Equal Playing Time Calculator
How to share a game fairly across a squad — the minutes each player should get, how many substitution windows that takes, how long each stint is, and how many players sit out at any moment.
A game has a fixed number of player-minutes: players on the field times the minutes.
How the equal playing time calculator works
A game has a fixed number of player-minutes: players on the field times the minutes. Divide by the squad and everyone's fair share appears — which is less than the whole game whenever the squad is bigger than the team. Rotating in equal stints at regular intervals delivers it: the number of windows is the squad over the players on the field, rounded, and each stint is the game over that.
Formula: minutes each = on-field × game minutes / squad; stint = game / windows; sitting out = squad − on-field
Worked examples
| Inputs | Minutes per player | Note |
|---|---|---|
| 14 in the squad, 11 on the field | 55 | 55 minutes each |
| A fixed goalkeeper | 53.8 | the rest share 10 places |
| A big squad of juniors | 17.5 | under half a game each |
FAQFrequently asked questions
How do I give everyone equal time?
Work out the minutes each player is owed — on-field places times game length over the squad — then rotate in equal stints so each player's time on the bench adds up to the same.
How many substitution windows?
Roughly the squad divided by the players off at any time, so that everyone has been off once when the rotation completes. Round to what the sport's rules allow.
What about the goalkeeper?
Many junior competitions keep the keeper on for a half or a game. Fixing one position shares the remaining minutes among the rest.
Is equal time the right goal?
In junior and social sport, yes — development and enjoyment depend on playing. In competitive senior sport the coach picks; this page still says what fairness would cost.
What if the squad is too big?
Below about half a game each, players lose rhythm and interest. Two teams, or a rotation across matches rather than within one, works better.
