Guidelines for Choosing Coordinate Units

It is good practice to set the coordinate units before designing the application interface and placing objects onto canvases. When choosing coordinate units, consider the runtime platforms on which the application will be deployed.

If you deploy your application only on GUI platforms, such as Microsoft Windows, the choice of coordinate system is a matter of personal preference. If you deploy your application across multiple GUI platforms, or on the same platform but with different screen sizes or resolutions, pixels should not be used as the coordinate unit.
