How to Measure for the Army Tape Test
Men are taped at the neck and waist; women at the neck, waist, and hips. Placement accuracy drives the result.
At a glance
What Gets Measured
The Army tape test uses circumference measurements instead of a scale. Men are measured at the neck and the waist. Women are measured at the neck, waist, and hips. Those numbers, together with height, feed a logarithmic formula that estimates body fat percentage.

Results
Tape Placement
- Neck: just below the larynx (Adam's apple), tape level and perpendicular to the neck's long axis.
- Waist (men): horizontally around the abdomen at the level of the navel.
- Waist (women): at the narrowest point of the abdomen, usually above the navel.
- Hips (women only): around the widest point of the hips and buttocks, tape horizontal.
Technique That Keeps It Fair
Keep the tape snug against the skin without compressing it, measure at the end of a normal exhale, and read to the nearest half inch. Official procedure takes multiple measurements at each site and averages them, so a single sloppy reading does not decide the outcome.
Why the Formula Cares About Your Neck
The estimate is driven by the difference between waist and neck (for women, waist plus hip minus neck). A larger neck reading lowers the estimate, because neck size correlates with lean mass. Never inflate the neck measurement deliberately — that is falsifying an official test.
Frequently Asked Questions
Should I suck in my stomach during the tape test?
No. Stand relaxed and measure at the end of a normal exhale. Sucking in or flexing changes the reading and is against procedure.
How many times is each site measured?
Official procedure calls for a series of measurements at each site, averaged together, to reduce error. Self-testing with this calculator benefits from the same approach.
Does the tape test use inches or centimeters?
The official Army procedure uses inches, rounded to the nearest half inch. This calculator accepts both metric and imperial units.
Can I do the tape test on myself?
You can estimate with a helper or a mirror, but self-measurement is less accurate. Official testing must be performed by trained personnel.
