Does anyone know if there is supposed to be a 'standard' height or distance from floor level to the keybed on an acoustic piano?

I am building a new office/desk area which will house my keyboards (weighted piano controller and 9000pro) and computer. Ideally I would like the height of the weighted controller to be as close as possible to the height of a real (acoustic) piano.

There is always the option of going to a piano store with a tape measure, but I thought I would ask the learned knowledge base first.

Kind regards,
Mark
