    As magnification increases the diameter of the field of view decreases.

    justify the higher the magnification the smaller your field of view?

    Why field of view decreases as a magnification increases?

    field of view obviously gets smaller as it appears closer (more magnified)

    why the higher the magnification the smaller your field of view? it seems it would be just the opposite.

    Is there a common fixed measuring instrument?

    The text of this topic could perhaps have been better expressed. The *absolute diameter* of the field of view does not decrease; it is defined by a disc within the eyepiece which is always the same distance from the eye, so that it cannot change. What does reduce, as the magnification increases, is the *content* of that field, i.e. the range or span that can fit within it. Increasing the magnification has exactly the same effect as bringing things closer to the eye; they look larger, and therefore they need a wider range of vision to be seen in full - a range which is eventually wider than the available field of view allows.
