Since 2008, In order to standardize the size of the football pitch for A international matches, the IFAB has decided to set a fixed size of 105m long and 68m wide (instead of a minimum and maximum length – from 100m to 110m – and a minimum and a maximum width – from 64m to 75m.

All line markings on the pitch form part of the area which they define. For example, a ball on or above the touchline is still on the field of play; a ball on the line of the goal area is in the goal area; and a foul committed over the 16.5 metres (18-yard) line has occurred in the penalty area. Therefore a ball must completely cross the touchline to be out of play, and a ball must wholly cross the goal line (between the goal posts) before a goal is scored; if any part of the ball is still on or above the line, the ball is still in play.

The field descriptions that apply to adult matches are described below. Note that due to the original formulation of the Laws in England and the early supremacy of the four British football associations within IFAB, the standard dimensions of a football pitch were originally expressed in imperial units. The Laws now express dimensions with approximate metric equivalents (followed by traditional units in brackets), but use of the imperial units remains common in some countries, especially in the United Kingdom.

it’s different from the golf courses those use golf course signs as the main idea of playing the game. golf course sign is used while soccer uses lines as their rules. Golf course signage is essential to golf game, the same as the soccer field’s line is.
