How can you make a football field?

Marking out a hockey field is not the easiest thing to do. Most modern artificial turfs already have the markings on them as part of the coloured weave they are made of. However, there are still many teams and leagues that play on grass, either because they have no easy access to an updated turf or they choose to do so out of tradition and skillbuilding (yes, it takes a lot more skill to play on sometimes unkempt grassy fileds than a wellbuilt, evenly spread turf). The simplest thing to do is spray the lines in paint or lay down chalk along the required places to mark out the playing area. **I would like to make it clear that I have never done this, and this should NOT be taken as a manual on DIY linemarking. If you need to do this, seek a professional.** Firstly, find a large enough patch of lawn or grass to play on. A regulation turf is 91.40 by 55.00 metres (don't know what that is for Imperials), plus at least 2-3 metres unobstructed at the sides and 4-5 metres at the ends to create a runoff zone. So you'd want around 100 by 60 metres in all. Next, mark one corner with a small peg. Using strong string, measure out 55m one way, and 91.40m perpendicular to it. If possible, ensure that the longer axis of the field runs North-South to avoid issues with glare. Then do the same there: put a peg in, then finish the rectangle with another end and another sideline. If you want to check that the field is not askew, the diagonal distances should be a) the same and b) somewhere around 106.5m. You now have the main outline done, and it can be chalked or painted- your choice. The lines are 50mm wide for their whole length and are part of the field of play- they go inside the boundary strings with the outer part of the line matching them. To continue with this here would take some hours to get a brief description down, so I will not do it. From here you need the circles, halfway and 23m lines, and all the other little marks that are needed on a hockey turf. The full specifications are in the rulebook and on the FIH website, and could probably be sent to you if you asked nicely.
