The mantle of world No.1 in tennis is something every player aspires for but few ever achieve. 

When it comes to women’s singles, Serena Williams dominated for years, although younger players have since emerged to stake their claim for the crown.  

Aryna Sabalenka is the current gold standard, with Iga Świątek within striking distance.

Who is the world No. 1 in women’s tennis?

With the first grand slam of the year in the books, Aryna Sabalenka has held onto her number one ranking to start 2025, after making a third straight Australian Open final. 

But it was her opponent who made the most impressive leap, American Madison Keys jumping up seven spots into the top 10 off the back of a maiden grand slam title. 

Paula Badosa has also entered the top 10, while Iga Świątek remains the only other player within 1000 points of the top spot.

How do tennis rankings work?

Women’s tennis world rankings are calculated by the WTA, who award points based on a player’s performance at particular tournaments. 

The further a player progresses in a sanctioned event, the more points they will be awarded. 

Grand slams provide the most points with 2000 awarded to the winner and 1200 to the runner-up. 

Points picked up from each tournament last for one year with rankings updated each week. 

When are tennis rankings updated?

Both the ATP and WTA update their rankings every Monday when tournaments aren’t running. 

So, in general, you can expect weekly updates aside from when Grand Slams are being held.
