In less than 30 seconds and with only two photos, calculate more than ten measurements with impressive accuracy!
How accurate are the measurements?
Reproducibility
We measured each participant twice, with Hexfit Lab and with the help of experts.
The repeatability analysis shows the difference (in cm) between two measurement sessions.
Lower values in each measurement mean a more consistent result.
Circumference | Neck | Hip | Thigh | Arm | Waist | ... |
Hexfit Lab | 0.07 | 0.51 | 0.46 | 0.21 | 0.94 |
|
Expert average | 0.56 | 0.86 | 0.69 | 0.59 | 1.31 |
|
Conclusion:
Hexfit Lab proves to be better in terms of repeatability. With the lowest value difference of 0.07 cm, the highest of 0.94 cm, and an average of 0.4 cm.
Hexfit Lab therefore demonstrates greater consistency in measurements. |
Accuracy
The accuracy analysis shows the difference between manual measurements by an expert and Hexfit Lab measurements.
Lower values (cm) mean greater accuracy.
Circumference | Neck | Hip | Thigh | Arm | Waist | ... |
Hexfit Lab | 2.09 | 3.20 | 2.56 | 1.33 | 3.20 |
|
Expert average | 1.19 | 1.61 | 0.81 | 0.82 | 1.61 |
|
*We used the average measurements from 3D scanners as a reference, as they are more accurate than experts.
Conclusion:
The value calculated by Hexfit Lab is on average 0.98 cm less accurate than that of an expert. Greater accuracy by humans was to be expected, however the repeatability of the results will allow us to see the same delta in the client's morphological change without any problems.
Note that human measurements were taken by experts. If you ask your clients to take their own measurements, the discrepancies will be much greater. Hexfit Lab's accuracy should be higher at that point.
In short, the decision is yours. It's up to you to decide how much time you want to invest in testing and the level of accuracy required for your needs. |
