Card betting: booking points, yellow cards only and card points
A card bet settles on one of several counts, and the name of the market does not always tell you which. The usual measure at UK bookmakers is booking points: 10 for a yellow card and 25 for a red, with a player capped at 35, so a player sent off for two yellows counts 35. Other bookmakers count yellow cards only, or card points, in which a yellow counts 1, a red 2 and a sending-off after two yellows 3. The same line is therefore a different bet under each count: in 14,277 matches from 34 leagues, over 4.5 yellow cards landed in 36.2% of matches and over 4.5 card points in 41.9%. We explain what each count includes, what the three recreational bookmakers we track count, how much the referee matters and where it is easiest to go wrong.
Key takeaways
- 1
Booking points, the usual card market in the UK, give 10 for a yellow and 25 for a red, capped at 35 a player, and over 45.5 landed in 41.8% of 14,277 matches.
- 2
A yellow-cards-only bet ignores red cards, and a player sent off for two yellows counts as one yellow there, 3 in card points and 35 in booking points.
- 3
Cards for the manager and the bench, after the final whistle and in extra time count at none of the three bookmakers we track.
- 4
The league changes a lot: over 4.5 yellow cards landed in 11.8% of J1 League matches, 34.2% of Premier League matches and 54.0% of Liga Portugal matches.
- 5
A referee 0.8 cards stricter than the league average showed only about 0.2 cards more than average in his following matches.
Four ways to count cards
Cards are the only popular market where bookmakers do not even agree on what to count. You will come across four definitions. The "Where" column shows which of the three recreational bookmakers we track (A, B and C, whose rules we read on 4 October 2026) uses each one:
| Definition | Where | Yellow | Straight red | Two yellows (sending-off) | Average per match | Over 4.5 |
|---|---|---|---|---|---|---|
| Booking points | Bookmaker C, Bookmaker A's bet builder | 10 | 25 | 35 | 43.9 | over 45.5: 41.8% |
| Yellow cards only | Bookmakers A and B | 1 | 0 | 1 | 3.92 | 36.2% |
| Card points | Bookmaker C ("Number of cards"), Bookmaker A | 1 | 2 | 3 | 4.29 | 41.9% |
| Every card as one | none of the three | 1 | 1 | 2 | 4.11 | 39.5% |
The averages and frequencies come from 14,277 matches in 34 leagues (January 2025 to September 2026), counted the way bookmakers count them: cards in 90 minutes plus stoppage time, without extra time.
The last row is how match stats usually count cards: every card shown is one. None of the three bookmakers we track offers a bet on that count, so the number of cards in the match stats does not tell you directly how your bet will settle.
An example: one match, three different results
In one match the referee shows these cards:
| Event | Booking points | Yellow cards only | Card points |
|---|---|---|---|
| 20': yellow for player 1 | 10 | 1 | 1 |
| 35': yellow for player 2 | 10 | 1 | 1 |
| 60': yellow for player 3 | 10 | 1 | 1 |
| 75': second yellow and a red for player 1 | 25 (player 1: 35 in total) | 0 | 2 (player 1: 3 in total) |
| 88': straight red for player 4 | 25 | 0 | 2 |
| 90+2': yellow for the manager | 0 | 0 | 0 |
| Total | 80 | 3 | 7 |
| Line 4.5 (booking points: 45.5) | over | under | over |
The referee showed six cards, but a yellow-cards-only bet settles on three of them and a card-points bet on seven. Over 4.5 yellow cards at Bookmaker B lost, while over 4.5 on Bookmaker C's "Number of cards" won, and so did over 45.5 booking points. The red cards make the difference: a yellow-cards-only count does not see them, and player 1's second yellow does not count there at all.
In our sample this kind of split on the 4.5 line (yellow cards under, card points over) happened in 5.6% of matches, roughly one in eighteen.
Who counts what: three bookmakers' rules
We read the terms, market rules and notices of the three recreational bookmakers we track on 4 October 2026:
| Bookmaker A | Bookmaker B | Bookmaker C | |
|---|---|---|---|
| Card markets | yellow cards only (match) and card points (match and teams) | yellow cards only (match), red cards separately | "Number of cards" = card points (match and teams), red cards separately |
| Second yellow | yellow cards only: counts as one yellow (not two); card points: 3 for the player in total | the second yellow does not count | a sending-off for two yellows counts as 3 |
| Bench, manager, staff | do not count | do not count | do not count |
| Card after the final whistle | does not count | does not count | does not count |
| Card at half-time | counts for the match, not for either half | no rule | counts for the second half if the player plays on |
| Period | 90 minutes plus stoppage time | regulation time | 90 minutes plus stoppage time |
| Whole line (4.0 or 5.0) | push when the count equals the line | no rule, x.5 lines on offer | no rule, x.5 lines on offer |
| Result source | "official sources" | yellow cards per Opta data | "official sources" |
| Booking points 10/25 | in its bet builder, at most 35 a player | none | in its football notice, at most 35 a player |
The main traps:
- The market name is not the definition. At Bookmaker C a market called "Number of cards" is card points: two yellows for one player make 3, not 2. Before you bet, open the market description or the rules.
- Yellow cards only do not see red cards. A match with four yellows and two straight reds is under 4.5 yellow cards, but over 4.5 card points (4 + 2 + 2 = 8) and over 45.5 booking points (40 + 25 + 25 = 90).
- The second yellow. In a yellow-cards-only market a player sent off for two yellows counts as one yellow. In card points he counts 3, in booking points 35.
- The bench and the manager. A card for the manager, a substitute or a team official is in the match report and often in the stats, but counts towards none of these bets.
- Extra time. Cards in extra time do not count towards the bet. In a cup match the full-match stats can therefore show more cards than the settlement.
The general rules (a postponed match, the official result, complaints) are covered in our article on bet settlement rules.
How many cards: 14,000 matches in numbers
The same sample as above: 14,277 matches, cards in 90 minutes plus stoppage time.
| Line | Yellow cards only: over | Card points: over | Fair odds on over: yellows / card points |
|---|---|---|---|
| 2.5 | 73.9% | 76.5% | 1.35 / 1.31 |
| 3.5 | 55.0% | 59.2% | 1.82 / 1.69 |
| 4.5 | 36.2% | 41.9% | 2.76 / 2.39 |
| 5.5 | 21.0% | 27.4% | 4.76 / 3.65 |
| 6.5 | 11.1% | 16.8% | 9.01 / 5.95 |
Fair odds are 1 divided by the frequency, without margin. On the 4.5 line the gap between the two definitions is almost 6 percentage points, and in fair odds 2.76 against 2.39. If you judged the chance of over 4.5 from yellow cards only and then bet on card points (or the other way round), you would be wrong by roughly as much as the bookmaker's entire margin on such a market.
A few numbers worth knowing:
- A red card comes up in 16.5% of matches: a straight red in 10.4%, a sending-off for two yellows in 7.1%. Fair odds on "red card in the match: yes" are therefore about 6.0.
- Two-thirds of cards come after the break. The first half has only 33.7% of cards.
- Away sides get more yellows: 2.10 a match on average against 1.82 for home sides.
- Team card points. The home side went over 1.5 card points in 57.6% of matches, the away side in 65.5%. Over 2.5: 31.3% and 39.8%.
- Booking points are in practice card points multiplied by ten, except that a straight red gives 25 rather than 20 and a sending-off for two yellows 35 rather than 30. The 45.5 booking-points line therefore lands almost exactly as often as 4.5 card points (41.8% against 41.9%), and a match averages 43.9 booking points.
- A match without a single yellow card is rare: 3% of matches.
Cards by league
| League | Matches | Yellows per match | Over 4.5 yellows | Matches with a red card |
|---|---|---|---|---|
| Premier League | 562 | 3.77 | 34.2% | 11.2% |
| Championship | 820 | 3.70 | 31.7% | 10.2% |
| League One | 635 | 3.71 | 31.8% | 9.8% |
| LaLiga | 598 | 4.28 | 42.8% | 22.2% |
| Bundesliga | 457 | 3.60 | 30.9% | 15.3% |
| Serie A | 562 | 3.64 | 29.2% | 14.1% |
| Ligue 1 | 470 | 3.61 | 29.6% | 20.6% |
| Eredivisie | 507 | 3.01 | 19.9% | 13.8% |
| Liga Portugal | 474 | 4.85 | 54.0% | 21.3% |
| Champions League | 276 | 3.73 | 36.6% | 19.2% |
| Liga Profesional (Argentina) | 404 | 4.80 | 53.2% | 20.0% |
| J1 League (Japan) | 280 | 2.55 | 11.8% | 13.2% |
The calmest league in the sample, Japan's J1 League, averages 2.55 yellow cards a match, and the harshest, Portugal's second division, 5.50. The 4.5 line lands in about one match in eight in Japan and in almost two in three in Portugal's second division. The Premier League sits in between: 3.77 yellows a match and over 4.5 in 34.2% of matches. English football has the fewest red cards in the table: there was one in 11.2% of Premier League matches, 10.2% of Championship matches and 9.8% of League One matches.
The referee: important, but less than the averages suggest
The spread between referees is wide. In the Premier League, referees who have taken charge of at least 20 matches since January 2025 averaged from 2.80 to 4.96 yellow cards a match, in LaLiga from 2.95 to 5.25, and in the Championship from 2.71 to 4.85, against an average of 3.75 in its matches with a known referee.
An average over a dozen or a few dozen matches is, however, largely chance. We checked it fairly, only on matches played later:
| Referee in previous matches (at least 10) | Matches | Yellows in the next match | League average | Over 4.5 |
|---|---|---|---|---|
| strict: at least 0.8 yellows above the league average | 655 | 4.22 | 4.03 | 42.3% |
| average | 4,144 | 3.84 | 3.92 | 34.5% |
| lenient: at least 0.8 yellows below the average | 801 | 3.58 | 4.11 | 29.5% |
A referee who had shown 0.8 cards more than the average went on to show only about 0.2 more in his following matches. The difference persists, but it shrinks. It is the same regression to the mean that we describe in the late goals myth. That is why in our model the referee carries more weight the more matches he has refereed, and never decides a tip on his own.
The favourite, fouls and close games
- Close matches have more cards. With the favourite's chance below 40% there are 4.14 yellow cards a match on average, at 70% or more only 3.27. The weaker side then gets 1.94 yellows and the favourite 1.33.
- More fouls mean more cards. There are 5.7 fouls per yellow card on average. Matches with at least 30 fouls averaged 5.1 yellows, matches with 17 fouls or fewer 3.0. More on this in our article on fouls betting.
Cards on SharkBetz
- On our football tips, the cards forecast shows the expected number of yellow cards in the match, the league average and the chance of going over the league's line, and the referee's figures show how many yellow cards the referee shows compared with the league average. The details are in how to read football tips.
- We give card tips in the bookmakers' own definitions, on yellow cards only or on card points, and only when the bookmakers we track offer that market.
- When the referee is not known by the time the tips come out, a card tip may follow once he is appointed. We explain this in how we publish tips.
Corners are simpler to settle: there the three bookmakers count the same thing.

What to watch out for
- Read the market description, not just its name. "Cards" can mean booking points, yellow cards only or card points.
- Do not compare odds across definitions. Over 4.5 yellow cards at Bookmaker B and over 4.5 in Bookmaker C's "Number of cards" are different bets, so the "better odds" at one of them need not be better. This matters most when you look for surebets: a difference in definition can turn a sure profit into two losing bets.
- Opta and other sources. Bookmaker B settles yellow cards on Opta data, the other two on "official sources". When the sources differ over a single card (whether it went to a player on the pitch or on the bench, for example) and the result sits on the edge of the line, the bookmaker's data supplier decides.
- Older descriptions. Bookmaker B's help pages from 2024 say cards are counted from the match report, after the final whistle too, while the newer market name excludes those. Its terms say the rules given in the offer apply, so the market description decides.
- Bet responsibly. A single red card can decide a bet in the last minute. Card bets are volatile, and a run of misses comes easily.
FAQ
Booking points count cards as points: 10 for a yellow card and 25 for a red, with a maximum of 35 per player. They are the usual card market in the UK. Of the three bookmakers we track, one describes booking points in its football rules and another uses them in its bet builder. Over 45.5 booking points landed in 41.8% of 14,277 matches, about as often as over 4.5 card points.
No. In a yellow-cards-only market a straight red card does not count, and a player sent off for two yellows counts as one yellow. Red cards are bet on in separate markets.
In card points, a player sent off for two yellows counts 3 in total: 1 for the first yellow and 2 for the sending-off. In booking points it is 35 (10 + 25).
Not always cards. At one of the three bookmakers we track, a market called "Number of cards" is card points, not a count of cards: a yellow 1, a red 2, a sending-off for two yellows 3. Cards for the bench and staff and after the final whistle do not count, and the settlement covers 90 minutes plus stoppage time. Always open the market description.
No. The three bookmakers we track count only cards for players on the pitch. Cards for the manager, the staff and substitutes on the bench do not count towards the bet, and neither do cards after the final whistle.
No. All three bookmakers we track settle cards on 90 minutes plus stoppage time. Extra time and penalties have no effect on the bet.
In 14,277 matches from 34 leagues there were 3.92 yellow cards and 4.29 card points a match on average. By league, from 2.55 yellow cards in Japan to 4.85 in Portugal and 5.50 in Portugal's second division, with the Premier League at 3.77.
