    The phase field method is frequently employed to simulate evolution
    of rather complex microstructures. In order to accurately describe the
    real kinetics of a specific material system, the phase field parameters
    must be calibrated to standard thermodynamic quantities such
    as interface mobilities or interface energies. This letter presents
    a convenient method, based on thermodynamic modelling of
    shrinking of a single grain embedded in single crystal (matrix), how
    to calibrate the phase field parameters. It also shows, how the required
    thermodynamic quantities can be met by proper rescaling of a phase
    field simulation carried out for given phase field parameters.
