Choose based on the question, access and repeatability you need. A photo estimate can support everyday tracking; a clinical question needs an appropriate qualified professional and measurement method.
A range with context
Understand Body Fat Estimates
Choose a body-fat method for your purpose and interpret the result with its uncertainty intact.
Choose a method
Visual references are useful for orientation. A photo estimate interprets visible traits. A tape formula uses specific body measurements. Laboratory methods use different models and equipment. None of these outputs should be treated as interchangeable.

How the analysis works
Understand the method and what it cannot establish.
Why estimates change
Use same-input and changed-input examples before judging a new number.
Read a range, not a verdict
If two estimates overlap, a small numerical difference may not indicate a real change. Keep the method and conditions consistent and consider other evidence such as waist trends, training performance and repeated photos.
