Almost everybody talks about acres without having a clear idea of what they are. I am astonished that in the UK we have not embraced the hectare. (The square root of 10 is approximately 3.1623). The maths is straight forward, however be careful not to get confused with the language as the following example illustrates:Ī square with sides each 10 metres long has an area of 100 square metres.Ī square with an area of 10 square metres will have four sides each 3.1623 metres long. Another way is to think of rectangular shaped ‘blocks’ of land with sides the length of a 100 metre running track, or the length of a non-olympic swimming pool which is often 25 metres. To estimate these land areas in hectares people can think of their favourite sports field from the above list. I think it’s far more difficult to estimate land areas with reasonable accuracy if acres are used. It’s sad that many Estate Agents (Real Estate Companies) use acres not hectares. The rules of the MLB do not apply to other leagues and so in areas where land is at a premium, the fields in lower leagues might be smaller than the minimum in the MBL. The exact shape of the outfield varies from field to field, but using the layout shown in the above diagram, the area of Major League Baseball fields can be shown to vary between 0.83 ha and 1.12 ha. The field dimensions used in Major League Baseball MLB) are laid down in the Official Rules. Thus, the maximum size of the field is a rectangle 144 m in length and 70 m in width giving an area of 10080 m² (which is just over 1 ha). In addition, there is an ‘in-goal area’ that extends a maximum of 22 m behind the goal line. The maximum width of a rugby field is 70 m and the maximum length between the goal posts is 100 m. The laws and regulations of rugby dictate the maximum size of rugby fields international matches are invariably played on fields that are of maximum size. The associated diagram is typical of many club fields and not of Lords. If it is assumed to be circular with a perimeter of exactly 400 m, its area would be 1.27 ha. The author has paced the boundary and found it to be about 400 m. The cricket ground at the author’s hometown is roughly circular and is typical of many cricket fields up and down the country. After allowing for corners having been rounded, it has an area of 1.43 ha. Lords Cricket Ground, the home of the MCC, is played on a rectangular field 136 m long and 109 m wide with well-rounded corners. This only specifies the length of the cricket pitch (20.12 m) it does not specify the distance of the boundary from the pitch. The laws of cricket are maintained by the Marylebone Cricket Club (MCC). Non-international matches may be played on fields between 90 m and 120 m long and 45 m and 90 m wide.Ĭricket (Typically 1.25 ha Lords 1.43 ha) The smallest international football field is therefore 0.62 ha and the largest international football field in 0.82 ha. The Federation Internationale de Football Association (FIFA) dictate that for international matches, the length of the pitch shall be between 100 m and 110 m and its width shall be between 64 m and 75 m. If the straight section is shorter, then the area increases until eventually we have a perfect circle which would have an area of 1.27 ha.įootball (International size: 0.62 ha to 0.82 ha) If this section is 50 m, then the area inside the track is 1.194 ha (shown in green on the associated diagram). The IAAF does not define the length of the straight section. An athletics track is 400 m long (measured 20 cm from inside perimeter). The International Amateur Athletic Association has laid down the rules for athletic tracks that are used in competitions. The associated diagrams are all at the same scale (1:20 000 originally but may look different on screen).Īthletics (Typically 1.2 ha inside the track) This article lists a number of sports whose fields are of the order of a hectare in size. In some sports the size of the field is fixed in others, the size of the field can be adjusted within limits to suit the land that is available. Many sports fields have an area that is comparable to a hectare. Article (including diagrams) by Martin Vlietstra.Ī: It is the equivalent of a square, each side having a length of 100 m. So perhaps it will help to relate this very useful measure to the sizes of sports fields. One of the least known metric units – and one which journalists and estate agents seem to struggle with – is the hectare (ha).
