Cricket Series Formats — Test Series, ODI Series and T20I Series Explained
International cricket is organised into series between two nations. Learn how Test series, ODI series, and T20I series are structured, how long they last, and what determines their scheduling.
In international cricket, bilateral series — two nations playing each other in a fixed number of matches — are the backbone of the international calendar. Series vary in length depending on format, the ICC's Future Tours Programme (FTP), and commercial arrangements between the two cricket boards. Most bilateral tours include a combination of Test matches, ODIs, and T20Is.
Test Series
Test series typically consist of 2–5 matches. The Ashes (England vs Australia) is a 5-Test series — the longest and most prestigious bilateral Test competition. Most series between other nations are 2 or 3 Tests. A series is won by the team that wins more Tests; if equal numbers are won, the series is drawn. Test series contribute to World Test Championship standings, making each match carry ICC ranking implications.
ODI and T20I Series
ODI series are usually 3 or 5 matches. A 5-match series produces a definitive winner even if results end 2-2 going into the final game. T20I series are increasingly 3, 4, or 5 games. ODI series between top nations contribute to the ICC Men's Super League qualification pathway for the ODI World Cup.
Future Tours Programme
The ICC's Future Tours Programme (FTP) is a master schedule of international cricket spanning multiple years. It determines which teams visit which countries, in what format, and for how long. The FTP protects the financial stability of smaller cricket boards by guaranteeing them visits from major cricketing nations.
