It depends on the format you are playing, as the pitch size in football can vary greatly. Even within those formats, football pitch markings and dimensions can vary considerably, while 5v5 pitch size has the curved penalty areas, whereas the 11 a-sides have an 18-yard box.
The following are the FA recommended pitch sizes for five-a-side, seven-a-side, and 11-a side foot, whether you are laying your own football pitch or looking for one to play on.
5-a-side football pitch size
The recommended dimensions are 40 X 30 yards as the 5-a-side football pitches can vary in size. The penalty area should be 6.5 yards from the center of the goal line regardless of the size of the pitch, as they are formed of semi-circles at either end of the pitch.
With or without center circle or even halfway line pitch markings, you can easily play a five-a-side. Three yards of width is the recommended goal size for a 5-a side.
7-a-side football pitch size
The recommended size here is 60 x 40 yards, as the seven-a-side pitch dimensions can also vary. Seven a-side pitches have rectangular penalty areas that are 18 yards wide and 10 yards from the goal line, unlike the five-a-side pitches.
A center circle here is an optional one, as with five-a-side. The penalty arcs are positioned at the edge of the penalty area with the curve that faces away from the goal as they are most commonly known as Ds. From the goal line, the penalty spot should always be 8 yards.
11-a-side football pitch size
According to the FA regulations, they should be falling between 100-130 yards in length and 50-100 yards in width as the 11 a-side pitch measurements can vary considerably. From the center of the goal line along with the penalty spot, that should be 12 yards from the goal no matter the overall size of the pitch, as the penalty area should be measuring 18 yards away.
