Question

What is the radius (in metres) of an AFL field around the white line?

Answer 1

thats a very hard question as in afl there is no sepefic ground sive but I'm sure if you searched something like mcg radius or  scg radius you could find radius for different grounds

Answer 2

there are two radii for an oval, the minor and major ( minor = shorter measurement, major = Longer measurement)

I think what you are asking is for the circumference/ perimeter of the Oval. The radius is from the middle to the edge, the diameter is from edge to edge, and the perimeter or circumference is around the edge.

I will use the MCG for the example.

To calculate the perimeter or circumference of an ellipse (Oval) use the following:

2XPI(SQRT((aSQRD + bSQRD)/2))

So for the MCG it looks like this:

2X3.14159265(sqrt(165sqrd + 135sqrd)/2))

So in the end here are the measurements for the MCG:

MCG Minor Diameter = 135M

MCG Major Diameter = 165M

MCG Minor Radius =67.5M

MCG Major Radius = 82.5M

MCG Circumference = 947.1782M

Here's some of the other stadiums:

Sydney = 889.7421M

Colonial ( Melbourne) = 912.4799M

Football Park (Adelaide) = 941.5768M

Gabba = 941.6501M

Subiaco - Perth = 929.6567M

Answer 3

well there is no actual set size, but most are about 400m around!!!!!

Answer 4

will this do for an answer ?!

All measurements and distances in Aussie Rules are given in meters (m). One meter = 1.1 yards approximately. To convert measurements from meters to yards just add 10 percent to the measurement.

Unlike other games of football Aussie Rules is played on cricket ovals; thus, there are no standard dimensions for a football field (usually called "ground" or "paddock"). The field should be an oval between 135 and 185 meters in length and 110 and 155 meters in width. (The Melbourne Cricket Ground is considered an ideal surface; its dimensions are 165m length by 135m width.) These dimensions make it the largest playing field of any code of football. The boundary is marked with a white line drawn a few meters from the stands.

The goals are two sets of posts erected at the far ends of the oval; the boundary forms a straight line through the posts. The inner set of posts is the goal posts, 6.4 meters (7 yards) apart, and at least 6 meters tall. Two behind posts are set 6.4 meters from the inside of each goal post, and must be at least 3 meters tall. All posts must be padded to a height of 2 meters.

A goal square (actually a rectangle) extends 9 meters into the ground from the goal posts, and is 6.4 meters in width.

A radius is drawn on the oval 50 meters from each goal. This merely serves as a range finder; most AFL players can kick a goal from this line, and perhaps beyond.

The center circle is marked at the precise center of the oval, 3 meters in diameter, bisected by a lateral line extending 2 meters either side of the diameter, and dividing the field in half. A center square is centered on this, 45 meters on each side. These markings control the conduct of center bounces, as will be seen later.

Ground Sizes

As we stated above, there is no standard size for an Aussie Rules ground. The table below shows the sizes of all grounds currently used by the AFL. Measurements are from goal to goal and boundary to boundary:

Sydney Cricket Ground (SCG) 147m x 136m

Colonial Stadium - Melbourne 159m x 130m

Football Park - Adelaide 165m x 133m

Wollongabba Cricket Ground (the "Gabba") - Brisbane 160m x 139m

Melbourne Cricket Ground (MCG) - Melbourne 160m x 139m

Optus Oval - Melbourne 160m x 139m

Manuka Oval - Canberra 164m x 136m

Subiaco - Perth 170m x 122m

York Park - Launceston 165m x 135m

Baytec Stadium (formerly Kardinia Park/Shell Stadium) - Geelong 169m x 115m

Stadium Australia - Sydney 159m x 118m
