Twelve players on two courts is one of those club setups that looks manageable until you try to run it cleanly. Eight players are active at a time, which means four are always waiting. That is not automatically a problem, but it does mean your rotation has to be deliberate.
The good news is that twelve on two courts can work very well if the host treats sit-outs as part of the design instead of an afterthought.
Start with the right expectation
With twelve players and two courts, every round leaves four players off. The real fairness target is equal opportunity across the full session, not every player participating every round.
Use medium slot lengths unless the group is extremely quick
Because four people are waiting each round, very long slots can feel punishing. For most groups, 18 to 20 minutes is the sweet spot.
Track the waiting pool explicitly
You cannot run this format well by memory alone. The four players who sat last round should be the first candidates to come in next.
- Round A: four players sit.
- Round B: those four move forward first.
- Round C: check who has now waited least and most, then balance again.
Vary both teammates and opponents
Because the active pool is only eight players at a time, repetition risk is higher than people think. Good hosts watch not just who is playing, but who keeps being paired together.
Set the tone early with a clean first two rounds
The first two rounds matter a lot because everyone can see whether the waiting burden is being shared. Visible fairness buys you breathing room for the rest of the evening.
Tell players what system you are using
Check the arithmetic before choosing the session length
A two-hour session with 20-minute slots gives you six complete rounds. Each round has eight active positions, so the evening contains 48 player-spots. Divide 48 by 12 players and the clean target is four rounds per person. That also means each player should expect approximately two sit-outs.
If you use 25-minute slots instead, only four complete rounds fit into two hours, leaving 32 player-spots. Eight players can receive three rounds while four receive only two unless you extend the session or shorten a round. Nothing is wrong with the rotation; the capacity simply does not divide evenly. Explaining that arithmetic prevents the host from being blamed for geometry.
A practical six-round review
You do not need to prescribe every matchup in advance, but you should be able to audit the overall pattern:
- After Round 2, every player should have appeared at least once.
- After Round 3, no player should have taken a second sit-out while another has taken none.
- By the final round, total appearances should differ by no more than the unavoidable remainder created by capacity.
- Back-to-back partner repeats should be exceptions rather than the default.
What to do when one player leaves early
Do not keep an empty name in later rounds. Remove the player at the next slot boundary and regenerate the remaining portion if necessary. Eleven players still fill two courts, but only three wait each round. Preserve completed rounds as your record and treat the updated schedule as a new plan from that point forward.
Where MyCourtSlot helps
MyCourtSlot is useful in this exact kind of constrained session because it gives the host a readable rotation draft quickly and makes edits easier when attendance changes or a late player appears.
