Looking to build or remark your tennis courts? It can be pretty difficult trying to remember all the different tennis court sizes required for every line and area. That’s why Net World Sports has created a comprehensive, yet simple guide, looking at all the facts and figures required for tennis court dimensions to create a regulation tennis court size exact to the decimal place. For any newbies looking to create a court, we’ve highlighted a few key areas needed when marking:

Tennis court lines labeled
  1. Singles Sideline – this is the outer edge of the court during singles competition.
  2. Baseline – the furthest line back at each end of a tennis court. This is where players will serve from and the line is divided by a centre mark. Standing at the centre will provide maximum coverage for serving and returns.
  3. Doubles Sideline – the outer edge of the tennis court during doubles competition.
  4. The Tennis Net – always down the centre of the court. This can be adjusted using the levers on the tennis post.
  5. Service Box – this is the area the ball must land in when serving. The ball must be served into the opposite service box from the side you are serving from and alternates after each point.
  6. Baseline Centre Mark – this signifies the central point of the baseline. Players serve from either side of this point, placing the ball into the service box the opposite side.
