Answer:
Not exactly. A standard hockey field outline is exactly 91.40m x 55.00m while a soccer pitch outline can vary in width between 45m - 90m, and in length from 90m - 120m (as long as the touch line is longer than the goal line). There is a possibility that a soccer field may have the exact dimensions of a hockey field in outline only. There are also the differences of a circle (scoring area) against two rectangles (penalty box), and the absence of the 23m lines in soccer or the centre circle in hockey. There are additional marks required on a hockey field that a soccer pitch does not contain.
