Hi Junting the dimensions of the computational domain should be such that you obtain the desired Reynolds number, given your choice of reference density, velocity, and viscosity. It may be easier though to change these variables to get your target Reynolds number, while keeping fixed your domain (i.e. while keeping fixed your reference length).
