How accurate is ShapeScale?Updated 10 days ago
In our March 2026 study, we compared ShapeScale with DXA scans in more than 1,000 adults. DXA is a clinical body composition scan.
- Body fat: ShapeScale was off by 1.89 percentage points on average. In the same study, a four-point bioelectrical impedance (BIA) scale, the InBody Dial H20, was off by 5.01 percentage points.
- Lean mass: ShapeScale was off by 1.49 kg (3.3 lb) on average, with an R² of 0.98.
