Standard Tennis Court Size

The ITF ensures that the dimensions of a tennis court are the same everywhere so that players don’t have to “adjust” their game depending on where they play. Imagine training on a shorter court and then suddenly facing a full-size one in a tournament. It would completely throw off your timing.
