No. These are the minimum recommended sizes. The normal size battlefield for a game of between 2,000 and 3,000 points is 48" x 72" (4' x 6') and players are encouraged to use this. The minimum sizes are based on the folding card battlefields Games Workshop produces. These are ideal when space is an issue or for smaller games. For example, we prefer a 44" x 60" battlefield for a game of 1,000 or 1,500 points, rather than the more traditional 48" x 48" battlefield. We find the smaller, rectangular shape more pleasing.
