2019 WTA Tour

The 2019 WTA Tour was the elite professional tennis circuit organised by the Women's Tennis Association (WTA) for the 2019 tennis season. The 2019 WTA Tour calendar was composed of the Grand Slam tournaments (supervised by the International Tennis Federation (ITF), the WTA Premier tournaments (Premier Mandatory, Premier 5, and regular Premier), the WTA International tournaments, the Fed Cup (organized by the ITF), and the year-end championships (the WTA Tour Championships and the WTA Elite Trophy). The Hopman Cup, organized by the ITF, also is included but did not distribute ranking points.

Prior to the season, the WTA announced usage of a shot clock at all Premier events. Players had a minute to get on court, five minutes to warm up, and one minute to start the match. The time allotted to players in between points was increased from 20 to 25 seconds. Finally, players were allowed only one toilet break in a match.
