    Depends fundamentally on the distance from the screen to the pinhole and
    the size of the original pinhole to begin with.

    Optimum sharpness is obtained about when the diffraction pattern of the aperture matches the spot size from classical geometric ray tracing at
    the plane of the screen.

    The other more exotic form of pinhole enlargement leads to coded
    aperture masks which is an altogether more interesting subject.

    Bigger pinhole is brighter so you have to trade one against the other.

    Regards,
