This table shows your BMI (Body Mass Index) for a range of weights based on your height, age, and sex. Your BMI' (BMI Prime) is also shown.

Your BMI is used to estimate the average human body composition of BFP (Body Fat Percentage) versus LBM (Lean Body Mass).

The body composition is used to estimate caloric maintenance requirements. First we estimate the BMR (Basal Metabolic Rate), and then TDEE (Total Daily Energy Expenditure) for various activity levels.

Enter your height (in meters), your age, and your sex. Then click 'Update Table'.

In the Table options section you can customize the weight ranges used in the table, and the increment between weights.

^topThe body mass index (BMI) or Quetelet index is a value derived from the mass (weight) and height of an individual. The BMI is defined as the body mass divided by the square of the body height, and is universally expressed in units of kg/m2, resulting from mass in kilograms and height in metres.

The BMI is an attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, and then categorize that person as underweight, normal weight, overweight, or obese based on that value. That categorization is the subject of some debate about where on the BMI scale the dividing lines between categories should be placed.

Commonly accepted BMI ranges are:

- underweight: under 18.5 kg/m2
- normal weight: 18.5 to 25
- overweight: 25 to 30
- obese: over 30

BMIs under 20.0 and over 25.0 have been associated with higher all-cause mortality,
increasing risk with distance from the 20.0-25.0 range.
The prevalence of overweight and obesity is the highest in the Americas and lowest in South East Asia.
The prevalence of overweight and obesity in high income and upper middle income countries is more
than double that of low and lower middle income countries.

BMI Prime, a modification of the BMI system, is the ratio of actual BMI to upper limit optimal BMI (currently defined at 25 kg/m2), i.e., the actual BMI expressed as a proportion of upper limit optimal. The ratio of actual body weight to body weight for upper limit optimal BMI (25 kg/m2) is equal to BMI Prime. BMI Prime is a dimensionless number independent of units. Individuals with BMI Prime less than 0.74 are underweight; those with between 0.74 and 1.00 have optimal weight; and those at 1.00 or greater are overweight. BMI Prime is useful clinically because it shows by what ratio (e.g. 1.36) or percentage (e.g. 136%, or 36% above) a person deviates from the maximum optimal BMI.

For instance, a person with BMI 34 kg/m2 has a BMI Prime of 34/25 = 1.36, and is 36% over their
upper mass limit. In South East Asian and South Chinese populations,
BMI Prime should be calculated using an upper limit BMI of 23 in the denominator instead of 25.
BMI Prime allows easy comparison between populations whose upper-limit optimal BMI values differ.

The body fat percentage (BFP) of a human or other living being is the total mass of fat divided by total body mass, multiplied by 100; body fat includes essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions. The percentage of essential body fat for women is greater than that for men, due to the demands of childbearing and other hormonal functions. Storage body fat consists of fat accumulation in adipose tissue, part of which protects internal organs in the chest and abdomen. The minimum recommended total body fat percentage exceeds the essential fat percentage value reported above. A number of methods are available for determining body fat percentage, such as measurement with calipers or through the use of bioelectrical impedance analysis.

The body fat percentage is a measure of fitness level, since it is the only body measurement
which directly calculates a person's relative body composition without regard to height or weight.
The widely used body mass index (BMI) provides a measure that allows the comparison of the
adiposity of individuals of different heights and weights. While BMI largely increases as
adiposity increases, due to differences in body composition, other indicators of body fat
give more accurate results; for example, individuals with greater muscle mass or larger
bones will have higher BMIs. As such, BMI is a useful indicator of overall fitness for a
large group of people, but a poor tool for determining the health of an individual.

Lean body mass (LBM) is a component of body composition, calculated by subtracting body fat weight from total body weight: total body weight is lean plus fat.

The percentage of total body mass that is lean is usually not quoted – it would typically be 60–90%.
Instead, the body fat percentage, which is the complement, is computed, and is typically 10–40%.
The lean body mass (LBM) has been described as an index superior to total body weight for
prescribing proper levels of medications and for assessing metabolic disorders, as body fat
is less relevant for metabolism. LBW is used by anesthesiologists to dose certain medications.

Basal metabolic rate (BMR) is the rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(h·kg). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food).

Metabolism comprises the processes that the body needs to function.
Basal metabolic rate is the amount of energy per unit time that a person needs to keep the
body functioning at rest. Some of those processes are breathing, blood circulation,
controlling body temperature, cell growth, brain and nerve function, and contraction of
muscles. Basal metabolic rate (BMR) affects the rate that a person burns calories and
ultimately whether that individual maintains, gains, or loses weight. The basal
metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by
individuals. It is influenced by several factors. BMR typically declines by 1–2%
per decade after age 20, mostly due to loss of fat-free mass, although the
variability between individuals is high.
