Back in the day when soccer was in its infancy, soccer field layout was rather irregular in its dimensions and this created several problems for the players. One player from, say, York would play on a field that was 60 yards long, while the guys in Liverpool would play on one that was 140 yards. Obviously, when either team played on the competitors field, they were at a loss.
That is why, over time, soccer field dimensions were regulated, first by the Football Association, the first soccer organization in history, created by the English in the late 19th century, then by FIFA.
Todays dimensions of soccer fields still offer some room for variation, because not all pitches can be made on a same exact perimeter. So, the width of the field can range from 50 to 100 yards officially, but its rarely the case with modern soccer fields that they hit these extremes. The length can range from 100 yards to 130, but you cant have a pitch that would be 100 yards wide and 100 yards long, obviously.
The field is split in half by a center line, which has a symmetrical distance towards each of the widths and there is a center circle at the middle of this line, which is...
