Basketball court sizes & dimensions
Regulation basketball numbers (FIBA, NBA, 3×3) and the five backyard sizes that actually get built — with real dimensions, areas and prices.
Basketball is the most-built backyard court, and the first question is always the same: how big should it be? Here are the regulation numbers, then the sizes people actually build.
| Standard | Dimensions |
|---|---|
| FIBA full court | 28 m × 15 m |
| FIBA half court | 14 m × 15 m |
| FIBA 3×3 | 15 m × 11 m |
| NBA full court | 28.65 m × 15.24 m |
| Key (FIBA) | 4.9 m wide × 5.8 m deep |
| Free-throw line | 5.8 m from the baseline |
| 3-point arc | 6.75 m radius (FIBA) · 7.24 m (NBA) |
| Rim height | 3.05 m — the one number that never changes |
| Run-off (FIBA competition) | 2 m of clear space around the playing surface — on top of the numbers above |
What actually fits a backyard
Almost nobody builds a full regulation court at home — and they don't need to. A half court with the key and free-throw line covers practice; add depth for the 3-point arc and you've covered real games. These are our five ready-made basketball sizes, smallest to largest — every dimension is live from the court engine, including the edging:
| Court | Overall size | Area | Price |
|---|---|---|---|
| Driveway Basketball Court | 4.12 m × 5.04 m | 20.8 m² | $1,017 |
| Free-Throw Basketball Court | 5.95 m × 9.00 m | 53.6 m² | $2,624 |
| 3-Point Half Court | 8.08 m × 10.22 m | 82.6 m² | $4,048 |
| Large Half Court (3×3 Regulation) | 15.10 m × 10.22 m | 154.3 m² | $7,558 |
| Full Basketball Court | 16.31 m × 29.42 m | 480.0 m² | $23,519 |
The 3-Point Half Court is the size most families land on — deep enough for the arc, compact enough for a normal backyard. If you're between sizes, the designer builds tile-by-tile, so any size in between is yours.
Reading the numbers
Every court is built from 304.8 mm (1 ft) tiles, so dimensions step in whole tiles — no cutting. The figures above include the bevelled edging. In the designer, tap Measurements to see every dimension overlaid on your exact court.
Planning for a hoop
Most adjustable hoops overhang 0.9–1.2 m from the pole onto the court, so the pole and its concrete footing sit behind the playing surface — never on the tiles. If you're pouring a new slab, pour the hoop footing at the same time (your hoop's manual specifies the footing size), positioned so the backboard hangs over the baseline.
