How does the tennis ranking work in Belgium?

What are the rankings, in points and in letters?

For adults (from the under-15 category up), the scale starts at 3 points, moves to 5, then climbs in steps of 5 up to 110 points. The 115-point ranking is reserved for players with at least 10 ATP or WTA points.

Each value also has a letter name. Tennis Vlaanderen shows the points, Tennis Wallonie-Bruxelles still shows the letters, and the 2026 regulations use both. A C15 and a 60-point player therefore hold the same ranking. The full list:

• C30.6 = 3 points, C30.5 = 5, C30.4 = 10, C30.3 = 15, C30.2 = 20, C30.1 = 25, C30 = 30
• C15.5 = 35, C15.4 = 40, C15.3 = 45, C15.2 = 50, C15.1 = 55, C15 = 60
• B+4/6 = 65, B+2/6 = 70, B0 = 75, B-2/6 = 80, B-4/6 = 85, B-15 = 90, B-15.1 = 95, B-15.2 = 100, B-15.4 = 105
• A National = 110, A International = 115

From 95 points (B-15.1), an order number is added to the ranking. It sets tournament seeds and the order of players in interclub.

How many points does a tournament give?

Each tournament draw you play gives you the sum of three amounts:

• Round reached: points for the round where you stop, from the category's points table. If you lose your first match, you get none.
• Win bonus: for each match won, the points value of your opponent's ranking. Beating a C15 gives 60 points, beating a C30.4 gives 10.
• Participation bonus: 2 points per match played, unless you lose the first one.

Round-reached points grow with the level of the category. For men, winning the draw is worth 63 points in M6 (rankings from 3 to 10 points), 270 in M4 (35 to 50) and 1,160 in M2 (75 to 90). For women, it is worth 63 points in D5 (3 to 10) and 560 in D2 (65 to 85).

Those round-reached points then depend on the number of players in the draw: 60% with 2 or 3 players, 85% with 4 to 7, 90% with 8 to 11, 95% with 12 to 15, 100% with 16 to 23, 105% with 24 to 31 and 110% from 32. The two bonuses do not change. The Masters (final stage of the regional criteriums) and the Belgian Circuit finals give their points at 100% from the first match, whatever the number of entries.

How does interclub count?

Your interclub matches count as a single competition within your best 6. Only wins give points, from a separate interclub table based on your opponent's ranking. For men, a win against a 15-point player is worth 105 points, against a 30-point player 205, and against a 60-point player 555.

Your 3 best wins count. With 3 wins, their total is taken at 100% and divided by 3; with 2, at 80% and divided by 2; with one, at 60%. Without a win, your interclub gives nothing, but the matches played still count towards the minimum of 2 official matches.

Interclub is always played with the ranking calculated in October, even after the May ranking is published.

How do your results become a ranking?

At calculation time, your 6 best results from the last 12 months are taken, tournaments and interclub together, and their sum is divided by 6. You need at least 2 official singles matches over the period to be calculated.

If you scored points in fewer than 6 competitions, the total is reduced before the division: 80% for one competition, 84% for two, 88% for three, 92% for four and 96% for five. A tournament where you scored no points does not count.

That score does not give you a ranking directly. It places you in a pyramid where each value gets a fixed share of the calculated players. Among adult men, 23.4% are at 3 points, 18.6% at 5 points, 13.6% at 10 points and 0.1% at 110 points. Among women, 25% are at 3 points, 19% at 5 points and 0.1% at 110 points.

After each calculation, the federation publishes the "cuts": the minimum and maximum score for each value. At the October 2026 calculation, men needed between 105.600 and 128.184 points for 30 points (C30), between 331.564 and 394.700 for 60 points (C15), and between 1,184.433 and 1,478.767 for 90 points (B-15). For women, 30 points ran from 113.931 to 136.533 and 60 points from 270.522 to 309.058.

These thresholds move with every calculation, because the percentages are fixed while everyone's scores change. Tennis Wallonie-Bruxelles states that the next cuts cannot be predicted. A score worked out in advance is an estimate, not a guarantee.

A full worked example

Take a player ranked C30.2 (20 points) who played three tournaments and interclub over the last 12 months.

First tournament: an M5 draw (rankings from 15 to 30 points) with 16 entries, so round-reached points at 100%. He beats a C30.3 (15 points), then loses in the quarter-final. He gets 75 points for the quarter-final, a 15-point win bonus and 4 participation points for his 2 matches: 94 points.

Second tournament: 70 points. Third tournament: a first-round loss, so 0 points, and that tournament does not count.

In interclub, he wins 3 matches against players at 15, 20 and 25 points. The men's table gives 105, 135 and 168 points: (105 + 135 + 168) ÷ 3 = 136 points.

He scored points in 3 competitions, for a total of 94 + 70 + 136 = 300 points. With 3 competitions, you take 88% of the total and divide by 3: 300 × 88% ÷ 3 = 88 points.

With the October 2026 cuts, 88 points fell within the men's 25-point range (86.988 to 105.600). He would move from C30.2 to C30.1. With at least 4 wins over the period, the promotion rule allows two rankings, so this step is not held back.

How many rankings can you move up or down?

Moving up depends on the number of matches won during the period. No win, no promotion; 1 or 2 wins, one ranking at most; 3 or 4 wins, two rankings. From 5 wins, promotion is unlimited if you played at least 2 competitions, and capped at two rankings if you played only one. Walkover (WO) wins do not count for these thresholds.

Relegation is limited to one ranking per calculation, and a calculated player cannot lose a ranking in two calculations in a row. Between 14 and 34, successive drops are capped at 4; from 35, they are not. Once you reach C30.5 (5 points), you never drop back to C30.6.

If you go 18 months without playing enough to be calculated (0 or 1 match), you automatically drop one ranking.

When does the new ranking apply?

In 2026, the first calculation took place in the week of 11 May (results from 12 May 2025 to 10 May 2026) and the second in the week of 28 September (results from 20 October 2025 to 27 September 2026). New rankings are published no later than 10 days after the calculation.

Tournaments held during the calculation period are still played with the old ranking. In May 2026, entries made until Tuesday 26 May for tournaments ending on Sunday 7 June used the October 2025 rankings; from Wednesday 27 May, tournaments ending on 14 June and later used the May 2026 rankings. For the October calculation, entries for tournaments starting from Thursday 15 October 2026 opened on Monday 5 October.

What about juniors?

Players under 9, 11 and 13 have their own pyramids, with rankings from .8 (beginner) to .1. A player who joins without a ranking receives .8 or C30.6, depending on age.

At each calculation, the top 0.5% of under-13 players by points move permanently into the adult pyramid, with at least 30 points (C30).

Where can you follow your ranking?

On GameSetMatch, every competitive player from both federations has a profile with their current ranking and its date, their matches and their ranking history. You can follow your own progress and look up any other player.
