It is sometime hard to have a first idea of how high to place an object in a 3D model on a production line.

Hopefully for you we are here to give you some guidelines!

The ISO 14738 standard provides us a easily calculable optimal hand zone, which limit the risk of MSD.

Above, you can see the optimal hand zone for à 50 percentile American male (medium size male).

Guideline

Ideally you want to design your workstation for a wild range of people. Here we will consider the 5 percentile  female and 95 percentile male to determine the optimal object location.

In the image above, we are using the ISO 14738 to determine the optimal hand zone. Indeed, the standard is explaining the object should be located between the hip and shoulder.

Using a rough measurement, we determined that the object should be located between 1 meter to 1.25 meter high in order limit the risk of MSD for the worker.

This is not enough!

This measures gives you an initial idea of how high to approximately place your objects, but this is not enough.

A better way to have a estimation of MSD risk is to use Ergonomic Workplace Design​​​​​​​ (EWD).
Thanks to EWD you'll be able to have an accurate worker posture evaluation in 3D.

Considering not only the object height but the manikin whole posture, the joint load considering extremely precise parameter like the task frequency, object weight, etc ...
