This calculator shows the height you would need to have at your current weight to achieve your target BMI. BMI is calculated as weight(kg) ÷ height(m)².

What Is a Reverse BMI Height Calculator?

💡 The Reverse BMI for Height Calculator helps you determine the height required to achieve your desired BMI, based on your current weight. Whether you’re trying to reverse-calculate a missing height value or explore how your weight relates to different BMI outcomes, this tool gives you fast and accurate results.

  • Estimating height when BMI and weight are known
  • Understanding how height affects BMI categories
  • Reverse-engineering fitness or health benchmarks

Simply enter your weight and desired BMI, choose your unit system, and the calculator will tell you what height that combination corresponds to.

Quick Questions

How Accurate Is the Reverse BMI Height Calculator?

 

Reverse BMI height estimates are based on the standard BMI formula applied in reverse. While BMI is a general guideline and doesn’t account for factors like muscle mass or body composition, the reverse calculation is mathematically sound.

To improve accuracy:

  • Use your most current weight

  • Use realistic BMI values (e.g. between 18.5 and 24.9)

  • Stick to one unit system (metric or imperial)

  • Remember BMI is a general estimate, not a medical diagnosis

What Is the Reverse BMI Formula for Height?

 

To calculate height from your weight and BMI, you can reverse the BMI formula:

Metric:
Height (m) = √(Weight (kg) ÷ BMI)

Imperial:
Height (in) = √((Weight (lbs) ÷ BMI) × 703)

This calculator applies those formulas automatically. It’s useful when you know your weight and want to find what height would correspond to a specific BMI.

About - Reverse BMI for Height

The Reverse BMI for Height Calculator estimates the height required to reach a specific BMI, using your current weight. By entering your weight and your target BMI, the tool works backwards using standard BMI formulas to calculate the corresponding height.

This tool is useful when you know your weight and want to determine what height corresponds to a target BMI. It can be used for setting realistic fitness goals, understanding BMI categories better, or exploring how your weight would relate to different height values.

  1. Choose your unit system (metric or imperial).

  2. Enter your current weight.

  3. Enter your desired BMI.

  4. Click the calculate button to see the estimated height that matches your inputs.

Use either kilograms (kg) and meters (m) for metric, or pounds (lbs) and inches (in) for imperial. Input a realistic BMI value—typically between 18.5 and 24.9 for a healthy range.

BMI = weight / height^2. To find height, the formula is reversed:

  • Metric: height (m) = √(weight (kg) ÷ BMI)

  • Imperial: height (in) = √((weight (lbs) × 703) ÷ BMI)

Your result is the height that corresponds to the BMI you entered, given your weight. It shows what height you would need to be to have that specific BMI. It’s a theoretical value and doesn’t suggest you should change your height—only how BMI scales.

Yes. If you know someone’s past weight and BMI (such as from a record), this calculator can help estimate what their height may have been at that time.

  • When analyzing past BMI records with missing height

  • For educational or research purposes

  • When trying to understand BMI ranges based on weight

  • Out of curiosity or for fitness-related experimentation

Stick with one unit system (either all metric or all imperial). Mixing units can lead to inaccurate results and confusion.

BMI is a general estimation tool. It doesn’t take into account muscle mass, body composition, or unique health conditions. Use it as a starting point, not a final word.

BMI was created in the 1830s by Belgian mathematician Adolphe Quetelet—long before modern fitness science. It was originally meant for population studies, not individual health.

Human height varies slightly throughout the day. You can be up to 1 inch taller in the morning than at night due to spinal decompression!

Questions - Reverse BMI for Height

This tool helps you calculate the height required to reach a specific BMI, based on your current weight. It’s ideal for back-calculating height when you already know your weight and target BMI.

Yes. If you have a desired BMI and know your weight, this calculator can estimate the height you would need to achieve that BMI.

The formula used is a rearranged version of the BMI equation:

  • Metric: Height (m) = √(Weight (kg) ÷ BMI)

  • Imperial: Height (in) = √((Weight (lbs) ÷ BMI) × 703)

People use it for educational purposes, fitness benchmarks, or to double-check recorded health data. It can also be helpful when reverse engineering values in health records or training apps.

It’s mathematically accurate but based on general BMI assumptions. It doesn’t account for muscle mass or body composition, so it’s a good estimate, not a medical assessment.

Yes. You can switch between units and the calculator will handle the correct formula automatically.

BMI is a broad guideline. It doesn’t measure body fat directly, but it’s still widely used to assess general health ranges and set goals.
