at the same height genuinely do vary, and a range is more honest than a single fixed number.
How to use this ideal weight calculator
Height
Enter your height in centimeters. If you know your height in feet and inches, multiply your feet by 30.48 and add your inches multiplied by 2.54.
Example: 5 feet 4 inches = (5 × 30.48) + (4 × 2.54) = 152.4 + 10.16 = 162.56 cm.
Gender
Select male or female. The formulas use different constants for men and women because average skeletal frame size and muscle mass distribution differ between the sexes.
Reading your result
Your result shows three numbers — your lower range, your midpoint, and your upper range. All three are considered healthy for your height.
If your current weight is above your upper range, losing weight toward the midpoint is a reasonable goal. If you are within the range already, maintaining or improving body composition is the more relevant focus than changing the number on the scale.
Ideal weight for average Filipino men and women
To give you a real-world reference before you calculate your own number, here are ideal weight ranges based on typical Filipino heights.
Average Filipino male height is approximately 162 cm:
Ideal weight range — 55 kg to 68 kg
Midpoint — approximately 61 kg
Average Filipino female height is approximately 152 cm:
Ideal weight range — 44 kg to 54 kg
Midpoint — approximately 49 kg
If your current weight is above these ranges and your height is close to the Filipino average, our Calorie Deficit Calculator can help you build a plan to move toward your ideal weight at a safe, sustainable pace.
What if my ideal weight feels unrealistic right now?
This is one of the most common reactions people have when they first see their ideal weight range — and it is completely understandable.
If you are significantly above your range right now, the number can feel distant or discouraging. The most useful way to reframe it is to stop treating ideal weight as a destination you need to reach by a certain date, and start treating it as a direction to move in.
Losing even five to ten percent of your current body weight produces measurable health benefits — improved blood pressure, better blood sugar control, reduced joint strain — regardless of whether you have reached your ideal weight range yet. Progress matters far more than perfection.
Set your ideal weight as a long-term reference point. Use your calorie deficit target as your daily action step. And measure success by the direction you are moving, not only by whether you have arrived.
Ideal weight versus goal weight — which should you use?
These two numbers serve different purposes and it helps to know the difference.
Your ideal weight is a scientifically calculated range based on your height and gender. It does not change based on how you feel about your body or what size clothing you want to wear.
Your goal weight is personal. It is the number you decide to aim for based on your own health goals, fitness level, and what feels right for your body. Your goal weight might land inside your ideal weight range, below it, or slightly above it depending on how much muscle you carry.
The ideal weight range is a useful anchor — a reference point grounded in research. Your goal weight is the personal target you build your plan around. Both have their place, and neither one overrides the other.
Frequently asked questions
How accurate is an ideal weight calculator?
Ideal weight calculators give you a research-based estimate, not a medical measurement. The formulas this calculator uses were developed from population data and are widely referenced in clinical settings — but they cannot account for individual factors like muscle mass, bone density, or body composition.
Use the result as a practical guideline and a direction to work toward, rather than a precise target that must be hit exactly.
What is the ideal weight for my height in kg?
Your ideal weight in kg depends on both your height and your gender. Use the calculator above — enter your height in centimeters and select your gender for your personal result.
For reference: an average Filipino male at 162 cm has an ideal weight range of roughly 55 to 68 kg. An average Filipino female at 152 cm has an ideal weight range of roughly 44 to 54 kg.
Is ideal weight the same as healthy weight?
They are closely related but not exactly the same. Ideal weight refers to the calculated range based on height and gender formulas. Healthy weight is a broader concept that also considers factors like blood pressure, blood sugar, cholesterol, and overall metabolic health.
You can be within your ideal weight range and still have health issues — or slightly outside it and be metabolically healthy. The number on the scale is one signal among many, not the whole picture.
What if I am muscular — will my ideal weight be wrong?
Yes — this is the main limitation of all ideal weight formulas. They were built on average body composition data and do not distinguish between muscle and fat.
If you carry significantly more muscle than average — through years of strength training, for example — your actual healthy weight will likely be higher than what the calculator suggests. In this case, body fat percentage is a more relevant measure than ideal weight.
How long will it take to reach my ideal weight?
Divide the difference between your current weight and your ideal weight midpoint by your chosen weekly loss rate.
Example: if you are 75 kg and your ideal weight midpoint is 61 kg, that is 14 kg to lose. At 0.5 kg per week, that is 28 weeks — roughly seven months.
Use our Calorie Deficit Calculator to build a daily calorie target that moves you toward that goal at a pace that works for your lifestyle.
Should I aim for the midpoint or the top of my range?
Either is a valid target depending on your starting point and your goals.
If you are well above your range, aiming for the upper end first is more realistic and gives you an early win to build on. Once there, you can reassess whether going further feels right for your body.
If you are just above your range or at the top of it already, the midpoint is a reasonable next target — especially if your goal involves improving body composition rather than just losing weight.
