There is no 'official' size. This is one of the beauties of cricket, all the grounds are different. The playing pitch (wicket) is 22 yards long, but the outfield varies. If you watch on TV you can see that various wickets are prepared so that where the grass is worn from one game, it does not impact on another which is played on a different wicket which runs parallel. The ground at Tunbridge Wells in Kent even has a tree near the boundary.
