It has alot to do with various things, not just one thing. the taller a coil is the lower the inductance will be, the fatter the wire it will be lower, the more metal that is in contact with or near the coil the higher it will be. But to confuse things alot of time when you add more metal the inductance goes DOWN not up but your tone gets darker. For instance if you read the inductance of a P90 before you slap a brass baseplate on the bottom it will X amount but when the base plate goes on the inductance will drop, but you will lose some treble from the baseplate being there due to eddy currents. confusing eh?
AC resistance is a better guide to how a coil will sound than inductance is for me. A good LCR meter is real useful for making repeatable pickups that all sound the same or as close as you can get without buying a perfect winding computer coil winder.
