When calculating the inductance of a coil, do you input the height of the coil to the formula inclusive of the wire insulation, or the height of the coil exclusive of the wire insulation?

The insulation does not affect inductance, so use the diameter of the bare wire. The insulation will affect Q and self-resonant frequency.
Thank you. I'm attempting to match the resonant frequency of my primary tank circuit to the resonant frequency of the secondary tank circuit (Tesla coil).
