Standardizing Measurements between computers

We are working on a project in which we need to measure the distances on certain pictures between computers. Is there anyway IMAGEJ can help standardize the picture sizes as well as the pixels measurements between computers that have different size screens? Thank you!

The picture size is independent on the size of your screen, if you hover the mouse on the icon of the picture file on windows you should see an info message with the dimensions in pixels.
Therefore the same file on different computer will still have the same dimensions, whatever the software used.
Does it answer the question ? :thinking:
