Body Fat Measurement Methods Compared
Several methods exist for estimating body fat, each with different tradeoffs between accuracy, cost, and convenience.
DEXA scan
Considered the gold standard for accuracy, but requires a specialized facility and a cost per scan, making frequent testing impractical for most people.
Skinfold calipers
Affordable and reasonably accurate when done consistently by the same person at the same sites, though technique-dependent.
Smart scales (bioelectrical impedance)
Convenient for daily tracking but can be affected by hydration levels, making trends more reliable than any single reading.
Navy method (tape measurements)
Free and reasonably accurate for tracking trends, using simple tape measurements and a standard formula.
Body fat calipers
An accessible way to track body fat consistently.
