"What's a healthy weight for my height?" is one of the most common health questions people search for — and the honest answer is a range, not a single target number, calculated using the same BMI formula covered throughout this blog.
How a healthy weight range is calculated
A healthy weight range for a given height is simply the weight span that produces a BMI between 18.5 and 24.9 — the "healthy weight" category described in our BMI categories guide. You can find your own exact range by testing values in our free BMI calculator until the result lands at the top and bottom of that range.
Example healthy weight ranges (metric)
| Height | Healthy weight range (BMI 18.5–24.9) |
|---|---|
| 1.55 m (5'1") | 44 – 60 kg |
| 1.60 m (5'3") | 47 – 64 kg |
| 1.65 m (5'5") | 50 – 68 kg |
| 1.70 m (5'7") | 53 – 72 kg |
| 1.75 m (5'9") | 57 – 76 kg |
| 1.80 m (5'11") | 60 – 81 kg |
| 1.85 m (6'1") | 63 – 85 kg |
Notice how wide each range is — typically 15-20 kg between the low and high end. That's an important detail people often miss: there is no single "correct" weight for a given height, only a broad healthy range within which individual factors (build, muscle mass, personal history) reasonably determine where someone falls.
Why the range is so wide
Two people can be the exact same height with very different, equally healthy body types — a naturally leaner frame versus a naturally broader, more muscular one. The healthy weight range reflects this real variation rather than pointing to one "ideal" number. Fixating on the exact midpoint of the range, rather than the range as a whole, is a common and unnecessary source of frustration.
What this range doesn't account for
As with BMI generally, these ranges don't distinguish muscle from fat (see our athletes guide) and don't reflect individual factors like frame size, age, or ethnicity-specific risk research. Someone with a naturally larger bone structure or significant muscle mass may sit comfortably above the calculated range while still being in excellent health.
Using this information constructively
Rather than treating the top or bottom of your range as a rigid target, use it as general orientation: if your current weight sits well outside the range for your height, it's a reasonable prompt to look more closely at your habits or check in with a healthcare provider. If you're comfortably within the range, small day-to-day weight fluctuations aren't something to stress over.
Where to go next
Once you know your range, our guides on setting a realistic weight goal and building sustainable habits cover how to approach change constructively, without falling into the all-or-nothing thinking that derails most quick-fix attempts.
This article is educational and general in nature. For guidance specific to your body and health history, consult a doctor or registered dietitian.
Work through a height example
For a height of 1.70 m, the lower adult BMI category boundary corresponds to 18.5 × 2.89 = 53.465 kg. The upper boundary is below 25 × 2.89 = 72.25 kg. This arithmetic describes a screening category, not a recommended personal goal of 53 or 72 kg. Rounding a table can obscure the exact boundary. Pregnancy, illness, muscle mass, recent weight changes and medical history can all affect how a clinician interprets the range. Avoid turning the lowest value into a dieting target.
