The key measurements in Australian Rules Football are the size of the ball and the spacing of the goal and behind posts. For senior men’s matches, the ball is roughly 72 centimetres around its long axis, while the two goalposts stand 6.4 metres apart. Those figures help explain why a clean kick can travel a long way—and why even a small miss can turn a goal into a behind.
There isn’t one fixed size for every footy ground. The Laws allow a range of oval dimensions, and the ball is smaller for women’s competitions and junior players. Here’s a practical guide to the standard measurements, what they mean on the field, and which parts of a player’s kit have no set dimensions.
Standard Australian Rules football dimensions
The match ball and goalposts are the main pieces of equipment with defined measurements. The figures below reflect common senior standards; local junior competitions may use smaller balls or different venue specifications.
| Item | Standard measurement | What it means |
|---|---|---|
| Senior men’s football | 720–730 mm circumference around the long axis; 545–560 g | The full-size oval ball used in senior men’s matches. |
| Women’s football | 685–695 mm circumference around the long axis; 455–480 g | A smaller, lighter match ball used in women’s competitions. |
| Goalposts | At least 6 m high; 6.4 m between the two posts | A kick passing between them above the crossbar-free goal line scores a goal. |
| Behind posts | At least 6 m high; 6.4 m from the nearest goalpost | These mark the outer scoring posts on each end line. |
| Goal-post padding | At least 2 m high and 35 mm thick | Padding covers the lower part of each post for player safety. |
Football size, weight and shape
An Australian Rules football is oval, with pointed ends and a raised seam. Its shape helps it travel long distances when kicked, but it also makes the bounce less predictable than a round ball. Players often practise judging the flight and bounce because a ball that lands end-first can shoot sideways or change direction.
The senior men’s ball weighs between 545 and 560 grams and measures 720–730 mm around its long axis. The smaller women’s match ball measures 685–695 mm around the same axis and weighs 455–480 grams. A lighter, smaller ball can be easier for players to handle and kick, though grip, weather and playing conditions matter too.
Junior balls are generally smaller again, but there isn’t one universal junior size for every age group and competition. Check the rules set by your league or club before buying a ball. A ball labelled “size 4” or “size 3” may differ slightly by brand, so its stated measurements are more useful than the label alone.
Goalposts and scoring area
At each end of the ground, two taller goalposts sit 6.4 metres apart. Two shorter outer posts—the behind posts—are placed 6.4 metres beyond the nearest goalpost on either side. A ball kicked through the two central posts for a goal scores six points; a behind scores one point when the ball passes between a goalpost and a behind post, or meets other scoring conditions in the Laws.
The posts must be at least 6 metres high. Their padding is there to reduce the risk of injury when players contest the ball near the scoring area. At grounds used for high-level matches, the posts are often taller than the minimum, so the visible height may vary from venue to venue.
Ground dimensions and markings
The playing surface is part of the match setup rather than a piece of equipment, but its measurements give the goalposts useful context. Under the Laws, an oval ground can be 135–185 metres long and 110–155 metres wide. That is a broad range: a ground at the smaller end can feel crowded, while a larger oval gives teams more room to spread the ball and run into space.
Key markings help organise play. The centre square is 50 metres by 50 metres. The goal square in front of each scoring end is 9 metres wide and 6.4 metres deep. Grounds also have centre circles and 50-metre arcs. These markings guide restarts and positioning, but they do not change the basic dimensions of the ball or posts.
What about boots, mouthguards and other kit?
Boots, mouthguards, helmets and padding do not have one standard length or width in the Laws of Australian Rules Football. Players choose boots that suit the surface and their feet, while clubs and competitions may set safety or uniform rules. A mouthguard should fit securely and protect the teeth; its exact dimensions depend on the player.
In other words, when someone asks for the standard equipment dimensions in footy, the clearest measurements to give are those for the match ball and scoring posts. Other protective gear is selected for fit and safety rather than a single prescribed size.

Frequently Asked Questions
How big is a standard AFL football?
A senior men’s football measures 720–730 mm around its long axis and weighs 545–560 grams. The women’s match ball is smaller and lighter: 685–695 mm and 455–480 grams.
How far apart are Australian Rules goalposts?
The two central goalposts are 6.4 metres apart. Each behind post is another 6.4 metres out from the nearest goalpost.
Are all Australian Rules grounds the same size?
No. The Laws allow a playing surface between 135 and 185 metres long and 110 and 155 metres wide. The oval’s size can affect how much space teams have to attack and defend.
Do junior players use a full-size football?
Junior competitions commonly use smaller, lighter balls, with the size chosen for the age group and local rules. Check your league’s requirements, as junior ball sizes can vary.
Final Thoughts
The senior men’s footy is about 72 centimetres around its long axis, while the women’s version is smaller and lighter. At each end of the ground, goalposts are 6.4 metres apart, with behind posts set the same distance outside them. Ground size and some kit choices can vary, so for a specific match or junior competition, the local rules are the best guide.
