Test vs ODI vs T20 — How Cricket's Three Formats Compare
Cricket's three main formats — Test, ODI, and T20 — differ in length, rules, skills and atmosphere. A side-by-side guide to what changes between the longest and shortest forms.
Cricket has three major international formats, plus a growing list of franchise variants. Each shares the basic mechanics — bat, ball, two innings per side or one — but the length, pace, and skill emphasis differ dramatically.
At-a-glance comparison

|---|---|---|---|
| Length | Up to 5 days | 1 day (~8 hours) | ~3 hours |
| Innings per side | 2 | 1 | 1 |
| Overs per innings | Unlimited (until 10 wickets) | 50 | 20 |
| Ball colour | Red (day) / Pink (D/N) | White | White |
| New balls | 1 per innings; new ball after 80 overs | 1 per innings | 1 per innings |
| Result options | Win / Draw / Tie | Win / Tie / No Result | Win / Tie (Super Over) |
| Powerplay | No | Three phases | First six overs |
| Free hit | No | Yes | Yes |
| DRS reviews per side | 3 per innings | 2 per innings | 2 per innings |
Test cricket — the long form
A Test is a five-day match contested across two innings per side. There's no over limit per innings — a side bats until it's bowled out or declares closed. Sessions are split by lunch and tea breaks. The pitch deteriorates across the five days, and fourth-innings chases on a turning surface are among the hardest tasks in the sport.
Test cricket rewards patience and stamina. Top scores often come from batters absorbing 200+ deliveries; bowlers chip away at the same batter for an entire session. A win demands taking 20 wickets across two innings.
ODIs — the original limited-overs game
Each side bats one innings of 50 overs. The format was introduced in the 1970s and remains the home of the ICC ODI World Cup. ODIs have powerplays in three phases (1-10, 11-40, 41-50) that shape how teams pace an innings. A par score on a flat pitch sits around 280-310; pitches in the subcontinent sometimes produce totals above 400.
ODI batters typically build through ten-over phases; bowlers conserve overs (max ten per bowler) and pick attacking phases.
T20s — the short and explosive form
Twenty overs per side, finished in roughly three hours. T20 is the format the franchise leagues — IPL, PSL, BBL, The Hundred, CPL — built on. Power-hitting dominates batting; bowlers focus on death-overs skills like yorkers and slower balls. Tactical depth is real, just compressed: every ball is worth roughly 1.4% of a side's chase.
Common ground
- Same field — 22 yards from stump to stump, 30-yard circle inside the boundary.
- Same dismissals — bowled, caught, LBW, run out, stumped, hit wicket, obstructing the field, handling the ball, timed out.
- Same fundamental skills — bat, ball, fielding — though each format rewards different combinations.
Which format does a fan choose?
A casual fan often starts with T20 — short, explosive, easy to consume. ODIs add depth and historical weight (the ODI World Cup is cricket's biggest tournament). Test cricket rewards the patience to follow a five-day arc, and remains the format the players themselves rank as the truest measure of skill.
Frequently asked questions
How many overs are in a Test match?
There's no fixed number. A Test is played in two innings per side with no over limit — a side bats until bowled out or declares. A typical Test runs 350-450 overs total across five days.
Why do ODIs use white balls and Tests use red?
Red balls swing more for longer in daylight but are harder to spot under floodlights. White balls are more visible under lights for the night-cricket formats. Pink balls bridge the gap for day-night Tests.
Can a Test end in a draw?
Yes. If neither side bowls the other out twice in the allotted five days, the match is a draw. This is different from a tie, which is when the side batting last is bowled out with the scores level.
How many fielders outside the circle in each format?
T20: two during the six-over powerplay, then five for the rest. ODI: two in phase one (overs 1-10), four in phase two (11-40), five in phase three (41-50). Test: no restrictions — the captain sets any field.
