What match formats are used at Masters tournaments?

Question

Accepted Answer

The tournament committee chooses the format for each event from the ITF's permitted list and must publish it on the fact sheet before the entry deadline.

Singles

Grade	Best of 3 tie-break sets	2 sets + 10-point match tie-break	2 short sets + match tie-break
World Championships	All ages except 80+ to 90+	Only 80+ to 90+	Not permitted
MT700 and MT1000	All ages except 80+ to 90+	Only 80+ to 90+, or 30+ to 45+ events played over 3 days or fewer	Not permitted
MT200 and MT400	All ages except 80+ to 90+	All ages	Not permitted
MT100	All ages except 80+ to 90+	All ages	30+ to 60+ only, in events over 3 days or fewer

Usually one singles match a day; up to two a day is allowed in some formats and grades for 30+ to 60+ events.

Doubles at MT700, MT1000 and World Championships: best of three tie-break sets (except 80+ to 90+) or two sets plus a 10-point match tie-break, with up to two doubles a day.
