In matchpoint scoring each contestant is awarded, for scores made by different contestants who have played the same board and whose scores are compared with his, two scoring units (matchpoints or half matchpoints) for each score inferior to his, one scoring unit for each score equal to his, and zero scoring units for each score superior to his.
In international matchpoint scoring, on each board the total point difference between the two scores compared is converted into IMPs according to the following scale.
| Difference in points | IMPs | Difference in points | IMPs | Difference in points | IMPs |
|---|---|---|---|---|---|
| 0-10 | 0 | 370-420 | 9 | 1500-1740 | 17 |
| 20-40 | 1 | 430-490 | 10 | 1750-1990 | 18 |
| 50-80 | 2 | 500-590 | 11 | 2000-2240 | 19 |
| 90-120 | 3 | 600-740 | 12 | 2250-2490 | 20 |
| 130-160 | 4 | 750-890 | 13 | 2500-2990 | 21 |
| 170-210 | 5 | 900-1090 | 14 | 3000-3490 | 22 |
| 220-260 | 6 | 1100-1290 | 15 | 3500-3990 | 23 |
| 270-310 | 7 | 1300-1490 | 16 | 4000+ | 24 |
| 320-360 | 8 |
In total point scoring, the net total point score of all boards played is the score for each contestant.
If approved by the Regulating Authority other scoring methods (for example conversions to Victory Points) may be adopted. The Tournament Organizer should publish Conditions of Contest in advance of a tournament or contest. These should detail conditions of entry, methods of scoring, determination of winners, breaking of ties, and the like. The Conditions must not conflict with law or regulation and shall incorporate any information specified by the Regulating Authority. They should be available to contestants.
