7v7 and 9v9 fields are mandatory in PAGS for the 2016-2017 soccer year, beginning with play in September 2016. The sizes of 7v7 and 9v9 fields are different and a 7v7 field SHOULD NOT be used for a 9v9 game, or vice-versa. The permissible field dimensions are a range of both length and width. Clubs may use a field that meets these ranges while fitting into available field space. The fields MUST be marked according to the standards for each size field. 7v7 field MUST contain a build out line, Where possible, the build out line should be lined in a different color from the remaining field lines. If the build out line is not painted on the field cones should be placed on the touchlines as markers.
