Can I compare InBody 120 and 970 results directly?
Only carefully. The models can differ in measurement setup and outputs. For trend, use the same model whenever possible.

InBody 120, 270S, 380 vs 970/970S: why the device model changes the result
The device model changes the result because basic InBody lines (120, 270S, 380) measure fewer frequencies and fewer body segments than the advanced 970/970S line, giving fewer layers of information. Different InBody models are not just different-looking scales: they can differ in measurement setup, frequencies, outputs and the amount of context they provide. That is why results from one model should not be casually compared with results from another as if they were identical.
Why model differences matter
Body composition devices differ in electrodes, measurement paths, frequencies, algorithms and output detail. Even within one brand, a higher model can provide more information and a different practical reading experience.
This does not mean lower models are useless. It means that trend is clearest when you compare repeated measurements on the same type of device.
If the model changes, treat the new measurement as a new baseline rather than a perfect continuation of the old series.
What 970/970S adds in practice
The value of InBody 970/970S is not just more numbers. It is a richer context: muscle, fat, water, segmental outputs, phase angle, visceral context and history can be read together.
For a visitor, that means the result can answer better questions: is change mostly fat, muscle or water? Are segments balanced? Does the water picture explain the surprise?
The result is still bioimpedance, so preparation and repeated trend matter.
Why results from different models may not match
A home scale, a simpler InBody model and a premium model do not have to show the same body fat, muscle or water values. Different measurement paths and algorithms can shift estimates.
The practical mistake is comparing one old result from one device with a new result from another device and calling the difference progress or failure.
If you switch models, use the first new result as a reference point and follow the next trend on the same setup.

FAQ
Frequently asked questions
Does a higher model mean the result is a diagnosis?
No. A higher model can provide richer context, but it is still body composition measurement, not a medical diagnosis.
What is the biggest practical reason to choose a higher model?
Better context: muscle, fat, water, segments, phase angle, visceral context and history can be read together.
Want more than body fat percentage?
InBody 970 / 970S is most useful when you want to read results in context: muscle, fat, water, segments, phase angle, visceral context and your own trend over time.
