Healthy Weight by Height — What It Means and How It's Worked Out
Healthy weight by height refers to the range of body weights, at each height, that fall within the NHS BMI healthy category of 18.5 to 24.9. Rather than giving you one fixed number, this page shows both the full healthy weight range for your height and a single midpoint figure often used as an ideal weight by height reference — plus a complete chart covering every 2cm from 140cm to 210cm, so you can look up any height at a glance.
This differs slightly from our other weight tools by design. If you want a fully interactive comparison against your current weight, with ethnicity-adjusted thresholds, use our healthy weight range calculator. If you want a single sex-specific ideal weight figure using clinical formulas, see our ideal body weight calculator. This page's role in the silo is to be the definitive height-first lookup chart — enter your height once, and see both figures immediately, or scan the full table.
📋 Key Takeaways
✅Healthy weight by height = NHS BMI 18.5–24.9 rearranged around your exact height
🎯Ideal weight by height here means the midpoint of that range — a simple single reference figure
📊Full chart below covers 140cm to 210cm in 2cm steps for quick lookup
⚖️Any weight within your healthy range is equally acceptable — the midpoint is a reference, not a target
👶For adults 18+ only; children need NHS growth centile charts instead

The Formula Behind Healthy Weight by Height
Minimum healthy weight (kg) = 18.5 × height (m)² Maximum healthy weight (kg) = 24.9 × height (m)² Ideal weight by height (midpoint, kg) = 21.7 × height (m)² (approximate midpoint of the healthy range)
Worked Example
For an adult who is 172 cm tall (1.72 m), squaring the height gives 1.72 × 1.72 = 2.9584. Applying the boundaries:
Minimum healthy weight: 18.5 × 2.9584 = 54.7 kg
Maximum healthy weight: 24.9 × 2.9584 = 73.7 kg
Ideal weight by height (midpoint): 21.7 × 2.9584 = 64.2 kg
So for someone 172 cm tall, the full healthy weight range is roughly 54.7–73.7 kg, with 64.2 kg as a simple midpoint reference — not a strict target, just a useful single number when one is needed.

Interpreting Your Healthy Weight by Height Result
Your weight is inside the range: your BMI sits within the NHS healthy category for your height — no need to chase the exact midpoint figure.
Your weight is below the range: speak to your GP about safe weight gain. See our healthy weight gain guide.

Real-Life Example: Using the Chart to Set a Realistic Goal
Consider an adult who is 178 cm tall and currently weighs 92 kg. Looking up 178 cm in the full chart shows a healthy weight range of approximately 58.6–78.9 kg, with an ideal midpoint of around 68.7 kg. Rather than fixating on reaching exactly 68.7 kg, a more realistic first goal would simply be to move into the top of the healthy range — around 78.9 kg — which is a smaller, more achievable step.
This illustrates why the full range matters as much as the single "ideal" figure: it gives a realistic staged target rather than one distant number. For a personalised timeline to reach any point in the range, see our NHS weight loss calculator.
Expert Tips
Use the range, not just the midpoint, when setting weight goals — any point within it is healthy

Frequently Asked Questions — Healthy Weight by Height
A healthy weight by height chart shows the range of body weights considered healthy for each height, based on the NHS BMI band of 18.5 to 24.9. Rather than a single number, it typically shows a minimum and maximum weight for every height, since a healthy weight is a range rather than one fixed target.
How much you should weigh for your height depends on where you fall within the NHS healthy BMI range of 18.5 to 24.9. For example, at 170 cm, a healthy weight range is roughly 53.5 to 72.0 kg, with an ideal midpoint figure of around 62.7 kg. Use the calculator above for your exact height.
Healthy weight by height refers to a full range of weights, based on NHS BMI 18.5–24.9, that are all equally acceptable for a given height. Ideal weight by height usually refers to a single midpoint figure within that range, sometimes used as a simple reference point rather than a strict target.
The NHS healthy weight range itself, based on BMI 18.5–24.9, is applied the same way for men and women. However, some ideal weight formulas that give a single figure, such as the Devine formula, do use different constants for men and women — see our ideal body weight calculator for that approach.
Height-weight charts based on BMI give a reasonable population-level guide but do not account for individual differences such as muscle mass, bone density or body frame size. They are best used as a general reference point alongside other measures, not as a precise individual target.
If your weight falls outside the healthy weight by height range for your height, this may be worth discussing with your GP, particularly if combined with other health concerns. Being outside the chart range does not automatically mean there is a health problem, especially for very muscular or naturally lean individuals.
No. This healthy weight by height chart is designed for adults aged 18 and over. Children and teenagers need age- and sex-specific NHS UK-WHO growth centile charts rather than adult healthy weight by height figures — see our child growth chart calculator UK.
The healthy weight by height figures on this page are calculated directly from the NHS BMI healthy range of 18.5 to 24.9, using the standard BMI formula rearranged to solve for weight at each height. This approach is aligned with NHS Live Well and NICE guidance on healthy weight for UK adults.
Conclusion: Finding Your Healthy Weight by Height
Your healthy weight by height is best understood as a range rather than one fixed number — the free calculator and full chart above give you both your personal range and a simple ideal weight by height midpoint figure, plus the ability to see every height from 140cm to 210cm at a glance.
Remember that these figures are a population-level guide, not a clinical diagnosis. If your weight sits outside the healthy range, or if you have concerns, speak to your GP.
