BMI Chart for Adults by Height and Weight — Full Reference Table

BMI (Body Mass Index) gives you a quick number that places your height and weight into a standard category. It's not perfect — it doesn't account for muscle mass, body composition, or where you carry fat — but it's a useful starting point for understanding weight relative to height.

Use the BMI Calculator for an instant result, or use the reference tables below to find where you fall without any calculation.

How BMI Is Calculated

The formula is simple:

BMI = weight in kg ÷ (height in meters)²

For imperial units: BMI = (weight in lbs × 703) ÷ (height in inches)²

Example: A person who is 175 cm (1.75 m) tall and weighs 75 kg: BMI = 75 ÷ (1.75)² = 75 ÷ 3.0625 = 24.5

That falls in the "normal weight" range.

BMI Categories (WHO Standard)

Category	BMI Range
Underweight (severe)	Below 16
Underweight (moderate)	16.0–16.9
Underweight (mild)	17.0–18.4
Normal weight	18.5–24.9
Overweight	25.0–29.9
Obese (Class I)	30.0–34.9
Obese (Class II)	35.0–39.9
Obese (Class III)	40.0 and above

The "normal weight" range of 18.5–24.9 is the standard target for adults, though research suggests that for Asian populations, health risks increase at lower BMI values (some guidelines use 23 as the overweight threshold for Asian adults).

BMI Chart: Metric (kg and cm)

The table below shows BMI values for common height and weight combinations. Values in the normal range (18.5–24.9) are in plain text; overweight (25–29.9) is marked with an asterisk; obese (30+) is marked with two asterisks.

What Your BMI Number Means in Practice

18.5–24.9 (Normal weight): Associated with the lowest risk of weight-related health problems. This is a range, not a single target. A BMI of 22 and a BMI of 24 are both "normal" — neither is meaningfully healthier than the other.

25–29.9 (Overweight): Slightly increased risk of cardiovascular disease, type 2 diabetes, and hypertension compared to the normal range. At the low end (BMI 25–27), the risk increase is modest. The risk rises more meaningfully toward the upper end of this range.

30+ (Obese): Progressively higher risk of serious health conditions including heart disease, stroke, type 2 diabetes, and certain cancers. Class I obesity (30–34.9) carries meaningfully higher risk than overweight; Class III (40+) carries significantly elevated risk across multiple conditions.

Below 18.5 (Underweight): Associated with its own health risks including nutritional deficiency, immune suppression, bone density loss, and in severe cases organ dysfunction. Being underweight is not safer than being in the overweight range.

Limitations of BMI for Adults

BMI is a population-level screening tool, not an individual health assessment.

Athletes and muscular individuals: Muscle is denser than fat. A highly muscular person can have a BMI in the "overweight" or "obese" range while having very low body fat and excellent health. NFL players, competitive powerlifters, and many rugby players fall into this category. For these individuals, body fat percentage — measured with the Body Fat Calculator — is more informative.

Older adults: As people age, they typically lose muscle mass and gain fat, but weight may stay the same. An older person with a "normal" BMI may have a high body fat percentage due to muscle loss. BMI tends to underestimate health risk in older populations.

Ethnic differences: Research shows that Asian populations have higher health risks at lower BMI values compared to European populations. Several Asian countries use 23 as the overweight threshold rather than 25, and 27.5 as the obese threshold rather than 30.

Pregnant women: BMI norms don't apply during pregnancy. Different guidelines apply for assessing healthy weight during pregnancy.

Height extremes: BMI is least reliable at very short heights (under 155 cm) and very tall heights (over 195 cm). At these extremes, the formula can produce misleading results relative to actual body composition.

What to Do If Your BMI Is Outside the Normal Range

A single BMI number is a starting point, not a verdict. The next steps depend on where you are:

If you're in the overweight range (25–29.9) with no other risk factors, focus on sustainable lifestyle habits — regular physical activity and a reasonable dietary pattern — rather than aggressive weight loss. Even modest improvements in fitness have significant health benefits independent of weight.

If you're in the obese range, it's worth discussing with a healthcare provider. A BMI above 30 qualifies for medical weight management support in many healthcare systems, and there are now more options than ever including medication, structured programs, and when appropriate, surgery.

If your BMI suggests underweight, particularly below 17.5, a healthcare provider can assess whether there's a nutritional, metabolic, or other underlying factor.
