What are the physical dimensions of the Four Thirds and APS-C sized sensors?

Here is a useful reference:

Basically, the APS-C sensor is 25.1mm x 16.7mm (419 mm2)
while the 4/3 sensor is 18mm x 13.5mm (243 mm2)

So the APS-C sensor is about 70% larger.

There are variations on the APS-C sensor, which are still refered to as APS sensors.
