Court Booking Math: Courts for 8, 12, 16 Players

Quick Answer: One court per four players if everyone plays at once: 8 players need 2 courts, 12 need 3, 16 need 4. With fewer courts people sit out, and the padel each person gets is your booked minutes times four, times your courts, divided by the number of players.

Every group booking decision comes down to one number: four. A padel court holds four people, and every format ever invented is a rule for deciding which four, and when it changes.

That makes court planning arithmetic rather than judgment — which is good news, because the arithmetic includes one result almost nobody expects about cost. Here is the whole calculation, format by format. For the formats themselves, padel formats by group size is the map.

The three formulas

Courts you can fill = players ÷ 4, rounded down. You cannot fill a court with three people.

Everyone plays at once only when your headcount is a multiple of four.

Minutes of padel each = booked minutes × 4 × courts ÷ players.

The last one is the honest one, and it is the number to quote in the group chat before anybody agrees to anything.

Two things fall out of that table, and both are worth knowing before you book anything.

A second court does nothing until you have eight players. Four bodies fill a court; five, six or seven people cannot fill two. That is why six or seven regulars is the most awkward number in padel — too many for one court, not enough for two — and why the fix is a headcount decision rather than a booking one.

Six people on one court for 90 minutes is one hour of padel each. Eight is forty-five minutes each: half a session, for a full share of the bill. Neither is wrong, but both should be a decision rather than a surprise, and the surprise is what makes the seventh player stop replying.

The sit-out schedules that make those numbers fair — everyone resting the same amount, in a stated order — are in padel with 5, 6 or 7 players, and the padel rotation planner will build them for four to ten players on one court with the rest and partner spread shown.

The cost result nobody expects

Ask a group why they invite two extra people and someone will say it makes the night cheaper. It does — but not in the way they think.

Say a court costs 30 for 90 minutes. Total player-minutes available is always 4 × 90 = 360, however many of you split it.

The last column does not move. Adding players does not make padel cheaper per hour played; it makes the evening cheaper and shorter. You are not buying a discount, you are buying a smaller portion.

That is worth knowing because it reframes the argument. If money is the constraint, more players genuinely helps — a fiver instead of a tenner is a real difference to a real person. If padel is the constraint, more players costs you playing time at exactly the same rate. Both are legitimate; they are just different purchases.

Three things do change the arithmetic for real:

• Balls. A tube shared four ways versus eight ways is the one genuine per-head saving in the whole calculation.
• No-shows. The court costs the same whether four or three arrive, and at three you cannot play 2v2 at all. A group of exactly four carries the whole cancellation risk on one absence, which is the strongest argument for a fifth name on the list.
• Guests and peak pricing. Both are policy rather than arithmetic. Settle them once — how to split padel court costs fairly has the rules that survive contact with friends, and the court cost splitter does the per-head sum including guest premiums and a no-show rule.

Courts by format

Different formats have different appetites for courts, and two of them deliberately want fewer.

Rotating-partner formats want players divisible by four, because that fills every court in every round. Padelution puts it plainly: "if you do not wish to have any breaks between matches, you should play with 4, 8, 12, 16, 20, etc. (divisible by 4) players" (Padel Americano). At 9, 10, 13 or 14 players somebody sits every round and the sit-outs have to be shared exactly evenly, or the final table is not comparable.

Fixed-pair events need the same court count but an even number of pairs, which is a different constraint: 7 pairs on 4 courts means one pair sits every round.

Winner-stays formats want the opposite — one court and a queue. That is their entire purpose: they absorb twelve people on a single court by making court time the prize. It is also why they are the most expensive format per minute played, and why nobody minds at a drop-in.

Box leagues are the most court-efficient structure in padel because they spread fixtures across weeks: one court, one fixture, arranged between the players themselves. If your problem is that your club has two courts and forty interested people, that is the shape to look at.

Booking strategy that survives real life

1. Book for confirmed players, not hoped-for players. Two courts booked for eight people who turn into five is an expensive lesson in optimism. Confirm first, book second.
2. Know your cancellation window. Most clubs release a court free up to a day or two ahead. That window, not your enthusiasm, decides whether "book two and cancel one" is a strategy or a donation.
3. Prefer two courts at the same time over one court twice as long. Same total padel, but everybody is in one place, the social half works, and nobody plays at 22:30.
4. Take the off-peak slot if your group can. The cheapest way to lower the per-head cost is not more players, it is a cheaper court — and off-peak often halves it.
5. Keep one reserve name per four players. A reserve list is cheaper than a cancellation and much cheaper than three people staring at an empty court.
6. For events, add a court before you add rounds. Halving your courts roughly doubles your duration; the full planning arithmetic for entries, rounds and durations is in how to organize a padel tournament.

The four-players-one-court sweet spot

Four on one court is the only configuration where the arithmetic has no waste in it, and it is worth stating why, because it is the shape most padel is actually played in.

Everyone plays every minute. No queue, no rota, no bench. You bought 360 player-minutes and you use 360.

The complete rotation fits. Four players make exactly three pairings, and playing all three means everyone has partnered everyone once and opposed everyone twice. Three matches, one court, 90 minutes — the night walked through in how to run a padel night for 4 friends.

The money is unambiguous. One court, four ways, no argument about who sat out and whether they should pay less.

The record is clean. Every result involves all four players, so the results compare directly, week after week. At six or eight players on one court, half your matches are missing half your group and any table you keep is patchier than it looks.

The cost of that tidiness is fragility: one absence cancels the night. The standard fix is a fifth or sixth name who rotates in, which trades some playing time for reliability — the trade-off in full is welcoming a fifth player without breaking a crew of four.

When to add the second court

The honest trigger is not headcount, it is playing time. If your group regularly puts six or seven people on one court, everybody is losing a third of their padel and paying for the privilege of watching. At that point you have three options, in order of how well they work:

Book two courts. Eight players, two courts, everyone plays everything. This is the answer if the eight are reliable.

Split into two nights. Four on Tuesday, four on Thursday, everyone plays a full session. Better padel, worse for the group's social gravity.

Cap the invite list. Unpopular, effective, and the most honest thing an organizer can do. Four confirmed players is a better night than seven maybes.

Where Rivals fits

Rivals is built around exactly the shape the arithmetic favours: one court, four players, a roster that rotates week to week. It keeps the fee ledger — who fronted the court, who owes, who has settled — so the money half of booking maths stops living in a chat thread, and it generates pairings from the crew's real ratings so the three pairings of a night are balanced rather than random.

What it does not do is book courts or run events for twenty entrants. Free is one crew of up to four players, with nothing inside it metered and no ads; a bigger roster is what Crew Pro lifts.

FAQ

How many courts do you need for 8 padel players?

Two, if you want everyone playing at the same time. Eight players on one court is 45 minutes of padel each in a 90-minute booking, with half the group resting every match. Two courts gives all eight a full session and is the standard club-social configuration for rotating-partner formats.

Can 6 people play padel on one court?

Yes, with a sit-out rota. Two players rest each match, so a 90-minute booking gives each person about an hour of padel. Keep the rest strictly equal and in a stated order, and keep matches short so the wait is never long. If it happens every week, a second court or a smaller list is the real fix.

How many players fit on one padel court?

Four for a normal match, and that number governs everything else: courts needed is players divided by four, rounded up. Some formats deliberately put more people around one court — winner-stays and king-of-the-court run a queue — but only four are ever playing at once.

Is padel cheaper with more players?

The evening is cheaper per person; the padel is not. A court has a fixed number of player-minutes, so the cost per hour of padel actually played stays the same however many of you split it — more players simply means each person buys a smaller portion. The genuine savings are shared balls and a cheaper off-peak slot.

How many courts do you need for 16 players?

Four courts for everyone to play at once, which is the standard for a 16-player event with rotating partners or eight fixed pairs. On two courts the same 16 players get about 45 minutes each in a 90-minute booking, so either book four courts or plan a format with an explicitly shared rota.
