So with the small plastic pedals they are 9 1/4 tall, this is with the pedal faces mounted in the middle location, they can be raised or lowered 3/4".
The flat metal pedal faces sit at roughly the same height with the gas having up and down adjustment (3/4") while the clutch and brake have side to side adjustment along with the up and down.
On top of all that theres a tilt and height adjustment bracket which is optional, but all my measurements were taken while using this bracket set as high as it goes and tilted as far forward as possible.
I hope that helps
