When you say pad height, are you referring to the thickness of the brake caliper?
Hopefully this makes sense to you...
Pad Height / Disk Height
Depending on the wheel manufacturer, the Disk or a Pad height is determined to satisfy brake caliper overhang clearance. Although each manufacturer determines their own Disk / Pad heights, they will specify certain heights to specify brake caliper clearance with notations such as High Pad/ Disk, Mid Pad / Disk, and Low Pad / Disk. A High Pad or Disk is for cars with larger OEM calipers or for applications that will use upgraded big brake systems.
As a rule of thumb when comparing 2 wheels of a same size and offset, a High Pad wheel will have a smaller rim depth (lip size) since the mounting surface is raised to clear brakes. A low disk will have a larger lip size since the mounting surface is shorter, which then allows the lip size to be lengthened. Low disk is usually for the rear of cars which have small brake calipers.

Maybe this will help if you still don't understand. The wheels in the pictures below are TE37s in 19x9.5 and 19x10.5 with a +12 offset all around. This specific wheel has a high pad height. In layman's term a big brake kit which positions the caliper closer to the barrel of the wheel and further away from the hub of the wheel will be optimal. As we all know the bigger the rotor generally speaking the closer to the barrel of the wheel the caliper will be located. You can still use a big brake kit that positions the caliper closer to the hub but a spacer maybe necessary for caliper to wheel clearance.
These pictures are courtesy of tony a.k.a. "offsetz33." Due to the high pad clearance of his wheel and the relatively small rotor used with the OEM Brembo kit, it was necessary for him to use a spacer so that his caliper would not rub his wheel.
In the pictures you can see how the wheel bows out or convexes away from the brakes as the spoke get closer to the barrel. This convexing is what allows for the fitment of a bigger brake caliper that is positioned closer to the barrel of the wheel and further away from the hub.

Now here are the same exact wheels on 05-Z's car with a bigger brake kit (a Stoptech 355mm 4 piston kit I believe) which positions the caliper closer to the barrel of the wheel. As you can see there is a lot more wheel to caliper clearance.

Take care.
