query: How long is a soccer field?
passage: Football pitch
The pitch is rectangular in shape. The longer sides are called touchlines. The other opposing sides are called the goal lines. The two goal lines must be between 45 and 90m (50 and 100yd) wide, and be the same length.[3] The two touchlines be between 90 and 120m (100 and 130yd) long, and be the same length.[3] All lines on the ground must be equally wide, not to exceed 12cm (5in).[3] The corners of the pitch are marked by corner flags.[4]
passage: Australian rules football playing field
Smaller fields are generally used for junior football; some are purpose-built, and some are temporarily marked out within the confines of full-sized oval; as for a senior match, there are no fixed dimensions for a junior-sized field. The Western Australian Football Commission advises that a good rule of thumb is to set the length of the field equivalent to 3½ times the length of an average kick of the age group playing.
