Introduction
If you are new to cricket, you may have heard commentators talk about an over, such as "10 overs completed" or "the team needs 40 runs in the last four overs." Understanding this term is essential for following a cricket match.
An over is a set of legal deliveries bowled by one bowler from one end of the pitch. In standard modern cricket, an over consists of six legal balls. After an over is completed, another bowler usually bowls the next over from the opposite end.
Overs help determine how much of an innings has been completed, how quickly a team is scoring, and how much time or how many deliveries remain in limited-overs matches.
How Many Balls Are in an Over?
In standard cricket, **one over contains six legal deliveries**.
For example, if a bowler delivers six legal balls without any no-balls or wides, the over is complete.
However, illegal deliveries such as wides and no-balls generally do not count toward the six legal balls. The bowler must deliver additional legal balls to complete the over.
### Example of an Over
Imagine a bowler delivers the following:
- Ball 1: One run
- Ball 2: No run
- Ball 3: Four runs
- Ball 4: Wide
- Ball 5: Two runs
- Ball 6: No-ball
- Ball 7: One run
- Ball 8: No run
In this example, the wide and no-ball do not count as legal deliveries. The over is completed only after six legal balls have been bowled.
The total runs scored during an over can vary considerably. A team might score no runs from an over, or it might score many runs through boundaries, running between the wickets, and extras.
What Happens After an Over?
After six legal deliveries, the over ends. The next over is bowled from the opposite end of the pitch, and a different bowler usually takes over.
A bowler cannot normally bowl two consecutive overs in the same innings. Teams rotate their bowlers according to the match format, conditions, and strategy.
The change of ends also means the batters face deliveries from the other side of the pitch. This can affect line, length, swing, spin, and the fielding team's approach.
How Many Overs Are There in Different Cricket Formats?
The number of overs depends on the format of the match.
| Cricket Format | Overs per Team |
|---|---|
| Test cricket | No fixed limit in the traditional format |
| One Day International (ODI) | Usually 50 overs |
| Twenty20 (T20) | Usually 20 overs |
| T10 cricket | Usually 10 overs |
### Overs in Test Cricket
Test cricket is played over a maximum of five days under standard playing conditions. Each team generally has two innings, and there is no fixed limit of 50 or 20 overs per innings.
Minimum-over requirements may apply to the bowling side within scheduled playing time, subject to playing conditions and interruptions.
### Overs in ODI Cricket
A standard One Day International match gives each team a maximum of 50 overs in a full innings.
The team batting first tries to set a competitive total. The team batting second attempts to reach that target before losing all its wickets or exhausting its available overs.
Rain or other interruptions may reduce the number of overs available under the applicable playing conditions.
### Overs in T20 Cricket
In a standard T20 international match, each team usually has a maximum of 20 overs.
Because the innings are shorter, teams often try to score quickly. Batters may attack more frequently, and bowlers need to balance wicket-taking opportunities with controlling the scoring rate.
The exact number of overs can be reduced if a match is interrupted, according to the competition's rules.
What Does 10 Overs Mean in Cricket?
When a commentator says that a team has completed 10 overs, it generally means that 60 legal deliveries have been bowled during that innings.
For example, if a team has scored 80 runs after 10 overs, its run rate is:
Run rate = Total runs ÷ Overs completed
80 ÷ 10 = 8 runs per over.
This means the team has scored an average of eight runs per over.
In a full 20-over innings, a team scoring at that rate would reach 160 runs if it maintained the same rate for all 20 overs. This is a mathematical projection, not a guarantee of the final score.
How Are Overs Shown on a Cricket Scoreboard?
Cricket scoreboards commonly show overs using a format such as `12.3`.
This does **not** mean 12.3 decimal overs. It means 12 completed overs and three legal balls in the current over.
Since an over contains six legal balls:
- `5.0` means five completed overs.
- `5.1` means five overs and one legal ball.
- `5.4` means five overs and four legal balls.
- `6.0` means six completed overs.
This notation is important when calculating run rates and checking how many legal deliveries remain.
For example, a score of 75 runs after `10.0` overs gives a run rate of 7.5 runs per over. If the score is 75 after `10.3` overs, the calculation must use 10.5 overs in decimal arithmetic, because three balls represent half an over.
Why Are Overs Important in Cricket?
Overs influence several important aspects of a match.
### 1. Scoring Rate
The number of runs scored per over helps show whether a batting team is scoring quickly enough to build a strong total or chase a target.
### 2. Bowling Strategy
Captains decide which bowlers should bowl at different stages of the innings. Some bowlers may be used early, while others are saved for the middle overs or the final overs.
### 3. Batting Strategy
Batters may change their approach depending on how many overs remain. They might prioritize building partnerships early or increase their attacking shots toward the end of a limited-overs innings.
### 4. Match Progress
Overs provide a simple way to track progress. In a 20-over match, for example, completing 15 overs means that only five scheduled overs remain in a full innings.
Conclusion
An over in cricket is a set of six legal deliveries bowled by one bowler from one end of the pitch. Wides and no-balls generally require additional deliveries because they do not count toward the six legal balls.
Overs are central to understanding scoring rates, innings progress, and bowling strategies. Whether you are watching Test cricket, a 50-over ODI, or a fast-paced T20 match, learning how overs work makes the game easier to follow.

### How many balls are in one over in cricket?
A standard over contains six legal deliveries. Wides and no-balls generally do not count toward those six deliveries.
### Can an over have more than six balls?
