Wnba playoffs best of 3 or 5

On 28 September 2026, the WNBA officially confirmed a major structural change to its postseason format, announcing that the first round of the playoffs will transition from a best-of-three series to a best-of-five series starting in the 2027 season. This decision follows extensive discussions among league officials, team owners, and the players' association regarding the desire to provide more competitive opportunities and increase the intensity of the opening round. Previously, the league had utilized a best-of-three format for the first round since 2022, which often resulted in quick exits for lower-seeded teams. By expanding the series, the WNBA aims to mirror the format used in the semifinals and finals, ensuring that every stage of the postseason requires a more robust demonstration of team depth and resilience. League Commissioner Cathy Engelbert noted that the change is part of a broader strategy to capitalize on the record-breaking viewership and engagement levels seen throughout the 2026 season, ultimately providing fans with more high-stakes basketball during the most critical time of the year.
