Four in ten repeats on the MoonBoard 2016 are logged on a 6B+ (V4). On the Kilter Board Original 12×12 the busiest grade is 7A (V6), and the climbing is spread across the whole scale. The Tension Board 2 is spread wider still. Same angle, same sport, very different boards.
The short version
| Board (40°) | Problems listed | Busiest grade | Share of repeats at that grade | Share of problems at that grade |
|---|---|---|---|---|
| MoonBoard 2016 | 92,296 | 6B+ / V4 | 41% | 32% |
| MoonBoard Masters 2017 | 56,667 | 6A+ / V3 | 35% | 27% |
| MoonBoard Masters 2019 | 47,848 | 6A+ / V3 | 34% | 21% |
| MoonBoard 2024 | 34,161 | 6B+ / V4 | 39% | 23% |
| Mini MoonBoard 2020 | 7,904 | 6A+ / V3 | 45% | 27% |
| Kilter Board Original 12×12 | 106,034 | 7A / V6 | 14% | 15% |
| Tension Board 2 | 23,651 | 6B / V4 | 12% | 7% |
Three things jump out.
MoonBoards are warm-up machines. On every full-size MoonBoard the busiest grade takes a third or more of all repeats, and it is the easiest grade with a real population of problems: 6B+ on the 2016 and 2024 setups, 6A+ on the two Masters setups (which added a hold set of friendlier holds). The curve then falls off a cliff. On the 2016, 6B+ and 6C together take six repeats in ten.
Kilter spreads the load. The Original 12×12 has three separate humps, at 6A, 6B and 7A. Each is the first grade of a band where a climber settles for a while. The 7A peak is the one that surprises people: on a Kilter a 7A is where a strong gym climber lives, and there are nearly 16,000 of them to choose from.
Tension's climbers are the strongest, or the most honest. On the Tension Board 2 the mass sits at 6B, 6C, 7A and 7A+, with 7A and 7A+ together taking a fifth of all repeats. The TB2 also has by far the fewest listed problems of the three families, so its classics carry a bigger share each.
Board by board
MoonBoard 2016
| Grade | Problems listed | Share of problems | Share of repeats |
|---|---|---|---|
| 6B+ / V4 | 29,625 | 32% | 41% |
| 6C / V5 | 12,330 | 13% | 19% |
| 6C+ / V5 | 13,490 | 15% | 12% |
| 7A / V6 | 12,197 | 13% | 12% |
| 7A+ / V7 | 9,185 | 10% | 9% |
| 7B / V8 | 4,651 | 5% | 4% |
| 7B+ / V8 | 4,577 | 5% | 1% |
| 7C / V9 | 3,229 | 3% | 1% |
The 2016 is the board with the most history, and its 6B+ problems are where that history lives. An easy problem alone has more repeats than the 200 most-repeated 7B+ problems put together.
MoonBoard 2024
| Grade | Problems listed | Share of problems | Share of repeats |
|---|---|---|---|
| 6B+ / V4 | 7,932 | 23% | 39% |
| 6C / V5 | 5,403 | 16% | 23% |
| 6C+ / V5 | 4,462 | 13% | 11% |

| 7C / V9 | 1,766 | 5% | 1% |
| 7C+ / V10 | 1,100 | 3% | 1% |
Same shape as the 2016 eight years on. The new hold sets did not move the peak; 6B+ still takes 39% of repeats from 23% of problems.

| 7B+ / V8 | 1,698 | 4% | 1% |
| 7C / V9 | 1,292 | 3% | 1% |
The Masters setups are the only MoonBoards where 6A+ exists in volume, and climbers vote with their hands: a third of every repeat on each board is a 6A+.

Note the two columns. At 7A the share of repeats (14%) is about the same as the share of problems (15%). At 6A the repeats share is twice the problem share. Kilter's easy problems are few and very well used.

| 7C / V9 | 1,123 | 5% | 2% |
| 7C+ / V10 | 500 | 2% | 1% |
The flattest curve of the lot. No grade on the TB2 takes more than 13% of repeats.
How to use this
- If you set on a board, the busiest grade is where a new problem finds the most climbers. It is also where the catalogue is most crowded.
- If you climb on one, the grade just above your board's peak is where the catalogue thins out and quality problems get easier to find. On a 2016 that is 6C+ and 7A; on a Kilter it is 7A+.
- If you are switching boards, do not carry your grade across. The Kilter 7A climber and the MoonBoard 6B+ climber are very often the same person on a different day.
Method
Boardlordz lists every public problem on each board at 40°, with the repeat count climbers have logged through the board's own app. For each grade we summed the repeats on that grade's 200 most-repeated problems, which is the view a climber gets when they sort a grade by popularity. Because the long tail of rarely-climbed problems is cut at 200, the shares describe where the climbing happens rather than every ascent ever logged; on grades with fewer than 200 problems the sum is complete.
Grades are the setter's grade on the board's own scale, converted to the Font scale that Boardlordz uses everywhere, with the V-grade in brackets. Only 40° is counted. The Mini MoonBoard 2020 is in the summary table but has too few problems above 6C for a curve worth drawing.
