A football pitch looks like a giant green painting covered in white geometry, but every line is a rule frozen in paint. The touchlines run along the long sides, the goal lines run behind each net, and the halfway line splits the pitch into two equal halves so both teams defend one end and attack the other. Without these markings, referees could not decide throw-ins, corners, or penalties. World Cup pitches are about 105 metres long and 68 metres wide, and every stadium uses the same line layout so the game feels identical from Mexico City to Vancouver.

All the lines on a pitch are part of the playing area. If the ball is touching a line, it is still in play, which is why tight calls along the touchline are so dramatic!
