gives a bunch of answers. Here’s one
The drain current of a mosfet is proportional to mobility and the ratio w/l.
Electron mobility is typically 3-4 times that of a hole.
So to have comparable drive power, the sizing (in an inverter) is done such that the lengths are the same, but the width of PMOS is 3-4 times that of NMOS.
