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
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 7.5 m x 5.35 m (seen in the image below), providing enough space to shoot from the free throw line. This small court is perfect for free throw practice, but to enable shooting from a section of the 3 point arc, the court needs to be extended to at least 9 m in length.
Parametric Basketball Court Sizing
The OnCourt 3D Basketball Court Configurator incorporates parametric sizing alongside standard key, half and full sized court schemes. This allows users to select the available space for a court, choose their colours, hoop system and components, to see what the proposed layout will look like.

Irregularly Shaped Basketball Courts
A 16 m deep, 6 m wide court may not be ideal for practising 3 pointers from the lanes, but OnCourt appreciates that the perfect space isn’t always available. Similarly a wide 16 m court which is only 8 m deep will have limitations for play however, these areas can be great for fun and practice for basketball fans who need a court, regardless of size.
Consider Hoop System Dimensions and ‘Overhang’ Distance
Hoop systems are available in a huge range of sizes with varying footprints and overhang measurements. Overhang refers to the distance between the front of the post and the front of the backboard (Overhang is also referred to as ‘projection’). As seen here in the Mega Slam 72 Installation Instructions, the system has a 46 inch overhang. The more compact Mega Slam 60 features a smaller 36 inch overhang.
Portable Hoops and Large Footprints
Portable hoops aimed at home users can often save on costs but with larger footprints than in-ground hoops, they can also reduce available playing space. A commodity in short supply in the average back garden. A Spalding NBA Beast for example, commands nearly 2m footprint from the back of the base to the backboard – valuable playing space consumed by the system.
In-Ground Hoop Advantage
In-ground hoops such as the Mega Slam systems, are anchored to the ground rather than via a weighted base, meaning less space is required behind the hoop, just enough to crank the adjustable height mechanism. The footprint issue is just one of many things to consider before you buy a portable basketball hoop.
Large Tournament Ready Hoop Systems
Basketball Hoops step up in footprint and overhang when we look at the larger tournament ready systems. The 3×3 Street Slammer from Schelde Sports which we installed with Nike for the England Football Team at the 2020 Euros, takes up a whopping 4.42 m footprint with a 141 cm overhang. These hoops are undoubtedly impressive if the necessary space is available!
Do You Have Enough Space For Basketball?
When all things are considered, there’s always enough room for basketball, be it a giant full size court or a tiny free throw shooting space. We’ve collated a number of standardised basketball court schemes in the 3D Basketball Court Configurator, where you can compare the various sizes.
