how many yards in a cfl football field
Comparison of American and Canadian football The official playing field in Canadian football is larger than the American, and similar to American fields prior to 1912. The Canadian field of play is 110 by 65 yards (101 by 59.4 m), rather than 100 by 53 1⁄3 yards (91.4 by 48.8 m) as in American football. The end zones in Canadian football are 10 yards deeper than American football end zones as the CFL uses 20-yard (18.3 m) end zones. Prior to 1986, however, the end zones were 25 yards, with Vancouver's BC Place the first to use the 20 yard-long end zone in 1983. However, beginning in 2016, the new home of the CFL's Toronto Argonauts, BMO Field, utilizes an 18-yard-long end zone.[3] Including the end zones, the Canadian field is almost 34% larger than the American field (87,750 square feet (8,152 m2) for the Canadian field vs 57,600 square feet (5,350 m2) for the American field). Occasionally, however, the Canadian field will have its end zone truncated at the corners so that the field fits in the infield of a running track. The only example in the CFL is the Percival Molson Memorial Stadium, home of the Montreal Alouettes. The goalposts for kicking are placed at the goal line in Canadian football and the end line in the American game. In Canadian rules, the distance between the sideline and hash marks is 24 yards (21.9 m); in American amateur rules, at the high school level, the distance is 17 yards 2 feet 4 inches (16.3 m), virtually sectioning the field into three equal columns. The hash marks are closer together at the American college level, where they are 20 yards (18.3 m) from the sideline, and in the NFL, where they are 23 yd 1 ft 9 in (21.6 m) from the sideline and the distance between them is the same as that between the goalposts.[4]
Field goal Except in desperate situations, a team will generally attempt field goals only when keeping a drive alive is unlikely, and its kicker has a significant chance of success, as a missed field goal results in a turnover at the spot of the kick (in the NFL) or at the line of scrimmage (in the NCAA). In American high school rules and Canadian football, where a missed field goal is treated the same as a punt, most teams still opt not to attempt field goals from very long range since field goal formations are not conducive to covering kick returns. Even under ideal conditions, the best professional kickers historically had difficulty making kicks longer than 50 yards consistently (the NFL record is 64 yards and the CFL record, 62 yards).[2] If a team chooses not to attempt a field goal on their last down, they can punt to the other team. A punt cannot score any points in American football unless the receiving team touches the ball first and the kicking team recovers it (though it can result in a single in Canadian football), but it may push the other team back toward its own end.
