A Body Shape Index, usually shortened to ABSI, is a body-size metric designed to capture something that body mass index misses: how much abdominal size a person carries relative to height and weight. BMI is widely used because it is quick, but it does not describe where fat is distributed. That matters because central fat around the waist is linked more strongly to metabolic and cardiovascular risk than weight alone. ABSI was introduced by researchers Jesse Krakauer and Nir Krakauer in 2012 as a way to standardize waist circumference against BMI and height. In practical terms, the calculator combines waist measurement, height, and weight into one number that can be compared with population norms or interpreted as a z score. Researchers and clinicians use it more as a risk-stratification aid than as a stand-alone diagnosis. In plain language, a higher ABSI suggests the waist is larger than expected for a person's height and weight, which may indicate higher central adiposity. That does not mean the index replaces medical evaluation. It is best used alongside BMI, waist circumference, blood pressure, lipid tests, glucose data, and personal history. A calculator is helpful because the formula is not something most people want to compute by hand, especially when unit conversion is involved. It gives a quick way to see whether two people with the same BMI may still have different body-shape-related risk profiles because one carries more abdominal girth than the other.
ABSI = waist circumference / (BMI^(2/3) x height^(1/2)), where waist circumference and height are measured in metres and BMI = weight(kg) / height(m)^2. Worked example: weight 73.5 kg and height 1.75 m give BMI = 73.5 / 1.75^2 = 24.0. If waist circumference is 0.85 m, then BMI^(2/3) is about 8.32 and height^(1/2) is about 1.323. ABSI = 0.85 / (8.32 x 1.323) = about 0.077.
- 1Measure your waist circumference at the standard location recommended by your clinician or measurement protocol, then record it in centimetres or metres.
- 2Enter your height and weight so the calculator can determine your body mass index first.
- 3The calculator converts units if needed and applies the ABSI formula that scales waist size relative to BMI and height.
- 4Review the resulting ABSI value and, if available, compare it with age- and sex-specific norms or z-score interpretations.
- 5Use the number as one screening input alongside BMI, waist circumference, blood pressure, and other health markers rather than treating it as a diagnosis.
- 6If your result seems high or changes significantly over time, discuss it with a healthcare professional who can interpret it in context.
Lower than many simplified web examples
This profile shows how ABSI can remain moderate even when BMI is normal, as long as waist circumference is not disproportionately high. The value becomes more useful when compared with norms.
Higher central adiposity signal
BMI alone would not distinguish this person from the previous example. ABSI rises because the waist is larger relative to body size.
Illustrates unit-sensitive calculation
This example shows why a calculator is useful: BMI and ABSI both depend on unit consistency. A small measuring error in waist circumference changes the result noticeably.
Lower waist-related risk signal
Two adults can have nearly identical BMIs but very different waist distribution. ABSI helps highlight that difference.

ABSI is not validated as a stand-alone screening tool for children in the same
ABSI is not validated as a stand-alone screening tool for children in the same simple way it is used in adult research, so pediatric interpretation should rely on age-specific clinical guidance. When encountering this scenario in a body shape index calculations, users should verify that their input values fall within the expected range for the formula to produce meaningful results. Out-of-range inputs can lead to mathematically valid but practically meaningless outputs that do not reflect real-world conditions.
People with unusual body composition, such as very high muscle mass, pregnancy,
People with unusual body composition, such as very high muscle mass, pregnancy, or abdominal medical conditions, may get results that need clinical interpretation rather than simple risk labeling. This edge case frequently arises in professional applications of a body shape index where boundary conditions or extreme values are involved. Practitioners should document when this situation occurs and consider whether alternative calculation methods or adjustment factors are more appropriate for their specific use case.
Negative input values may or may not be valid for a body shape index depending on the domain context.
Some formulas accept negative numbers (e.g., temperatures, rates of change), while others require strictly positive inputs. Users should check whether their specific scenario permits negative values before relying on the output.

What is A Body Shape Index?
ABSI is a metric that adjusts waist circumference for height and BMI. It was developed to capture central body shape, which BMI alone does not describe well. In practice, this concept is central to a body shape index because it determines the core relationship between the input variables. Understanding this helps users interpret results more accurately and apply them to real-world scenarios in their specific context.
How do you calculate ABSI?
First calculate BMI from height and weight, then divide waist circumference by BMI raised to the two-thirds power and height raised to the one-half power. A calculator is useful because unit consistency matters. The process involves applying the underlying formula systematically to the given inputs. Each variable in the calculation contributes to the final result, and understanding their individual roles helps ensure accurate application.
What is a normal ABSI value?
There is no single universal cutoff that applies equally to every age and sex group. ABSI is usually interpreted relative to population norms, percentiles, or z scores rather than a single fixed threshold. In practice, this concept is central to a body shape index because it determines the core relationship between the input variables. Understanding this helps users interpret results more accurately and apply them to real-world scenarios in their specific context.
How is ABSI different from BMI?
BMI tells you weight relative to height, but it does not show where fat is carried. ABSI adds waist size, so it is more sensitive to abdominal adiposity. The process involves applying the underlying formula systematically to the given inputs. Each variable in the calculation contributes to the final result, and understanding their individual roles helps ensure accurate application. Most professionals in the field follow a step-by-step approach, verifying intermediate results before arriving at the final answer.
What are the limitations of ABSI?
ABSI depends heavily on accurate waist measurement and is less familiar to the general public than BMI. It is better used as a supplementary risk marker than as a diagnosis by itself. This is an important consideration when working with a body shape index calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied.
Who invented ABSI?
The index was introduced by researchers Jesse Krakauer and Nir Krakauer in 2012. Their work focused on improving risk prediction beyond BMI alone. This is an important consideration when working with a body shape index calculations in practical applications. The answer depends on the specific input values and the context in which the calculation is being applied. For best results, users should consider their specific requirements and validate the output against known benchmarks or professional standards.
How often should you recalculate ABSI?
It makes sense to recalculate when your waist size, weight, or body-composition pattern changes. People tracking health progress often recheck it alongside BMI and waist circumference every few months. The process involves applying the underlying formula systematically to the given inputs. Each variable in the calculation contributes to the final result, and understanding their individual roles helps ensure accurate application.
