A Test match has no over limit per innings (with 90 overs bowled per day). An ODI has 50 overs per side. A T20 has 20 overs per side. One over consists of 6 legal deliveries bowled by a single bowler. The number of overs in each format directly affects how long a match lasts, how teams plan their innings, and how aggressively they play.
Overs by Format
| Format | Overs per Innings | Total Match Overs (max) | Overs per Day |
|---|---|---|---|
| Test | Unlimited | ~450 (5 days × 90) | 90 |
| ODI | 50 | 100 | All in one day |
| T20 | 20 | 40 | All in one day |
| The Hundred | 100 balls (not overs) | 200 balls | All in one day |
What Is an Over?
An over is a set of 6 legal deliveries bowled from one end of the pitch. After each over, a different bowler bowls from the opposite end. No balls and wides do not count as legal deliveries, so an over can have more than 6 actual balls bowled.
For example, if a bowler bowls 2 no balls and 1 wide during an over, they will actually deliver 9 balls but only 6 count toward completing the over. Those extras also add runs - a no ball gives 1 run plus a free hit in limited-overs cricket.
Test Cricket: Unlimited Overs, 90 Per Day
In Test cricket, there is no cap on how many overs a team can bat. A side can bat for an entire day (90 overs) or even multiple days if they choose. The only limits are the 5-day match duration and the team getting bowled out (all 10 wickets falling).
Each day of Test cricket is divided into 3 sessions:
- Morning session: ~30 overs
- Afternoon session: ~30 overs
- Evening session: ~30 overs
If the bowling side falls behind the required over rate (90 per day), the final session is extended until the overs are completed. Slow over rates can also result in match bans and fines for the bowling team's captain.
From experience: In multi-day cricket, the overs count matters more than people realise. As a batter, when you have faced 100+ balls and the bowlers are into their 25th-30th over, they tire. The ball softens. That is when you cash in. Understanding overs is not just numbers - it is reading the game situation.
ODI Cricket: 50 Overs Per Side
Each team gets exactly 50 overs to bat unless they are bowled out earlier. The 50 overs are split into 3 powerplay phases that control how many fielders can stand outside the 30-yard circle.
A typical ODI innings scoring pattern:
- Overs 1-10 (Powerplay 1): Aggressive start, 5-7 runs per over
- Overs 11-35 (Middle overs): Consolidation, 4-6 runs per over
- Overs 36-50 (Death overs): Full attack, 8-12 runs per over
Individual bowlers can bowl a maximum of 10 overs in an ODI (20% of the innings). This means a captain needs at least 5 bowling options to cover 50 overs.
T20 Cricket: 20 Overs Per Side
The shortest international format gives each team just 20 overs. Individual bowlers are limited to 4 overs each, so teams need a minimum of 5 bowlers.
The 6-over powerplay at the start is where teams try to score quickly with only 2 fielders allowed outside the circle. After the powerplay, the fielding side can spread the field, making boundaries harder.
A good T20 score is format-dependent: on flat pitches, teams target 180+. On tricky surfaces, 150 can be competitive. The entire match wraps up in about 3 hours.
How Overs Affect Bowling Strategy
| Phase | Test | ODI | T20 |
|---|---|---|---|
| New ball | Swing/seam attack for early wickets | Same, but more aggressive | Pace and bounce, aim for powerplay wickets |
| Middle overs | Build pressure, spin dominates | Contain, take wickets through dot balls | Spinners bowl bulk of middle overs |
| Death overs | Not applicable | Yorkers, slower balls, wide lines | Same but even more high-pressure |
Over Rate Rules and Penalties
The ICC enforces minimum over rates across all formats. If a team bowls too slowly, consequences include:
- Test cricket: Extra fielder inside the circle in the final hour if behind rate
- ODIs/T20s: An extra fielder must come inside the 30-yard circle for every over behind the minimum
- Captain penalties: Fines of 20-40% of match fees and potential suspension
Conclusion
The number of overs defines everything about a cricket match - the pace of scoring, the bowling strategy, and how long the game lasts. Test cricket's unlimited overs reward patience and endurance. ODI's 50 overs demand pacing and acceleration. T20's 20 overs force instant aggression. Once you understand how overs shape each format, you will start reading the game the way players and commentators do.
FAQs
How many balls are in a cricket over?
6 legal deliveries. No balls and wides are re-bowled and do not count toward the 6.
Can a Test match finish in less than 5 days?
Yes. If both teams complete their innings before day 5, the match ends early. Some Tests have finished in under 2 days.
Why do bowlers have an over limit in ODIs and T20s?
To prevent one dominant bowler from bowling the entire innings. The 10-over limit (ODI) and 4-over limit (T20) force teams to use at least 5 bowlers.
What happens if overs are lost to rain?
The match is reduced using the Duckworth-Lewis-Stern (DLS) method, which recalculates target scores based on remaining overs and wickets.
