Home and Driveway Basketball Half-Court Marking

What are the standard half court basketball dimensions in Australia?

Half court basketball dimensions in Australia follow FIBA standards: 14 metres wide by 15 metres deep, with 50 mm line widths. Home and driveway courts are often scaled to fit available space, but the goal is to retain a single key, three-point arc, and clear, durable markings.

Most Aussie homes don’t have room for a full-size half court, but the core elements—free throw lane, three-point arc, and centre circle—can be adapted to suit. We’ve marked everything from tight driveways to backyard pads, always working to the space while keeping the game playable and enjoyable.

Element	FIBA Half Court
Total size	14 m x 15 m
Line width	50 mm
Three-point arc	6.75 m from the basket (full size)

Can you scale half court basketball dimensions for home or driveway courts?

Yes, half court basketball dimensions are often scaled for home or driveway courts in Australia. The key is adapting the core features—key, three-point arc, and line width—so they fit without losing playability. Most home courts aren’t regulation size, and that’s perfectly fine for casual games.

We assess each site and discuss your goals: shooting practice, 1-on-1, or family games. If you’ve only got a 7 x 8 metre slab, we’ll proportion the markings so the key, free throw line, and three-point arc feel right for your space. The three-point arc, for example, might be a little closer if you’re tight on room, but we’ll keep it playable and visually balanced.

• Measure your available space first.
• Decide if you want a full or partial three-point arc.
• Prioritise the key and free throw line for shooting drills.

What features should every home half court include?

A home half court should feature a key (free throw lane), free throw line, three-point arc (full or partial), and clear boundary lines. These provide the basic zones for shooting, layups, and casual competitive play, even if the court isn’t full FIBA size.

We always recommend including the free throw line at a scaled distance if you’re short on space, as this is a common shooting spot. Even with a compact driveway, adding the key and a partial arc gives you more practice options. For larger backyards, we can lay out a proper three-point arc and a full rectangular key.

• Key (rectangle/lane area)
• Free throw line
• Three-point arc (scaled or full)
• Sidelines and baseline

How do you mark a basketball half court on a home driveway?

Marking a basketball half court on a driveway involves measuring and snapping chalk lines for the key features, then applying 50 mm wide line marking paint. Preparation is crucial—clean the surface, map out your dimensions, and check for drainage slopes or obstacles before painting.

We start by confirming your available space and desired layout. Using a tape, string, and chalk, we outline the rectangle for the court, the key, and arc. For the arc, we use a fixed-point string method to keep it even from the basket. Once the lines are mapped, we mask the edges and apply durable line marking paint—typically a UV-stable acrylic for concrete or bitumen driveways.

1. Clean the surface thoroughly.
2. Mark out key measurements.
3. Snap chalk lines for guides.
4. Mask for crisp edges.
5. Paint with 50 mm wide lines.
6. Allow to dry thoroughly.

What paint and materials give the best finish for home basketball courts?

For home basketball courts in Australia, use UV-stable, slip-resistant acrylic line marking paint at 50 mm width. Durable, purpose-made sports coatings withstand sun, rain, and regular play. Preparation is as important as the paint: a clean, dry slab ensures adhesion and sharp lines.

We don’t recommend ordinary house paint—it wears fast and can get slippery. For driveways, we use trade-grade sports line paint, matched to your surface (concrete or bitumen). If you want colour fill zones (like a painted key), we use the same tough acrylic in contrasting colours. Cure time is typically overnight in good weather, but always check the manufacturer’s guidelines.

• UV-resistant acrylic sports paint
• 50 mm line width (as per FIBA)
• Non-slip additives available for extra safety
• Masking tape for sharp edges

How do you scale the three-point arc on a tight home court?

You can scale the three-point arc on a home court by reducing its radius to suit your space, keeping it visually in proportion with the key and overall layout. The full-size FIBA three-point arc is 6.75 metres from the hoop, but many Aussie driveways require a smaller arc—just make sure it’s playable and even.

To map out a scaled arc, anchor a string at the basket’s centre point and mark the arc’s curve at your chosen distance, checking clearances at the baseline and sidelines. If your court is very short, you might use a 4.5 or 5 metre arc instead. The key is consistency—make sure the arc is the same distance at all points from the ring.

Space Available	Arc Radius
Full FIBA (14 x 15 m)	6.75 m
Medium (10 x 10 m)	~5.5–6 m
Compact (7 x 8 m)	~4–5 m

What does the Australian Standard say about basketball court marking?

Australian basketball court marking follows FIBA guidelines for competitive courts, but home and driveway half courts can be scaled. The key is clear, 50 mm wide lines and proportionate layout. For public facilities or schools, refer to Standards Australia for compliance (Standards Australia).

For private use, it’s all about function and safety. If you’re marking a court for a strata complex or a shared community area, check with your local council or refer to AS/NZS 2890.1 for access and layout standards. For home driveways, focus on clear lines, non-slip paint, and enough space around the markings to prevent trips or falls.

• Follow FIBA for full-size layouts
• Scale for home use, maintaining proportions
• Use 50 mm wide lines
• Check for surface safety—see Safe Work Australia

Common mistakes when marking home driveway basketball courts

The most common mistakes with home driveway basketball courts are poor surface prep, incorrect scaling, wobbly three-point arcs, and using house paint instead of proper line marking paint. These errors can make the court hard to play on and cause the lines to fade or chip quickly.

We’ve seen jobs where the arc is too close to the key, making shots awkward, or where someone’s used wall paint, which peels in weeks. Skipping cleaning or not checking for slopes means paint won’t bond or wears unevenly. Masking tape is your friend for sharp lines—but don’t leave it on too long after painting, or you’ll pull up fresh paint.

• Not scaling the arc/key to fit the space
• Poor surface cleaning (dust, oil, moss)
• Wrong paint type (slippery, fast-wearing)
• Crooked or uneven lines due to freehand work
• Forgetting drainage or driveway slope

Step-by-step: How Line Marking Australia marks a home half basketball court

We follow a proven process for every home half court, whether it’s a fresh slab or an old driveway. Preparation, precision, and the right materials are key for a sharp, long-lasting result. Here’s how we do it:

1. Site Inspection: Measure available space, assess surface, note any hazards or obstacles (drains, steps).
2. Layout Planning: Sketch scaled court on paper, decide on arc radius and key size.
3. Surface Prep: Pressure clean, degrease, and dry the area. Repair cracks if needed.
4. Mark Out: Snap chalk lines for the rectangle, key, free throw line, and arc (using string anchored at the hoop).
5. Masking: Tape along all lines for crisp edges.
6. Painting: Apply two coats of UV-stable acrylic sports paint, 50 mm wide. Remove tape after partial cure.
7. Final Check: Inspect for coverage, touch up as needed. Advise on cure time before play.

We recommend not playing on the new markings for at least 24 hours, depending on weather. For more how-to, see our basketball court guide.

What to check before and after marking your basketball court

Before marking, check your driveway or slab for space, surface condition, and slope. After marking, inspect the lines for clarity, consistency, and durability. Make sure everything’s cured and lines are safe (non-slip). If you’re DIY-ing, double-check all measurements before you paint.

We also check that there’s enough space behind the baseline for layups and no trip hazards (like raised expansion joints). After painting, walk the court to confirm the lines are visible from all angles and the paint’s not slippery. For shared spaces or rentals, get approval before starting.

• Measure space (length, width, clearance)
• Check for cracks, moss, oil stains
• Confirm measurements before painting
• Inspect dry lines for sharpness and colour
• Test surface grip (especially in wet weather)

How does a home half court compare to a professional (FIBA) half court?

A home half court is usually smaller than a professional FIBA half court, which measures 14 x 15 metres. Home courts are scaled to the available space, but keep the key features: key, free throw line, and three-point arc. Professional courts have strict dimensions, while home courts are about making the most of what you’ve got.

If you want a training or coaching court, we can mark to FIBA spec if you have the space. For most families, a scaled-down court gives plenty of play value. The main compromise on home courts is the distance of the three-point arc and the width of the key, which can be reduced to fit the slab.

Feature	Home Half Court	FIBA Half Court
Overall size	Scaled to fit	14 x 15 m
Line width	50 mm	50 mm
Arc radius	Scaled	6.75 m
Key width	Scaled	Variable (per FIBA)
