    You can observe how much area is shown in your mapView by inspecting the region property.

    map.region.span.latitudeDelta

    gives the current height of the map in degrees of latitude. Latitude degrees are about 69 miles (or 111 kilometers). 

    map.region.span.longitudeDelta

    will give you the width of the map in longitude degrees, but be aware that longitude lines are not parallel and the extent will vary based on the distance from the equator. Much easier IMO to just deal with the first parameter.
