Here is the output of the touchpad-edge-detector:
sudo touchpad-edge-detector /dev/input/event5
Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event5
Move one finger around the touchpad to detect the actual edges
Kernel says: x [1240..5702], y [1102..4750]
Touchpad sends: x [1241..5703], y [1105..4820] |^C
Touchpad size as listed by the kernel: 87x54mm
Calculate resolution as:
x axis: 4462/<width in mm>
y axis: 3648/<height in mm>
Suggested udev rule:
