The World Curling Rankings system is designed to track and list the amount of success achieved by each member association of the World Curling Federation (WCF) in a given curling season. The system, which was implemented in December 2006, is similar to the ranking system used by FIFA. The events taken into account when calculating each nation's score include the Winter Olympics, the World Curling Championships, the European Curling Championships, and the Pacific Curling Championships. The system was developed by Patrick Hürlimann, who is a former Olympic champion and was the vice president of the WCF from 2010 to 2012.

The points are calculated for each nation based on performance during the last six curling seasons. Results in seasons prior to the current season are scaled by the following factors:
Points distribution
Points are allocated based on the final rankings of each nation at an eligible event.
International events
The points distributions are given for each event as follows:
Regional events
All nations that qualify for the World Curling Championships receive 50 points, regardless of final ranking in regional events, if applicable.
Nations in the European or Pacific Curling Championships that do not qualify for the World Championships receive less than 50 points. Based on their final ranking in the tournament, nations receive 49 or fewer points, in decrements of 1 point.
