Basketball Court Dimensions & Sizes

What Are The Dimensions Of A Basketball Court?

Beyond the differences in governing bodies, FIBA, NBA etc. court sizes in basketball can vary more than many sports. The focal area of the key has enabled condensed versions of the game, played on ‘half courts’ and the key area allows for further restricted, but usable space. Let’s start with a FIBA full basketball court before drilling down into the smaller spaces.

FIBA Court Dimensions Table	Metric	Imperial
Court Length	28 m	91.86 ft
Court Width	15 m	49.21 ft
Centre Circle Diameter	3.6 m	11.81 ft
3 Point Line (from hoop centre)	6.75 m 6.6 m in corners	22.15 ft 21.65 ft in corners
No Charge Arc (from hoop centre)	1.25 m	4.1 ft
Key Width	4.9 m	16.08 ft
Free Throw Line	4.6 m	15.09 ft

Full FIBA Basketball Court Measurements

Slightly smaller than an NBA Basketball Court (94 x 50 ft), the playing surface of a FIBA full court should measure 28 m in length by 15 m in width (91.9 by 49.2 ft). If you’re planning a space for any court, be sure to account for ‘run-off’. A minimum of 2.05 m is recommended for professional basketball and 1.05 m for a community or club level basketball game.

The 3 point arc on FIBA courts is 6.75 m and 6.6 m at the sides/corners. These distances are measured from the centre of the hoop. The free throw line is measured from the front of the blackboard and is ever so slightly further from the hoop than an NBA court (15 feet) at 4.6 m (15.09 ft).

What Are The Dimensions Of A Half Court Basketball Court?

Half courts feature the same line marked dimensions of a full court, but only one end, with one basketball hoop. Purpose-built half courts are rarely long enough to be truly half of a full court. Foul line distance, 3 point arc etc all remain exactly the same as on a full Court. Some variations exist, in 3×3 Basketball competition for example, the free throw arc is not included and a restricted area is marked 11 m from the baseline. 

How much space is Required for A Basketball Key Court?

Key Courts as the name suggests, require enough space to accommodate a basketball key. The table above indicates that a FIBA regulation key is 4.9 m wide by at least 4.6 m long. When planning key court lines, you need to consider the footprint of the basketball goal as this can directly impact the available space beyond the free throw line, where longer distance shooting practice takes place.

OnCourt’s smallest Basketball Key Court requires just 5.28 x 7.33 m, providing enough space to shoot from the 4.6m foul line. This small court is perfect for free throw and lay-up practice. To enable shooting from a section of the 3 point arc, the court needs to be extended to at least 9.38 m in length.
