Overview
The InBody H40 is a body composition scale that reads weight to 0.1 lb accuracy and supports up to 330 lb, using electrical (bioelectrical impedance) measurement. It runs on AA batteries and has a black finish over a glass, metal, plastic and synthetic leather build.
InBody is a name associated with bioelectrical impedance analysis, and the H40's measurement type field confirms it works on that same principle rather than being a plain weight-only scale. At 6.2 lb it's noticeably heavier than a basic bathroom scale, which tracks with a glass platform and internal electronics.

Who it's for
People who want to track more than weight alone at home, using a scale built around bioelectrical impedance. Not for anyone who just wants a lightweight, weight-only scale.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reads to 0.1 lb accuracy
- Supports up to 330 lb capacity
- Runs on standard AA batteries
- Unit itself weighs a hefty 6.2 lb
- No seller description or reviews included
- Exact composition metrics shown aren't detailed
Performance notes
Bioelectrical impedance scales send a low current through the body via footpads to estimate composition, using body weight as one input. The listing confirms 0.1 lb weight accuracy and a 330 lb capacity but doesn't break out which composition metrics (body fat, muscle mass, water) are displayed.
