Sports Court Marking with Competition-Grade Precision
Every millimetre matters on a sports court. Tennis baselines must be exactly 23.77 metres apart. Basketball keys need precise arc radii. Netball goal circles need an exact 4.9 metre radius. We've marked over 800 courts since 2009 for clubs, schools, councils, and private facilities. Laser-measured, correctly dimensioned, certified for competition.

What is Precision Matters on Every Sports Court?
Quick answer: Line Marking Australia marks tennis, basketball, netball and multi-sport courts to official dimensions, such as 23.77 m by 10.97 m for doubles tennis and 28 m by 15 m for basketball. We measure twice with lasers, mark chalk pilot lines for you to approve, then paint, so lines are accurate to the millimetre before anything is permanent.
We learned this the expensive way. Back in 2018, a tennis club in Moorabbin asked us to remark their championship court. We were 35mm out on one baseline. Doesn't sound like much, right? Wrong. The court failed club certification. We had to grind off everything and redo the entire court at our cost. Around $4,500 gone.
That expensive lesson taught us our current process: measure twice with lasers, mark pilot lines in chalk, get client approval, then commit to paint. We haven't had a measurement issue since.
Sports court marking isn't like carpark marking. Tolerances are millimetres, not centimetres. A tennis court is 23.77m x 10.97m for doubles, and 8.23m wide for singles. Basketball courts are 28m x 15m with precise arc radii. Netball requires 30.5m x 15.25m with specific circle dimensions. We use laser measurement and string lines to guarantee accuracy.
Multi-sport courts are our specialty. Overlaying tennis, basketball, and netball on one surface requires careful colour coordination so players can distinguish their lines during play. We've developed colour schemes that work for multi-sport use while meeting each sport's requirements.

Tennis typically uses white lines on green or blue surfaces. Basketball uses contrasting colours for keys and lines. Netball often uses red or orange. For multi-sport, we discuss options to ensure each sport is clearly distinguishable while maintaining good aesthetics.
