Basketball Court Length: Official Dimensions for NBA, WNBA, NCAA, High School & FIBA

A standard basketball court length is 94 feet (28.65 m) for NBA, WNBA, and NCAA play. High school courts are shorter at 84 feet (25.60 m), and FIBA-regulated courts used in international and Olympic competition measure 91 feet 10 inches (28 m). The right number depends on which governing body sets the rules.

How Long Is a Basketball Court? (Quick Answer)

The most common basketball court length you'll encounter — in professional play, college games, and most televised basketball — is 94 feet. That said, not all courts are the same size. Youth courts are noticeably shorter, FIBA courts are slightly shorter than NBA courts, and recreational setups often use half-court dimensions.

Here's the full picture at a glance:

How to read this table: Feet (ft) figures apply to US courts. Metric figures apply to FIBA-regulated courts in the UK, Europe, Australia, and international competition. Indoor and outdoor courts follow the same regulated dimensions.

Basketball Court Length by Level of Play

NBA Basketball Court Length

An NBA court is 94 feet long and 50 feet wide — or 28.65 m × 15.24 m. In yards, that's roughly 31.33 yards in length and 16.67 yards wide. As noted according to Wikipedia, NBA courts measure 94 by 50 feet (28.7 by 15.2 m), while FIBA courts are slightly smaller at 28 by 15 meters (91.9 by 49.2 ft).

What's often overlooked is that NBA arenas don't have a fixed minimum buffer zone around the court perimeter. Most arenas include a safety area between the sideline and the first row of seats, but the exact dimension varies from one building to the next. In practice, teams and arena managers negotiate this space based on the physical layout of each venue.

The 94-foot length is long enough that players routinely cover full-court distances during transition play — something coaches at lower levels sometimes use when arguing for smaller courts in youth development.

WNBA Basketball Court Length

WNBA courts are the same size as NBA courts: 94 feet × 50 feet. This is worth stating clearly because it gets conflated with FIBA dimensions fairly often.

One notable difference from the NBA: the WNBA does not use a restricted area arc under the basket. The key is 16 feet wide — same as the NBA — but that defensive protection zone beneath the hoop simply isn't part of WNBA rules.

NCAA (College) Basketball Court Length

College courts in the US match NBA dimensions in length and width: 94 feet × 50 feet. The length is identical. Where college courts differ is in other markings — specifically the key width and the 3-point line distance.

The NCAA key (free throw lane) is 12 feet wide, compared to 16 feet in the NBA. The men's 3-point line sits at 22 feet 1.75 inches from the basket; the women's line is closer at 20 feet 9 inches. So the court is the same size — but it plays differently.

FIBA and Olympic Basketball Court Length

FIBA courts are 91 feet 10 inches long and 49 feet 3 inches wide (28 m × 15 m). They're slightly smaller than NBA courts — about 2 feet shorter in length and 9 inches narrower in width.

FIBA also regulates domestic leagues in the UK, Europe, and Australia. For those competitions, the rules are slightly more flexible:

The flexibility at Premier, Club, and Community level exists because not every facility was built to International spec. Older sports halls in particular often fall within the 26 m range — so the rules accommodate them rather than excluding them from competition.

High School Basketball Court Length

High school courts are 84 feet long and 50 feet wide (25.60 m × 15.24 m) — a full 10 feet shorter than an NBA or college court.

That 10-foot reduction isn't arbitrary. Younger players cover less ground per possession, and smaller courts keep the game more manageable at the skill level typical of secondary school play. In practice, most high school gymnasiums were built to this spec, so the standard has stayed consistent across US states.

Junior High and Youth Court Lengths

Youth courts scale down further as age and skill level decrease:

Junior high courts typically match high school dimensions, though some states apply their own specifications — so it's worth checking with the relevant state athletic association if you're building or marking a court for junior high competition.

Half Court Basketball Dimensions

A half court is exactly what it sounds like — one end of a full court, divided at the midcourt line.

Half courts are widely used for 3-on-3 recreational play, backyard setups, and informal pickup games. FIBA officially adopted 3-on-3 basketball as a discipline, and those games are played on a half court. If you're building a home court and space is tight, a half court is the most practical option that still allows for meaningful play.

Total Court Area and Buffer Zones

The playing surface area is one number. The total space a court actually needs is larger.

FIBA specifies a run-off zone of 2.05 meters on each side of the court, plus 2 meters for team benches and officials along the sidelines. That's what pushes the total facility requirement up to 677 m².

The NBA doesn't publish a fixed minimum buffer requirement — arena dimensions vary considerably. The reason buffer zones exist at all is straightforward: players moving at full speed regularly travel beyond the sideline and baseline. Without adequate run-off space, the risk of collisions with equipment, benches, and spectator areas increases significantly.

Basketball Court Markings and Their Relation to Court Length

Sidelines and Baselines

The sidelines run the full length of the court — 94 ft in NBA/NCAA, 84 ft in high school. The baselines (also called endlines) run the width behind each hoop: typically 50 ft (15.24 m) for US courts, 49 ft 3 in (15 m) for FIBA. FIBA regulations specify that all court marking lines must be 50 mm wide in a colour that contrasts with the playing surface.

The Key (Free Throw Lane)

The key — also called the paint or the lane — is the rectangle running from the baseline to the free throw line. Its width varies by level:

The key length (baseline to free throw line) is consistent at roughly 15 feet across all senior levels.

The Free Throw Line

The free throw line is 15 feet from the backboard in NBA, NCAA, and high school play. FIBA puts it marginally further at 15 feet 1 inch (4.60 m). This is one of the few measurements that stays almost identical regardless of which level you're looking at.

The 3-Point Line

The 3-point arc is where the differences across levels become most noticeable. As detailed according to Wikipedia, the distance from the basket to the 3-point line varies by competition level — in the NBA the arc is 23 feet 9 inches (7.24 m), while in FIBA, WNBA, and NCAA play the distances are shorter.

The NBA reduced its corner 3-point distance from 23 ft to 22 ft in the early 1990s specifically to encourage more scoring — and corner 3s have since become one of the most valuable shots in modern NBA strategy.

Center Circle

The center circle marks where the opening tip-off takes place. NBA and NCAA courts use a 12-foot (3.66 m) diameter circle. FIBA courts use a slightly smaller 11 ft 10 in (3.60 m) circle.

The Restricted Area Arc

Located directly under each basket, the restricted area arc prevents defenders from drawing charging fouls by planting themselves beneath the hoop. The arc has a 4-foot (1.22 m) radius in the NBA, NCAA, and FIBA. Neither the WNBA nor NCAA Women's game uses this marking.

Backboard and Rim Dimensions

These stay consistent across most levels, which is worth knowing if you're building or fitting out a court:

The 10-foot rim height is one of the few constants that doesn't change from youth leagues all the way up to the NBA. Interestingly, adjustable hoops used in youth programs technically allow lower heights, but formal competition at junior high level and above keeps the hoop at 10 feet.

Why Do Basketball Court Lengths Differ Across Levels?

The short answer: different governing bodies, different facilities, different players.

The NBA sets its own standards for professional play in North America. FIBA governs international competition and domestic leagues across Europe, the UK, and Australia — and its metric-based system naturally produces slightly different numbers.

High school courts follow guidelines set by state athletic associations, most of which have standardised on 84 feet for decades based on the physical layout of school gymnasiums built across the US throughout the mid-twentieth century.

Youth court reductions are more deliberate. A 94-foot court for 8-year-olds produces a very different game than on a 50-foot court — shot attempts from further away, more fatigue, fewer scoring opportunities. Coaches and youth development organisations broadly agree that scaled-down courts produce better fundamental skill development at lower age groups.

FIBA's flexibility model — allowing domestic courts to range from 26 m to 28 m — reflects a practical reality: not every sports hall across Europe and Australia was built to Olympic specification. Allowing a 2-metre range means more facilities qualify for organised competition without expensive renovation.

Basketball Court Length for Home and Recreational Use

If you're planning a home or community court, the realistic options are:

• Full court (94 ft × 50 ft): Requires a slab of roughly 100 ft × 55 ft when accounting for run-off space. This is feasible for larger properties but demands significant space and cost.
• Half court (47 ft × 50 ft): The most practical option for home use. Fits in a standard double-driveway footprint with modest run-off space added. Allows full 3-on-3 play and most individual skill practice.
• Reduced half court: Some recreational setups go as small as 30 ft × 25 ft for very young players or extremely limited spaces.

Surface material doesn't change the regulated dimensions — those stay the same whether you're building on hardwood (indoor), asphalt, or concrete. Asphalt is the most common outdoor choice: it's durable, provides a consistent ball bounce, and handles weather reasonably well.

Hardwood is standard indoors for professional and college courts, primarily because it offers better shock absorption for players' joints over extended use.

Conclusion

Basketball court length is 94 ft for NBA, WNBA, and NCAA play, 84 ft for high school, and 91 ft 10 in for FIBA. Youth courts scale down further by age group. Half courts run 47 ft (NBA/NCAA) or 42 ft (high school). These dimensions are fixed by each governing body and apply equally to indoor and outdoor surfaces.

Frequently Asked Questions

Is an NBA court the same length as a college court?

Yes. Both NBA and NCAA courts are 94 feet long and 50 feet wide. The key differences are in markings — the NCAA key is 12 ft wide versus 16 ft in the NBA, and the 3-point line distances differ.

How long is a half basketball court?

An NBA or NCAA half court is 47 feet long and 50 feet wide. A high school half court is 42 feet long. Half courts are standard for recreational 3-on-3 play.

How does an NBA court compare to a FIBA court in length?

An NBA court is 94 ft (28.65 m) long. A FIBA court is 91 ft 10 in (28 m) — about 2 feet shorter. The width difference is similarly small: 50 ft vs. 49 ft 3 in.

H3: Are WNBA and NBA courts the same size?

Yes — both are 94 ft × 50 ft. The main difference is that the WNBA does not use a restricted area arc under the basket, and the WNBA 3-point line is slightly closer to the basket than the NBA's.

How many laps around a basketball court equal a mile?

On an NBA or NCAA court, you'd need to run approximately 18.33 laps to cover a mile. On a high school court, that figure rises to around 19.7 laps.
