Current Army body composition screening
Although many people still search for an Army body fat calculator or military BMI calculator, the Army's July 2026 public guidance says its current body-composition assessment uses waist-to-height ratio (WHtR), replacing the previous height-and-weight tables, circumference-based tape test, and supplemental body-fat assessments. This page calculates that ratio; it does not estimate body-fat percentage.
Formula and example
WHtR = waist circumference at the navel (inches) / height (inches)
For a 38-inch waist and 70-inch height, 38 / 70 = 0.543 when rounded to three decimals. The Army's published numeric benchmark is below 0.55. A result at or above 0.55 reaches the confirmation-test threshold described in the Army's public update.
How to measure
Use the waist circumference measured at the navel (belly button) and height in inches so both inputs use the same unit. This calculator only performs the ratio arithmetic from values you enter; it cannot verify measurement technique or determine an official personnel outcome.
WHtR is not BMI or body-fat percentage
BMI uses weight and height. Body-fat percentage estimates the share of body mass that is fat. WHtR divides waist circumference by height. They are different measurements, so an old BMI-based estimate should not be treated as an Army body-composition result.

Frequently asked questions
What does this Army body-fat calculator calculate?
It calculates waist-to-height ratio, the current Army body-composition screening measure described in the July 2026 update. It does not calculate body-fat percentage.
What is the Army WHtR benchmark?
The Army's published benchmark is a ratio below 0.55. The public update says results of 0.55 or higher receive a confirmation test; this tool is not an official assessment.
Does the current Army standard use BMI?
The Army's July 2026 update says WHtR replaces the previous height-and-weight tables and body-fat assessment methods. BMI is a separate calculation and is not calculated here.
Can I use centimeters?
Convert both measurements to the same unit before dividing. The Army's published implementation describes recording waist and height in inches, so this calculator accepts inches.
