Apart from the main tennis court, you need space for run-off at the back of the court and also a run-off area at the side of the court to fence. In tournaments, there is also a need for space for the umpire, line judges, and ball boys/ girls. There may be other things also like a chair, camera and other equipment. All these things vary from tournament to tournament, like the space needed for the grand slams may be larger than the challengers.

Apart from the above-mentioned court dimensions, there is some smaller recommended tennis court dimension for the juniors (Aged 10 and under 10). International Tennis Federation has segmented these smaller courts into three groups.

  • Red”  – For juniors aged up to 8 years
  • Orange” – For 8 to 10 years
  • Green” – Advanced players aged between 9 to 10 years

Juniors under the “Green” stage, are recommended to play on a standard full-size court. Smaller courts are recommended only for the “Red” and “Orange” stages.

Categorization of Court According to Speed

Recently ITF has launched a court pace certification program and according to this program, the courts have been segmented into five pace categories. Slower courts offer high bounce and less speed and for that players get more time to play shots. In reverse, faster lawn tennis courts produce high speed and low bounce where the serve and volley strategy is more suitable.

Category 1Slow≤ 29
Category 2Medium-Slow30-34
