A standard NBA basketball court measures 31.33 yards long and 16.67 yards wide. Converted directly from feet, a professional court spans 94 feet in length and 50 feet in width, while FIBA and international courts are slightly shorter at 91.9 feet, translating to roughly 30.63 yards long and 16.4 yards wide. When you're watching a game or planning a backyard installation, thinking in yards helps contextualize the sheer physical space players cover during a fast break.
Understanding these measurements goes beyond simple math. It impacts spacing, tactical execution, and facility construction. Whether you're an architect designing a multi-purpose gymnasium or a fan curious about spatial metrics, knowing the exact conversion between feet, inches, and yards clarifies how different basketball governing bodies standardize their playing surfaces.
Official Basketball Court Dimensions in Yards
Professional basketball measurements are traditionally recorded in feet and inches in North America, but converting them to yards gives a clearer picture of field-sport scale. Let's break down the exact numbers across different levels of play.
National Basketball Association and College Courts
In the NBA and NCAA, the playing floor measures 94 feet long by 50 feet wide.
- Length: 94 feet equals 31.33 yards (94 divided by 3).
- Width: 50 feet equals 16.67 yards (50 divided by 3).
- Total Area: The entire playing surface covers roughly 4,700 square feet, which equals about 522 square yards.
FIBA and International Courts
International competition governed by FIBA uses slightly different metrics. International courts measure 28 meters by 15 meters.
- Length in yards: 28 meters is about 91.86 feet, which totals 30.62 yards.
- Width in yards: 15 meters is about 49.21 feet, which totals 16.4 yards.
High School and Rec Center Courts
Most high school gymnasiums feature courts that are slightly more compact to fit multi-sport school facilities.
- Length: Typically 84 feet, which equals 28 yards.
- Width: 50 feet, keeping the standard 16.67-yard width.
Key Court Markings Measured in Yards
A basketball court isn't just an open rectangle. It's packed with precise lines that dictate scoring value and player positioning. Converting these internal features to yards reveals how tight high-pressure areas really are on the floor.
The Three-Point Line
The distance of the three-point arc varies depending on the league. In the NBA, the arc sits 23 feet 9 inches away from the center of the basket at its apex, which translates to roughly 7.92 yards. In the corners, the line flattens out to a shorter distance of 22 feet, or 7.33 yards. For FIBA play, the arc is set at 22 feet 1.75 inches, equal to about 7.38 yards.
The Free Throw Line and Key
The free throw line sits 15 feet away from the backboard's front face, which is exactly 5 yards. This line marks the end of the key, or the paint. The lane itself is 16 feet wide in the NBA (5.33 yards) and 4.9 meters (about 5.36 yards) in FIBA competition. When a player stands at the charity stripe, they're standing precisely five yards from the rim, trying to sink a shot under extreme defensive fatigue.
Half-Court and Center Circle
The center circle has a radius of 6 feet, meaning it spans 12 feet across—or 4 yards wide. The mid-court line divides the 31.33-yard length cleanly in half, giving each team roughly 15.66 yards of territory to defend once they cross over.
Why Court Dimensions Matter for Strategy and Design
Spacing dictates modern basketball strategy. Coaches often talk about floor balance, and looking at the court in yards illustrates why spacing is so tight. On a 16.67-yard-wide floor, five offensive players and five defenders must squeeze into lanes, pick-and-roll pockets, and weak-side corners.
When architects plan a new gymnasium, they don't just account for the 31.33 by 16.67-yard playing surface. Safety run-off areas are mandatory. Governing bodies require a buffer zone of at least 3 to 10 feet around the outer boundary lines. This means the actual room required for a safe installation expands well beyond the base court measurements.

Common Mistakes When Converting Court Sizes
People often trip up on court conversions due to mixing metric and imperial units. Here are a few errors to avoid:
- Forgetting the three-foot rule: A common slip is dividing feet by four instead of three when estimating yards. Always divide linear feet by three.
- Confusing meters and yards: FIBA uses metric dimensions (meters), which are close to yards but not identical. One meter equals roughly 1.09 yards.
- Ignoring run-off zones: Mistaking the inner playing lines for the total floor footprint leads to cramped gym designs. Always add the safety buffer.
Frequently Asked Questions
How many yards is a full basketball court?
A standard NBA or college basketball court is 31.33 yards long and 16.67 yards wide. High school courts are slightly shorter at 28 yards long by 16.67 yards wide.
How far is the three-point line in yards?
In the NBA, the three-point line is roughly 7.92 yards away from the basket at the top of the key, and about 7.33 yards away in the corners.
What is the distance of a free throw in yards?
The free throw line is located 15 feet from the backboard, which equals exactly 5 yards.
Why are international basketball courts smaller than NBA courts?
International courts follow FIBA rules measured in metric units (28 meters by 15 meters). The NBA uses imperial measurements (94 feet by 50 feet), making the professional American court roughly two feet longer than an international court.
