This important term describes the actual width of your scope's sight picture at a specific distance. For instance, the Zeiss Diatal ZM/Z 8x56 MC gives you a sight picture that is 15 feet wide at a range of 100 yards.
Field-of-view is a function of magnification and the focal lengths of the objective and eyepiece lenses. But remember this: The higher the magnification, the narrower the field-of-view.
