Beyond the calculator
Run the whole competition in Crickslab. Fixtures, grounds, officials and the table all sit in one place and update themselves.
- Fixtures and standings generated for you
- Grounds, slots and officials in one calendar
- Every stat from every match, kept for good
How this was worked out
- 1Capacity4 days x 2 grounds x 2 per day = 16 matches
| Format | Matches | Per team | Days needed | Verdict |
|---|---|---|---|---|
| Single round robin | 28 | 7 | 7 | too many |
| Double round robin | 56 | 14 | 14 | too many |
| Knockout | 7 | 1 | 2 | fits |
| Two groups plus semis and final | 15 | varies | 4 | fits |
| Four groups plus quarters onward | 11 | varies | 3 | fits |
How the number is worked out
The formula
Capacity = days x grounds x matches per ground per day- capacity
- The total matches you can physically stage.
- round robin
- n x (n - 1) / 2 matches, where n is the number of teams.
- knockout
- n - 1 matches, because each one eliminates a side.
A worked example: eight teams over a weekend
Eight teams, four days, two grounds, and short enough matches to fit two on a ground per day.
- 1Capacity4 days x 2 grounds x 2 per day = 16 matches
- 2Single round robin8 x 7 / 2 = 28 matches, which does not fit
- 3Two groups plus semis and final12 group matches + 3 = 15, which fits
- 4Straight knockout7 matches, fits easily but gives four teams one match
A group stage plus semi finals and a final is the format that fits. A full round robin needs almost twice the capacity available.
Rules and edge cases
The situations that change the answer, and the ones most calculators get wrong.
Round robin grows fast, and organisers underestimate it
Six teams is 15 matches. Ten teams is 45. Twelve is 66. The count grows with the square of the field, so a format that works for a small competition becomes impossible two teams later. Check the number before promising a round robin.
Two matches on a ground in a day is a groundstaff question
It only works for shorter formats, and it depends on whether the square and the outfield can take the traffic. Assume one per ground per day unless you have asked, because the whole plan collapses if the answer is no.
A knockout gives half your field one match
For a club day or a youth festival that is usually the wrong shape. People have travelled to play cricket, not to watch one match and go home. A group stage guarantees everyone several matches and still finishes on time.
Uneven groups need care in the standings
Where the groups differ in size, teams in the smaller one play fewer matches and can earn fewer points. If the standings compare across groups, rank on net run rate or points per match rather than on the raw total.
Leave a reserve day or an over reduction plan
A format that uses every available slot has no room for weather. Either hold a reserve day or agree in advance how many overs each match drops to if the schedule slips.
Frequently asked questions
A single round robin needs n x (n - 1) / 2 matches for n teams. A knockout needs n - 1. A group stage plus playoffs sits between the two.
For tournament organisers
Plan the format here, run the competition in Crickslab
Once the shape is settled, Crickslab takes the fixtures, the grounds and the results and keeps the standings, statistics and live scores current without further admin.
