<p>Almost all positions and sizes in GLFW are measured in screen coordinates relative to one of the two origins above. This includes cursor positions, window positions and sizes, window frame sizes, monitor positions and video mode resolutions.</p>
<p>Two exceptions are the <a class="el" href="monitor_guide.html#monitor_size">monitor physical size</a>, which is measured in millimetres, and <a class="el" href="window_guide.html#window_fbsize">framebuffer size</a>, which is measured in pixels.</p>
