Bouldering grades
Climb Central grades with 'pies': a circle split into six slices pinned beside each climb, with more filled slices meaning harder. A photographed Climb Central 'Difficulty Chart' sign gives the V-grade band for each pie, from an empty pie (VB) to a full pie (harder than V8). The chart photo comes from a 2021 article; Coconuts describes the same pies at Climb Central's Bangkok gym, so we take them to apply at every Climb Central gym.
| Level | V-scale | ≈ Font |
|---|---|---|
| Empty pie (0 slices) | VB | 3 |
| 1 slice | V0–V1 | 4B–5B |
| 2 slices | V1–V2 | 5A–5C |
| 3 slices | V2–V4 | 5B–6B+ |
| 4 slices | V4–V6 | 6A+–7A |
| 5 slices | V6–V8 | 6C+–7B+ |
| 6 slices (full pie)Chart says '>V8' | ≥ V8 | ≥ 7B |
Rope climbing grades
Top-rope, auto-belay and lead routes use the same pie tags, and the same chart gives a French grade band for each pie. The chart writes the bands loosely (e.g. '6a/+'), so the table shows each band as the plain grade to the plus grade.
| Level | French | ≈ YDS |
|---|---|---|
| Empty pie (0 slices)Chart: '4' | 4a–4c | 5.6–5.7 |
| 1 sliceChart: '5/+' | 5a–5c | 5.8–5.10a |
| 2 slicesChart: '6a/+' | 6a–6a+ | 5.10a–5.10b |
| 3 slicesChart: '6b/+' | 6b–6b+ | 5.10c–5.11a |
| 4 slicesChart: '6c/+' | 6c–6c+ | 5.11a–c |
| 5 slicesChart: '7a/+' | 7a–7a+ | 5.11c–5.12a |
| 6 slices (full pie)Chart: '>7b' | ≥ 7b | ≥ 5.12b |
