Wireframe Mode

Wireframe of a director's chair and megaphone

Use the extended parameters for the wireframe effect to set the size of the wire and specify the measurement in pixels or units.

When you use pixels, the thickness of the wire is based on the screen pixels. Therefore, it's absolute, and remains the same, regardless of its distance from the camera. If you use units, the thickness is based on world units, and varies depending on the distance from the camera.

It's easier to compare the effect of pixels and units if you first adjust the camera view to give a greater sense of distance. You can most easily do this with the Perspective viewport navigation tool, which dollies the camera in one direction, while changing the field of view in the other.
