How are WTA singles and doubles matches scored?

Under the 2026 WTA Rulebook:

• Singles (main draw and qualifying): best of three tie-break sets.
• Doubles (main draw): best of three sets with No-Ad scoring in the first two sets and a 10-point match tie-break as the third set.
• There is no rest period before the final set except when the Extreme Weather Condition Rule is in effect.
• The WTA has the right to authorize alternative scoring systems at WTA tournaments.

This is the WTA rule for women's events. The men's ATP rules were not checked for this guide.
