The village extends New Road Hill, Woolhampton Lock in the east, West Berkshire Crematorium in the west, Midgham Marsh (south of the A4 road) in the south and to Midgham Green to the north.
For no recorded other reasons, other than confusion with Wolverhampton, the station in Woolhampton 100m east of the area's bounds (which is therefore the nearest station to all but the far western borders of Midgham), changed its name to Midgham railway station in 1873.
