Educational estimate only. Individual error can be larger, and results vary with lighting, pose, clothing, camera angle, and model behavior. This is not a medical device.

MORE THAN A NUMBER
See what changed.
Know what to do next.
A body fat estimate matters most as a consistent baseline. AI Body Fat Calculator connects your range, muscle balance, and next actions so future check-ins have context.

A directional estimate with confidence bounds—not false precision.
Muscle balance
Visual scoring across six major muscle groups highlights strengths and gaps.
Repeatable progress
Save a numeric baseline, repeat under similar conditions, and focus on the trend rather than one scan.

CHOOSE THE RIGHT MEASURE
Fast direction or clinical detail?
Instant & accessible
DirectionalBest for a quick baseline and repeated visual check-ins under consistent photo conditions. Individual error can be larger.
Technique dependent
RepeatableUseful when the same trained person measures the same sites with a consistent protocol.
Clinical detail
High precisionUseful for detailed professional body-composition assessment, while still subject to device, protocol, and between-method differences.
QUESTIONS, ANSWERED
The honest answers.
Body composition is nuanced. Here is what to know before you scan.
How accurate is AI body fat estimation?+
AI photo analysis is best used as a directional estimate, not a diagnosis. Your result includes a confidence range because lighting, pose, clothing and photo angle all affect visual estimates.
AI body fat calculator vs DEXA scan?+
DEXA is a clinical measurement and remains the more precise option. Our calculator is a fast, accessible way to get a baseline and track visual progress between formal measurements.
How do I take the best photo?+
Stand relaxed against a plain background in even lighting. Keep your full body in frame, face the camera, and wear fitted clothing. Avoid flexing, filters and dramatic shadows.
Is it really free?+
Yes. You can run up to three complimentary scans per day with no account required. Your photo is sent to our AI processor only for the requested analysis and is not stored by AI Body Fat Calculator.
